    Bismuth and Silver in Cosmetic Products: A Source of Environmental and Resource Concern?2016Ingår i: Journal of Industrial Ecology, ISSN 1088-1980, E-ISSN 1530-9290, Vol. 20, nr 1, s. 99-106Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Bismuth (Bi) and silver (Ag) are used in increasing amounts and are consequently being emitted from various sources and showing high accumulation rates in soils when sewage sludge is applied on arable land. This study aimed to analyze the amounts of Bi and Ag in three cosmetic products (foundation, powder, and eye shadow) in order to study the flows in urban wastewater in Stockholm, Sweden. Analyses showed that Bi was present in very high concentrations (7,000 to 360,000 milligrams per kilogram) in one third of the analyzed foundation and powder samples, whereas Ag concentrations all were below the detection limit. These cosmetic products explained approximately 24% of the measured total Bi amounts per year reaching the WWTP (wastewater treatment plant), making cosmetics a major Bi source, whereas for Ag the corresponding contribution was <0.1% of the measured annual Ag amounts. The results were roughly adapted for Europe and the United States, estimating the Bi flows from cosmetics to WWTPs. On a global scale, these flows correspond to a non-negligible part of the world Bi production that, every year, ends up in sewage sludge, limiting the reuse of a valuable metal resource. From an environmental and resource perspective, foundations and powder products should be considered as significant sources of measured Bi amounts in sludge. This large Bi flow must be considered as unsustainable. For Ag, however, the three analyzed cosmetic products are not a significant source of the total Ag load to WWTPs.

    Monitoring urban copper flows in Stockholm, Sweden: implications of changes over time2017Ingår i: Journal of Industrial Ecology, ISSN 1088-1980, E-ISSN 1530-9290, Vol. 21, nr 4, s. 903-912Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study, a substance flow analysis (SFA) for copper (Cu) was conducted, in which theinflow, stock, and outflow (in the form of diffuse emissions to soil and water) for Stockholmwere estimated for 2013 and compared with a previous study from 1995, hence allowing adiscussion on changes over time. A large number of applications containing Cu were analyzed(including power cables, copper alloys, heavy electrical equipment, tap water systems, roofs,cars, various consumer electronics, wood preservatives, and contact cables for the railroad).The results show that the inflow of Cu to Stockholm has increased between 1995 and 2013,both in total and per person, mainly as the result of an increase in heavy electrical equipment,power cables, and cars. The stock remains relatively unchanged, whereas the outflow hasincreased. For the outflow, the emission increase from brake linings is of greatest quantitativeimportance, with an estimated 5.8 tonnes annual emission of Cu to the environment ofStockholm in 2013 compared to 3.9 tonnes in 1995. Given that increasing inflows of limitedresources drive the global demand, continuous monitoring of flows through society andmanagement of outflow routes are crucial, including improvement of national legislationand regional environmental plans as well as efforts to increase resource-use efficiency andrecycling

    Strategier att reducera silver och vismut i urbant avloppsvatten2014Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Silver och vismut är två metaller som på sikt kan anrikas i mark i samband med slamspridning och som därför är prioriterade enligt REVAQ, ett certifieringssystem för svenska reningsverk.

    I Naturvårdsverkets förslag till ny författning (slamförordning) föreslås gränsvärden för bland annat silver. Silver är en toxisk tungmetall med antibakteriella egenskaper som ger skadliga effekter på båda människors hälsa och miljö redan vid låga koncentrationer. Vismut är en tungmetall som anses vara ”ogiftig” men som också kan ge skadliga effekter vid högre koncentrationer.

     

    En substansflödesanalys utfördes för båda metallerna för att kartlägga inflödet till, stocken (upplagrad mängd i teknosfären) och utflödet från Stockholm under 2012. Avgränsning har gjorts till utflöden som hamnar i avloppsvattnet och på det sättet påverkar Henriksdals reningsverk. Utflödet i substansflödesanalysen blir därmed lika med ett inflöde till reningsverket. Fokus ligger på diffusa utsläpp av silver och vismut, men identifierade punktkällor räknas in i det slutliga resultatet med målet att förklara så mycket som möjligt av de uppmätta halterna av silver och vismut i Henriksdals reningsverk. Källor som har ett utflöde till avfall eller återvinning har inte inkluderats i denna rapport.

     

    För år 2102 uppmättes en tillförsel av 61 kg silver och 116 kg vismut för Henriksdals reningsverk i Stockholm. Källor har identifierats för ca 56 % av uppmätt silver och 49 % av uppmätt vismut i denna studie. De källor med störst bidrag silver bedöms vara textilier (19 %), urin och fekalier (från bland annat amalgamfyllningar och föda) (15 %) samt städprodukter (7 %). För vismut är det kosmetika (23 %), plast (13 %) samt fordonstvättar (9 %) som bedöms vara källor med störst bidrag.

     

    Utifrån erhållna resultat föreslår vi några åtgärder/strategier för reduktion av silver respektive vismut i urbant avloppsvatten. Vi diskuterar även aktörer som har möjlighet/rådighet att genomföra åtgärderna (Svenskt Vatten, avloppsreningsverk, myndigheter, producenter, verksamhetsutövare samt individer/konsumenter). En strategi som föreslås är att myndigheter ska informera och påverka producenter och verksamhetsutövare när det gäller silver och vismut i olika produkter samt verka för ändrad lagstiftning. Producenter kan ta ett eget ansvar att minska silver- och vismutinnehåll i produkter. Två identifierade kunskapsluckor och potentiella källor är silver i städprodukter samt vismut i plast.

    Bismuth in cosmetic products and its implications for sewage sludge management2015Ingår i: SETAC Europe 25th Annual Meeting, Barcelona, 3-7 May, 2015, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Bismuth (Bi) is a heavy metal that over recent years has shown increasing concentrations in sewage sludge in Swedish wastewater treatment plants (WWTPs), indicating an increasing Bi use in the society. The high accumulation rate of Bi in soil when sewage sludge is used as fertilizer on arable land is of environmental concern. Bismuth is used in various consumer products to replace lead, but which sources in the society that explain the increasing amount of Bi in sewage sludge in the municipal WWTPs is however unknown. This study aimed to analyze one product group suspected to contain Bi, cosmetics, and three different products were chosen (foundation, powder and eye shadow) in order to study the flows in urban wastewater in Stockholm, Sweden. The chemical analyses showed that Bi was present in very high concentrations (>100 000 mg/kg) in one third of the analyzed foundation and powder samples, while mainly low concentrations were found in eye shadow. These cosmetic products explained approximately 24 % of the measured total Bi amounts reaching the WWTP in 2012, making cosmetics a major Bi source. It is therefore recommended to monitor the Bi concentrations in sewage sludge regularly. Efforts should be made to further examine the sources of Bi to WWTPs and to decrease the emission from Bi in cosmetics to the WWTPs.

    The Increase in Bismuth Consumption as Reflected in Sewage Sludge2015Ingår i: Water, Air and Soil Pollution, ISSN 0049-6979, E-ISSN 1573-2932, Vol. 226, nr 4, s. 1-11, artikel-id 92Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    As the use of dangerous substances in consumer products increases, these substances may also be found in society’s end products, among them sewage sludge. Measuring concentrations in sewage sludge can be a way to reflect the consumption of a substance. By using substance flow analysis, the inflow, stock and outflow of the specific substance to, e.g. a city region, may be analysed. Bismuth is a heavy metal that is found in increasing levels in sewage sludge in Swedish wastewater treatment plants (WWTPs) and a similar increase cannot be excluded for WWTPs around the world. This study aims to examine possible sources that could explain the amounts measured in one Swedish WWTP. Household products such as cosmetics (24 %) and plastics (14 %) are found to be major sources of Bi measured in sewage sludge. The remaining unidentified amounts in this study (approximately 50 %) are most likely found in effluent waters from industries or sources outside the household. There is, however, no information on measurements of Bi released by industry available and there is no legislation in place that may encourage industry to conduct such measurements.

    Trace metals in recharge and discharge ground waters at two sites at the Baltic coast of Sweden2009Ingår i: Applied Geochemistry, ISSN 0883-2927, E-ISSN 1872-9134, Vol. 24, nr 9, s. 1640-1652Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The distribution and controls of trace elements (Cd, Cr, Cu, Ni, Pb, Zn and U) in shallow groundwater in discharge and recharge zones were analysed at two sites on the Baltic coast of Sweden; one granite-dominated and one with a significant addition of calcite. Although the study sites differ in overburden geochemistry and groundwater trace metal concentrations, which were well reflected in the general groundwater composition, the relative hydrochemical differences between recharge and discharge ground waters were similar at both sites, and temporally stable. The concentrations of Cd, Cu, Ni and U were higher in soil tubes in recharge areas, but Cr was higher in discharge zones. Also concentrations of HS, Fe, Mn and NH4 were higher in discharge samples, which in combination with increased 34S values provide strong evidence of a transition from oxidizing to more reducing conditions along the groundwater flow gradient. In terms of trace metals, this might mean either mobilisation due to dissolution of trace-metal carrying Fe(III) and Mn(IV) phases, or immobilisation caused by precipitation of discrete trace-metal sulfides or co-precipitation with Fe sulfides. The results from this study show that the latter is dominant in both the carbonate and granite environments for the metals Cd, Cu and Ni. Chromium concentrations were likely coupled to organic complexation and were higher in discharge groundwater, where DOC was also more abundant. As the concentration of several potentially toxic trace metals were found to differ between recharge and discharge areas, a climate driven change in hydrology might have a substantial impact on the distribution of these metals.

    Assessing the risk of an excess fluoride intake among Swedish children in households with private wells: Expanding static single-source methods to a probabilistic multi-exposure-pathway approach2014Ingår i: Environment International, ISSN 0160-4120, E-ISSN 1873-6750, Vol. 68, s. 192-199Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It is often assumed that water consumption is the major route of exposure for fluoride and analysis of water fluoride content is the most common approach for ensuring that the daily intake is not too high. In the present study, the risk of excess intake was characterized for children in households with private wells in Kalmar County, Sweden, where the natural geology shows local enrichments in fluorine. By comparing water concentrations with the WHO drinking water guideline (1.5 mg/L), it was found that 24% of the ca. 4800 sampled wells had a concentration above this limit, hence providing a figure for the number of children in the households concerned assessed to be at risk using this straightforward approach. The risk of an excess intake could, alternatively, also be characterized based on a tolerable daily intake (in this case the US EPA RfD of 0.06 mg/kg-day). The exposure to be evaluated was calculated using a probabilistic approach, where the variability in all exposure factors was considered, again for the same study population. The proportion of children assessed to be at risk after exposure from drinking water now increased to 48%, and when the probabilistic model was adjusted to also include other possible exposure pathways; beverages and food, ingestion of toothpaste, oral soil intake and dust inhalation, the number increased to 77%. Firstly, these results show how the risk characterization is affected by the basis of comparison. In this example, both of the reference values used are widely acknowledged. Secondly, it illustrates how much of the total exposure may be overlooked when only focusing on one exposure pathway, and thirdly, it shows the importance of considering the variability in all relevant pathways.

    Climate change - an uncertainty factor in risk analysis of contaminated land2011Ingår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 409, nr 22, s. 4693-4700Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Metals frequently occur at contaminated sites, where their potential toxicity and persistence require risk assessments that consider possible long-term changes. Changes in climate are likely to affect the speciation, mobility, and risks associated with metals. This paper provides an example of how the climate effect can be inserted in a commonly used exposure model, and how the exposure then changes compared to present conditions. The comparison was made for cadmium (Cd) exposure to 4-year-old children at a highly contaminated iron and steel works site in southeastern Sweden. Both deterministic and probabilistic approaches (through probability bounds analysis, PBA) were used in the exposure assessment. Potential climate-sensitive variables were determined by a literature review. Although only six of the total 39 model variables were assumed to be sensitive to a change in climate (groundwater infiltration, hydraulic conductivity, soil moisture, soil:water distribution, and two bioconcentration factors), the total exposure was clearly affected. For example, by altering the climate-sensitive variables in the order of 15% to 20%, the deterministic estimate of exposure increased by 27%. Similarly, the PBA estimate of the reasonable maximum exposure (RME, defined as the upper bound of the 95th percentile) increased by almost 20%. This means that sites where the exposure in present conditions is determined to be slightly below guideline values may in the future exceed these guidelines, and risk management decisions could thus be affected. The PBA, however, showed that there is also a possibility of lower exposure levels, which means that the changes assumed for the climate-sensitive variables increase the total uncertainty in the probabilistic calculations. This highlights the importance of considering climate as a factor in the characterization of input data to exposure assessments at contaminated sites. The variable with the strongest influence on the result was the soil:water distribution coefficient (Kd).

    Effects of land use and climate change on erosion intensity and sediment geochemistry at Lake Lehmilampi, Finland2013Ingår i: The Holocene, ISSN 0959-6836, E-ISSN 1477-0911, Vol. 23, nr 9, s. 1247-1259Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper aims to evaluate the possible relationships between erosion intensity and changes in climate and land use during the past 5.5 cal. k years at Lake Lehmilampi, eastern Finland. In this study we compare a detailed geochemical sediment record with (1) forest and land use history inferred from the first pollen and charcoal records from Lake Lehmilampi, and (2) existing archaeological surveys and independent proxy-records of climate change in the study region. The physical and geochemical sediment parameters examined include grain size analysis data and 23 chemical elements, determined with four selective extractions and ICP-MS. There are indications of possible human impact in the lake catchment as early as the Neolithic period, c. 3000-2550 bc, but the first undisputable signs are dated to 1800-100 bc. Cereal pollen reappears at c. ad 1700 and increases rapidly until c. ad 1950. The Holocene Thermal Maximum, its end c. 2000 bc, and the Medieval Climate Anomaly' were major climate events that had a prominent effect on erosion intensity, while human impact was a more significant factor during the period 3000 bc-ad 800 and from ad 1500 onwards. Although signs of changes in erosion intensity found in the sediment were small in this small catchment, they were significant enough to have a clear impact on the fraction of potentially mobile element species. This fraction increases with decreasing erosion intensity, which is probably related to a higher degree of chemical weathering and leaching during periods of decreased erosion.

    Trace metal and geochemical variability during 5,500 years in the sediment of Lake Lehmilampi, Finland2010Ingår i: Journal of Paleolimnology, ISSN 0921-2728, E-ISSN 1573-0417, Vol. 44, nr 4, s. 1025-1038Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A high-resolution geochemical profilefrom a 5,500-year-old sediment core of Lake Lehmilampiin eastern Finland was analyzed to study longtermtrends and variability in element concentrationsand accumulation rates. The accumulation rates of allstudied elements followed the same trend, respondingto changes in the total sedimentation rate. Concentrationprofiles differed among elements and showedconsiderable variation over time. Principal componentsanalysis (PCA) was used on the concentrationdata to identify groups of elements that have similargeochemical controls. The first principal componentwas influenced by changes in mineral matter accumulation,and it incorporated elements that areassociated with stable allochthonous minerals (suchas Mg, K, Cs, Rb, Li, Ti and Ga), as well as elementsin forms that become diluted when mineral matterincreases (e.g., S, Fe and Mn). The second and thirdprincipal components showed that a large proportionof the variance was accounted for by elements withcontinuously increasing or decreasing concentrationsrelated to pedogenetical development of the catchmentsoil. In the case of Hg, Pb and Cd, however,accumulation rates increased faster at the surface thanis simply accounted for by changes in total sedimentationrates. For Cu, Cr, Ni and Zn, concentrationsincreased over the past 150 years, but there were noindications of a significant addition due to atmosphericdeposition. These elements had more variableconcentrations before the mid nineteenth century thanafter, as did elements that are often used fornormalization. These findings suggest that lakesediments may not properly reflect the history of atmospheric metal deposition in remote areas.

    Persistent hazardous waste and the quest towards a circular economy: the example of arsenic in Chromated Copper Arsenate-treated wood2017Ingår i: Journal of Industrial Ecology, ISSN 1088-1980, E-ISSN 1530-9290, Vol. 21, nr 3, s. 689-699Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The importance of a circular economy is today widely accepted and advocated, but among the challenges in achieving this, we find difficulties in the implementation of legislation and policies designed to control various waste streams from society. The example used in this article is wood that has been treated with chromated copper arsenate (CCA), which, in Sweden, has been covered by the rules for hazardous waste since 2002. One year later, in 2003, a survey showed that only 42% to 50% of the expected amount of CCA waste could be traced to the public waste management system. An updated material flow analysis for 2010 revealed that the figure had increased to 73%, whereas the fraction of correctly treated CCA wood waste had increased from 11% to 35%. However, almost one third of the expected volume was still not tracable, and half of the amount that was correctly submitted was incinerated together with nontoxic waste fractions. This results in, for example, arsenic contamination of slag and fly ashes that prevents the further use of these residue products. So, despite legislative instruments, there is still an urgent need for an improved collection of hazardous wood waste, as well as better routines for identifying hazardous flows and separating them from nonhazardous ones. For a circular economy to be achievable, a key priority should be to reduce the gap between intended directions and legislation, on one hand, and activities in practice on the other.

    Health risks from drinking water around contaminated glassworks sites2014Ingår i: ABSTRACTS OF SCIENTIFIC CONTRIBUTIONS 2014 NGL ANNUAL SCIENCE MEETING: Oskarshamn, Sweden 3-4 of November 2014, 2014Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    In Kalmar and Kronoberg Counties, there are numerous glassworks areas with high levels of arsenic, lead and cadmium in soil and groundwater. To investigate whether metals are leached into drinking water to such an extent that it may constitute a health risk for local inhabitants, 57 water samples were collected from private wells within a radius of 500 m from eight glassworks sites. The results show that concentrations are well below drinking-water criteria in most samples; only three Pb- and one Asanalysis were above these limits. What these results indicate, is that metals that leach from glass waste and can be detected in groundwater around landfill areas, are effectively immobilized as the groundwater flows towards areas where the pollution level of the surrounding solid phase decreases. There is thus reason to focus further efforts toward understanding these sorption mechanisms, in order to take them into account in future risk assessments.

    The risk with overestimating the risk – the example of metal exposure via drinking water around contaminated glassworks sites2015Ingår i: The Future of Risk Analysis in the Nordic Contries: 1st Nordic Chapter Risk Conference, Lund, Sweden, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Large amounts of waste material with high concentrations of various metal(loid)s are common features at old glassworks sites in southeastern Sweden. As epidemiological data indicates increased health risks for local residents around these sites, questions about how exposure occurs have been raised. One important step in assessing site-specific total exposure is to quantify exposure via intake of drinking water, and the critical variable to determine here is the metal concentration in the water to be consumed. In many routine risk assessments this is, despite well-known uncertainties, done by applying conservative and simplified transport models that simulate concentrations in water abstraction wells at certain distances from the source of contamination. To assess the accuracy of such an approch, we used a probabilistic method to simulate metal concentrations in drinking water within 500 m distance from 10 heavily contaminated glassworks sites, by applying the transport equations of the Swedish EPA generic risk assessment model. Exposure was then calculated. When concentrations in drinking water were calculated using this modelling approach, the resulting exposure estimates indicated that as much as 100% of the local residents with private wells may reach a daily intake above applicable toxicological reference values. However, when assessing the risk from measured concentrations in household drinking water instead, not even the 95th percentile of the population reached the toxicological limit. It hence appears as if metals are efficiently sorbed to the solid matrix of the soil at these sites, leaving the drinking water with concentrations well below drinking water criteria. For the average risk assessor working with contaminated sites, who often lacks training in hydrogeochemistry, the contradictory results highlight the need of more realistic generic models to be used in routine assessments of water contamination and exposure via consumption of drinking water.

    Challenges in assessing the health risks of consuming vegetables in metal-contaminated environments2018Ingår i: Environment International, ISSN 0160-4120, E-ISSN 1873-6750, Vol. 113, s. 269-280Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A great deal of research has been devoted to the characterization of metal exposure due to the consumption of vegetables from urban or industrialized areas. It may seem comforting that concentrations in crops, as well as estimated exposure levels, are often found to be below permissible limits. However, we show that even a moderate increase in metal accumulation in crops may result in a significant increase in exposure. We also highlight the importance of assessing exposure levels in relation to a regional baseline. We have analyzed metal (Pb, Cd, As) concentrations in nearly 700 samples from 23 different vegetables, fruits, berries and mushrooms, collected near 21 highly contaminated industrial sites and from reference sites. Metal concentrations generally complied with permissible levels in commercial food and only Pb showed overall higher concentrations around the contaminated sites. Nevertheless, probabilistic exposure assessments revealed that the exposure to all three metals was significantly higher in the population residing around the contaminated sites, for both low-, medianand high consumers. The exposure was about twice as high for Pb and Cd, and four to six times as high for As. Since vegetable consumption alone did not result in exposure above tolerable intakes, it would have been easy to conclude that there is no risk associated with consuming vegetables grown near the contaminated sites. However, when the increase in exposure is quantified, its potential significance is harder to dismiss - especially when considering that exposure via other routes may be elevated in a similar way.

    Metal uptake by homegrown vegetables: the relative importance in human health risk assessments at contaminated sites2015Ingår i: Environmental Research, ISSN 0013-9351, E-ISSN 1096-0953, Vol. 138, s. 181-190Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Risk assessments of contaminated land often involve the use of generic bioconcentration factors (BCFs),which express contaminant concentrations in edible plant parts as a function of the concentration in soil,in order to assess the risks associated with consumption of homegrown vegetables. This study aimed toquantify variability in BCFs and evaluate the implications of this variability for human exposure as-sessments, focusing on cadmium (Cd) and lead (Pb) in lettuce and potatoes sampled around 22 con-taminated glassworks sites. In addition, risks associated with measured Cd and Pb concentrations in soiland vegetable samples were characterized and a probabilistic exposure assessment was conducted toestimate the likelihood of local residents exceeding tolerable daily intakes. The results show that con-centrations in vegetables were only moderately elevated despite high concentrations in soil, and mostsamples complied with applicable foodstuff legislation. Still, the daily intake of Cd (but not Pb) wasassessed to exceed toxicological thresholds for about afifth of the study population. Bioconcentrationfactors were found to vary more than indicated by previous studies, but decreasing BCFs with increasingmetal concentrations in the soil can explain why the calculated exposure is only moderately affected bythe choice of BCF value when generic soil guideline values are exceeded and the risk may be un-acceptable.

    The risk of overestimating the risk-metal leaching to groundwater near contaminated glass waste deposits and exposure via drinking water2016Ingår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 566, s. 1420-1431Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study investigates metal contamination patterns and exposure to Sb, As, Ba, Cd and Pb via intake of drinking water in a region in southeastern Sweden where the production of artistic glass has resulted in a large number of contaminated sites. Despite high total concentrations of metals in soil and groundwater at the glassworks sites properties, all drinking water samples from households with private wells, located at a 30-640 m distance from a glassworks site, were below drinking water criteria from the WHO for Sb, As, Ba and Cd. A few drinking water samples showed concentrations of Pb above the WHO guideline, but As was the only element found in concentrations that could result in human exposure near toxicological reference values. An efficient retention of metals in the natural soil close to the source areas, which results in a moderate impact on local drinking water, is implied. Firstly, by the lack of significant difference in metal concentrations when comparing households located upstream and downstream of the main waste deposits, and secondly, by the lack of correlation between the metal concentration in drinking water and distance to the nearest glassworks site. However, elevated Pb and Cd concentrations in drinking water around glassworks sites when compared to regional groundwater indicate that diffuse contamination of the soils found outside the glassworks properties, and not only the glass waste landfills, may have a significant impact on groundwater quality. We further demonstrate that different mobilization patterns apply to different metals. Regarding the need to use reliable data to assess drinking water contamination and human exposure, we finally show that the conservative modelling approaches that are frequently used in routine risk assessments may result in exposure estimates many times higher than those based on measured concentrations in the drinking water that is actually being used for consumption.

    High metal reactivity and environmental risks at a site contaminated by glass waste2016Ingår i: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298, Vol. 154, s. 434-443Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study addresses the reactivity and risks of metals (Ba, Cd, Co, Cr, Cu, Ni, Pb, Zn, As and Sb) at a Swedish site with large glass waste deposits. Old glassworks sites typically have high total metal concentrations, but as the metals are mainly bound within the glass waste and considered relatively inert, environmental investigations at these kinds of sites are limited. In this study, soil and landfill samples were subjected to a sequential chemical extraction procedure. Data from batch leaching tests and groundwater upstream and downstream of the waste deposits were also interpreted. The sequential extraction revealed that metals in <2 mm soil/waste samples were largely associated with geochemically active fractions, indicating that metals are released from pristine glass and subsequently largely retained in the surrounding soil and/or on secondary mineral coatings on fine glass particles. From the approximately 12,000 m(3) of coarse glass waste at the site, almost 4000 kg of Pb is estimated to have been lost through corrosion, which, however, corresponds to only a small portion of the total amount of Pb in the waste. Metal sorption within the waste deposits or in underlying soil layers is supported by fairly low metal concentrations in groundwater. However, elevated concentrations in downstream groundwater and in leachates of batch leaching tests were observed for several metals, indicating on-going leaching. Taken together, the high metal concentrations in geochemically active forms and the high amounts of as yet uncorroded metal-rich glass, indicate considerable risks to human health and the environment.

    Biogeochemical Transformation Pathways through the Land-water Geosphere2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Water on land undergoes and participates in many biogeochemical exchanges and changes. A bits-and-pieces approach to these may miss essential aspects of change propagation and transformation by land-water through different segments of the Earth system. This paper proposes a conceptualization of the entire land-water geosphere as a scale-free catchment-wise organised system (Figure 1), emphasizing four key new system aspects compared to traditional hydrosphere/water cycle view: i) distinction of coastal divergent in addition to traditional convergent catchments; ii) physical and social-ecological system coupling through four main nodal zones/interfaces (surface, subsurface, coastal, observation); iii) flow-transport pathways as system coupling agents; iv) multiple interactions with the anthroposphere as integral system parts. Utilizing this conceptualization, we identify distinct patterns of direct anthropogenic change in large-scale water and waterborne nutrient fluxes, emerging across different parts of the world. In general, its embedment directly in the anthroposphere/technosphere makes land-water a key geosphere for understanding and monitoring human-driven biogeochemical changes. Further progress in system-level understanding of such changes requires studies of land-water as a continuous yet structured geosphere following the proposed spatiotemporal pathways of change propagation-transformation.

    Needs and means to advance science, policy and management understanding of the freshwater system: A synthesis report2015Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Fragmented and inconsistent understanding of the freshwater system limits our ability to achieve water security and sustainability under the human-driven changes occurring in the Anthropocene. To advance system-level understanding of freshwater, gaps and inconsistencies in knowledge, data, representations and links of processes and subsystems need to be identified and bridged under consideration of the freshwater system as a continuous whole. 

    Based on such identification, a freshwater system conceptualization is developed in this report, which emphasizes four essential, yet often neglected system aspects:

    i) Distinction of coastal divergent catchments.

    ii) Four main zones (surface, subsurface, coastal, observation) of different types of freshwater change.

    iii) Water pathways as system-coupling agents that link and partition water change among the four change zones.

    iv) Direct interactions with the anthroposphere as integral system pathways across the change zones.

    We explain and exemplify some key implications of these aspects, identifying in the process also distinct patterns of human-driven changes in large-scale water fluxes and nutrient loads.

    The present conceptualization provides a basis for common inter- and trans-disciplinary understanding and systematic characterization of the freshwater system function and its changes, and of approaches to their modeling and monitoring. This can be viewed and used as a unifying checklist that can advance science, policy and management of freshwater and related environmental changes across various scales and world regions.

    Perception of uncertainties and quality in risk assessments by people working with risk assessments2013Ingår i: Abstracts of the 2013 Conference of the International Society of Environmental Epidemiology (ISEE), the International Society of Exposure Science (ISES), and the International Society of Indoor Air Quality and Climate (ISIAQ)., 2013, s. Abstract Number : 3978-Konferensbidrag (Refereegranskat)
    Abstract [en]

    Background About 80,000 possible contaminated sites have been identified in Sweden. Assessing the risk posed by these sites and, if necessary, remediating the soil is associated with high costs. It is thus important that these assessments are reliable. A problem with current methods is that uncertainty and variability are often not accounted for. Different individuals have different physiology and behaviour and soil composition differs at various sites which can be considered in probabilistic methods. This requires tools that are user-friendly and cost and time-efficient. Information about the perception of risk assessments, uncertainty and tools wanted by people working with risk assessments is therefore needed.

    Aims The aim of this study is to investigate whether people working with risk assessments in practice find that these assessments are of sufficient quality, whether it is important to consider uncertainty and variability and which tools they may need to be able to consider these questions.

    Methods A questionnaire was sent to people working with the risk assessment of contaminated sites at government authorities and consultancies in Sweden. Results The data collected suggest that the majority of respondents find that risk assessment quality in general would need to be improved. Important factors to achieve this include a greater knowledge of the individuals involved in risk assessments, more financial resources, greater knowledge in form of new research and more time. The respondents also find it very important to characterize both uncertainty and variability, and to do this several respondents want more tools such as literature and databases with information about critical exposure factors and manuals.

    Conclusions

    According to personnel involved in the risk assessment of contaminated sites, the quality of the assessment should be enhanced and different tools would be useful to facilitate the characterization of uncertainty and variability.

    Consumption of vegetables and risk perception at contaminated glass works sites in Sweden2013Ingår i: Abstracts of the 2013 Conference of the International Society of Environmental Epidemiology (ISEE), the International Society of Exposure Science (ISES), and the International Society of Indoor Air Quality and Climate (ISIAQ)., 2013, s. Abstract Number: 3980-Konferensbidrag (Refereegranskat)
    Abstract [en]

    Background Glass has been produced since the 18th century in Kalmar and Kronoberg counties in an area called the Kingdom of Crystal. The production of glass has been associated with high levels of heavy metals in the soil. The most critical exposure pathways for metals are oral intake of soil, consumption of water and home-produced vegetables. The consumption of home-produced vegetables in particular is a highly site-specific exposure pathway and is therefore of interest to investigate in this geographic area.

    Aims The study aims to investigate to what extent home-produced vegetables are consumed by people living near glass work industries as well as their perception of environmental and health risks and the authorities’ risk communication.

    Methods A questionnaire including questions about personal factors, consumption of vegetables and fruit as well as the perception of risks and risk communication was sent to 300 randomly selected individuals living in areas close to glass works. Results A majority of those questioned, 87%, consume vegetables or fruit from their own garden sometime during the year and more than half of the respondents eat these food items on a regular basis or several times a year. Just over 40% are concerned about that the fruit or vegetables from their own garden may be contaminated with pollutants from the glass works, but an even greater number are concerned that pollution from glass works will affect their health or the environment in general. More than half of the respondents would like to have more information about environmental and health risks.

    Conclusions

    Home-produced vegetables are frequently consumed in areas around glass work industries. Many residents are at the same time concerned and request more information about possible risks. Site-specific studies including quantities and types of vegetables ingested as well as contamination levels are needed to investigate if the exposure is actually of concern.

    Assessing toxicity of metal contaminated soil from glassworks sites with a battery of biotests2018Ingår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 613, s. 30-38Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The present study addresses toxicological properties of metal contaminated soils, using glassworks sites in south-easternl Sweden as study objects. Soil from five selected glassworks sites as well as from nearby reference areas were analysed for total and water-soluble metal concentrations and general geochemical parameters. A battery of biotests was then applied to assess the toxicity of the glassworks soil environments: a test of phytotoxicity with garden cress (Lepidium sativum); the BioTox(TM) test for toxicity to bacteria using Vibrio fischeri; and analyses of abundancies and biomass of nematodes and enchytraeids. The glassworks-and reference areas were comparable with respect to pH and the content of organic matter and nutrients (C, N, P), but total metal concentrations (Pb, As, Ba, Cd and Zn) were significantly higher at the former sites. Higher metal concentrations in the water-soluble fraction were also observed, even though these concentrations were low compared to the total ones. Nevertheless, toxicity of the glassworks soils was not detected by the two ex situ tests; inhibition of light emission by V. fischeri could not be seen, nor was an effect seen on the growth of L. sativum. A decrease in enchytraeid and nematode abundance and biomass was, however, observed for the landfill soils as compared to reference soils, implying in situ toxicity to soil-inhabiting organisms. The confirmation of in situ bioavailability and negative effects motivates additional studies of the risk posed to humans of the glassworks villages. (C) 2017 Published by Elsevier B.V.

    Environmental toxicity of glassworks landfill soils2016Ingår i: Linnaeus ECO-TECH 2016: Book of Abstracts : The 10th International Conference on Establishment of Cooperation between Companies and Institutions in the Nordic Countries, the Baltic Sea Region and the World. / [ed] Stina Alriksson, Jelena Lundström, William Hogland, Linnaeus University Press, 2016, s. 241-242Konferensbidrag (Refereegranskat)
    Abstract [en]

    Following over 200 years of industrialization, soil contamination is a widespread problem in many countries. Contaminants, especially heavy metals and persistent organic compounds, can still be found at high concentrations decades after the emissions have ceased. One important part of this industrial heritage is the heavy metal contamination of soil and landfills around glass factories, with complex relationships between contaminants, the natural hydrogeochemical environment and biota. In southeastern Sweden lies the so called “Kingdom of Crystal”, with a long tradition of artistic glass production and elevated concentrations of a range of metals found in soil and landfills of the glassworks sites. Because high total concentrations may not always translate into a high mobility, bioavailability, and toxicity, research on biological effects has been deemed necessary to delineate the severity of contamination.

    For the present study, soil samples from landfills and control areas were collected at five glassworks in the Kingdom of Crystal (Bergdala, Målerås, Kosta, Johansfors and Orrefors). Each landfill site was heavily contaminated with various metals. As, Ba, Cd, Pb, Sb and Zn were the major contaminants, exceeding the guideline values of Swedish legislation. Total concentrations were found in the range 64-7800 mg As kg-1, 30- 600 mg Ba kg-1, 0.16- 3 mg Cd kg-1, 160-38000 mg Pb kg-1, 0.40-56 mg Sb kg-1, and 45-1100 mg Zn kg-1. To test for biotoxicity, a battery of tests with species of varying sensitivities and exposure pathways were applied. Evaluation of plant toxicity to Lepidium sativum demonstrated the lack of difference between biomass production between the soils from contaminated landfill sites and control areas. Similarly, elutriates from both metal contaminated and reference soils implied low toxicity to the photobacterium Vibrio fisheri. However, significant reduction in the numbers and biomass of enchytraeids was observed in the landfill sites of Bergdala, Kosta, Johansfors and Orrefors. Also the numbers of nematodes tended to be reduced in landfill sites. Altogether, the obtained results provide a better understanding of the complex historical contamination by evaluating biological responses at different levels.

    Characterization and toxicity of hazardous wastes from an old Swedish glasswork dumpIngår i: Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    More than 34 old glasswork sites in the southeastern part of Sweden pose a permanent threat to human and environmental health due to the presence of toxic metals in open dumps with glass waste. The possibility of leaching of metals from different fractions of the disposed waste needed to be assessed. In the present investigation, leachate from fine fraction (soil plus glass particles < 2 mm) was characterized as following: pH (7.3), TOC (< 2%), organic content (4.4%), moisture content (9.7), COD (163 mg/kg) and trace elements content, being the values in accordance to the Swedish guidelines for landfilling of inert materials. However, very high metals content was found in the fine fraction as well as in all colors of the glass fraction (≥ 2 mm), whose values were compatible to hazardous waste landfill class. Tests with Lepidium sativum growing in the fine fraction as substrate revealed chronic toxicity expressed as inhibition of root biomass growth in 11 out of 15 samples. Additionally, leachate from fine fractions posed acute toxicity to genetically modified E. coli (Toxi-Chromotest). This study highlights the importance of combining physicochemical characterization with toxicity tests for both solid waste and leachate obtained from different waste fractions for proper hazardousness assessment supporting decision making on remediation demands.

    Physicochemical and toxicological characterization of hazardous wastes from an oldglasswork dump at southeastern part of Sweden2019Ingår i: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    More than 34 old glasswork sites in the southeastern part of Sweden pose a permanent threat to human and environmental health due to the presence of toxic trace elements in open dumps with glass waste. The possibility of leaching of trace elements from different fractions of the disposed waste needed to be assessed. In the present investigation, leachate from a mixture of soil and waste glass of particle sizes of less than 2mm (given the name fine fraction) was characterized by analyzing the pH (7.3), total organic content (TOC<2%), organic matter content (4.4%), moisture content (9.7%), chemical oxygen demand (COD, 163mg/kg) and trace elements content, being the values in accordance to the Swedish guidelines for landfilling of inert materials. However, very high trace elements content was found in the fine fraction as well as in all colors of waste glass, whose values were compatible to hazardous waste landfill class. Tests with Lepidium sativum growing in the fine fraction as substrate revealed chronic toxicity expressed as inhibition of root biomass growth in 11 out of 15 samples. Additionally, leachate from fine fractions posed acute toxicity to genetically modified E. coli (Toxi-Chromotest). This study highlights the importance of combining physicochemical characterization with toxicity tests for both solid waste and leachate obtained from different waste fractions for proper hazardousness assessment supporting decision making on remediation demands.

    Fractionation of Pb and Cu in the fine fraction (< 10 mm) of waste excavated from a municipal landfill2017Ingår i: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 35, nr 11, s. 1175-1182Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The fractionation of metals in the fine fraction (<10 mm) of excavated waste from an Estonian landfill was carried out to evaluate the metal (Pb and Cu) contents and their potential towards not only mobility but also possibilities of recovery/extraction. The fractionation followed the BCR (Community Bureau of Reference) sequential extraction, and the exchangeable (F1), reducible (F2), oxidizable (F3) and residual fractions were determined. The results showed that Pb was highly associated with the reducible (F2) and oxidizable (F3) fractions, suggesting the potential mobility of this metal mainly when in contact with oxygen, despite the low association with the exchangeable fraction (F1). Cu has also shown the potential for mobility when in contact with oxygen, since high associations with the oxidizable fraction (F3) were observed. On the other hand, the mobility of metals in excavated waste can be seen as beneficial considering the circular economy and recovery of such valuables back into the economy. To conclude, not only the total concentration of metals but also a better understanding of fractionation and in which form metals are bound is very important to bring information on how to manage the fine fraction from excavated waste both in terms of environmental impacts and also recovery of such valuables in the economy.

    Effect of Medicago sativa L. and compost on organic and inorganic pollutant removal from a mixed contaminated soil and risk assessment using ecotoxicological tests2016Ingår i: International journal of phytoremediation, ISSN 1522-6514, E-ISSN 1549-7879, Vol. 18, nr 11, s. 1136-1147Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Several Gentle Remediation Options (GRO), e.g. plant-based options (phytoremediation), singly and combined with soil amendments, can be simultaneously efficient for degrading organic pollutants and either stabilizing or extracting trace elements (TE). Here, a 5-month greenhouse trial was performed to test the efficiency of Medicago sativa L., singly and combined with a compost addition (30% w/w), to treat soils contaminated by petroleum hydrocarbons (PHC), Co and Pb collected at an auto scrap yard. After five months, total soil Pb significantly decreased in the compost-amended soil planted with M. sativa, but not total soil Co. Compost incorporation into the soil promoted PHC degradation, M. sativa growth and survival, and shoot Pb concentrations (3.8 mg/kg DW). Residual risk assessment after the phytoremediation trial showed a positive effect of compost amendment on plant growth and earthworm development. The O2 uptake by soil microorganisms was lower in the compost-amended soil, suggesting a decrease in microbial activity. This study underlined the benefits of the phytoremediation option based on M. sativa cultivation and compost amendment for remediating PHC and Pb contaminated soils.

    Increased Cancer Incidence in the Local Population Around Metal-Contaminated Glassworks Sites2017Ingår i: Journal of Occupational and Environmental Medicine, ISSN 1076-2752, E-ISSN 1536-5948, Vol. 59, nr 5, s. E84-E90Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The aim of this study was to examine mortality causes and cancer incidence in a population cohort that have resided in close proximity to highly metal-contaminated sources, characterized by contamination of, in particular, arsenic (As), cadmium (Cd), and lead (Pb). Methods: Data from Swedish registers were used to calculate standardized mortality and cancer incidence ratios. An attempt to relate cancer incidence to metal contamination levels was made. Results: Significantly elevated cancer incidences were observed for overall malignant cancers in both genders, cancer in the digestive system, including colon, rectum, and pancreas, and cancers in prostate among men. Dose-response relationships between Cd and Pb levels in soil and cancer risks were found. Conclusions: Cancer observations made, together with previous studies of metal uptake in local vegetables, may imply that exposure to local residents have occurred primarily via oral intake of locally produced foodstuffs.

    Coloured Plastic Bags for Kerbside Collection of Waste from Households - To Improve Waste Recycling2019Ingår i: Recycling, E-ISSN 2313-4321, Vol. 4, nr 2, s. 1-10Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Today, considerable amounts of resources are landfilled or incinerated, and recyclable materials such as metal, glass, plastic, and paper are disposed of as residual waste instead of being sorted into recyclable fractions. Recycling is one way of transitioning towards a circular economy and a more resource-efficient society. However, in many older cities there is insufficient space for waste bins, which makes waste sorting difficult. The aim of the study was to test how the introduction of a new kerbside collection system, using different-coloured plastic bags, would influence the amounts of residual waste and separately collected food waste. Coloured plastic bags were introduced in an old city centre in Kalmar, in the southeast of Sweden. This type of kerbside collection was applied to 38 apartments with a total of 87 residents for four weeks. Results show that residual waste decreased directly by 15 percent and the collected amount of food waste increased directly by 35 percent. The residents perceived that the sorting system facilitated sorting and that the sorting of recyclable materials increased. Kerbside collection, close to properties, seemed to be an important factor in reducing the amount of residual waste, leading to increased sorting, and hence improved recycling.

    The variability in bioconcentration factors and the importance of bioconcentration factors in probabilistic risk assessments2015Ingår i: The Future of Risk Analysis in the Nordic Countries: Lund, Sweden, 16-17 November 2015, 2015Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Bioconcentration factors (BCFs) express contaminant concentration in edible plants as a function of the concentration in soil. Routine risk assessments rarely include site-specific analyses of contaminants in vegetables. Instead a common procedure is to use generic BCFs which are uncertain for several reasons. There is a natural variability in metal uptake in plants. The uptake varies between crops, and depends largely on both geochemical and hydrological conditions of the soil. Despite this many risk assessments in practice use BCFs, without taking into account the influence of geochemical factors.

    A study at the Linnaeus University aimed to quantify the variability in BCFs and to evaluate the implication of this variability for human exposure assessments. Potatoes and lettuce with corresponding soil samples were collected from contaminated glasswork sites and analyzed for cadmium and lead.

    The results indicated that the variability in BCF values was greater than indicated by previous studies (having a larger possible min–max span). The importance of this variability in exposure assessments was, however, most evident at low soil metal concentrations. At high concentrations, BCFs were lower and the variability in calculated exposure was mainly dependent on the soil contamination level. Although the conclusion is that the BCFs is of relatively little importance compared to the concentration in soil, the BCFs is still of equal or greater importance than the other exposure factors included in the calculation of exposure via vegetable consumption. The lower BCFs at high contamination levels also highlight the importance of selecting BCFs that are characterized for relevant contamination levels.

    Much of the variability described in this study may, however, reflect the results of a BCF characterization approach that is uncertain. Thus, BCF characterizations using more precise methods should be prioritized in future studies.

    Heavy metal transport at a contaminated glassworks site in southeast Sweden.2016Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Heavy metal transport at a contaminated glassworks site in southeast Sweden.

    In the “Kingdom of crystal” in southeastern Sweden there are a large number of glassworks sites, which are characterized by high pollution levels of a number of metal contaminants. At Pukeberg glassworks site, which is the focus of this study, As, Ba, Cd, Pb, Sb and Zn are present in significantly elevated levels. For this study, which aim is to characterize the release of metals from the glass waste into soil water and groundwater, 54 soil samples from both saturated and unsaturated zone were gathered. Soil water were sampled from lysimeters installed on the landfill area and groundwater were collected from sampling tubes located upstream, at and downstream of the landfill area. The collected samples were analyzed and distribution coefficients (Kd) were calculated as the ratio of the average pseudo-total metal concentrations in soil (from the landfill site with visible glass) to the average dissolved metal concentrations in soil water to describe the leachability of the metal(loid) in the wastes.

    High concentrations of metal(loid)s were found in soil water samples at the landfill (collected at 30 and 60 cm depth), indicating that metals are leached from the solid waste materials. The distribution coefficients indicate the highest leachability for Ba (Kd= 150 l/kg) and Sb (Kd= 190 l/kg), a moderately leachability for Cd (Kd= 860 l/kg) and Zn (Kd= 500) and the lowest leachability for As and Pb (Kd= 6000 and 16000 respectively). Examining the soil profiles shows that the metal concentrations are considerable lower when there are no visible glass wastes in the soil, which implies that the majority of leached metals are retained in the waste pile.  Significant sorption is also suggested by the low concentrations measured in the groundwater samples. The theoretical dilution of the catchment area alone, cannot explain the decrease in metal concentration between the soil water and the groundwater. With exception for Sb, that seems to move relatively unrestrained from the unsaturated zone to the saturated zone.

    The results indicate that there are sorption processes involved, preventing or slowing down the transport of the investigated metals through the unsaturated zone. The responsible geochemical processes need to be established before assessing remediation strategies for the contaminated area, as it gives information on the factors controlling the metal leaching.

    Metal solubility and transport at a contaminated landfill site – From the source zone into the groundwater2019Ingår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 668, s. 1064-1076Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Risks associated with metal contaminated sites are tightly linked to material leachability and contaminant mobility. In this study, metal solubility and transport were characterized within a glass waste landfill through i) lysimeter-collection of pore water and standardized batch leaching tests, ii) soil profiles extending from the landfill surface, through unsaturated soil underneath, and into the groundwater zone, and iii) groundwater samples upstream, at, and downstream of the landfill. The soil analyzes targeted both pseudo-total and geochemically active concentrations of contaminant metals (As, Cd, Pb, Sb) and basic soil geochemistry (pH, org. C, Fe,Mn). Water samples were analyzed for dissolved, colloid-bound and particulate metals, and speciation modelling of the aqueous phase was conducted. The results revealed a highly contaminated system, with mean metal concentrationsin the waste zone between 90 and 250 times the regional background levels. Despite severe contamination of the waste zone and high geochemically active fractions (80–100%) of all contaminant metals as well as elevated concentrations in landfill pore water, the concentrations of Cd and Pb decrease abruptly at the transition between landfill and underlying natural soil and no indication of groundwater contamination was found. The efficient cation retention is likely due to the high pH. However, the sorption of As and Sb is weaker at such high pH,which explains their higher mobility from the pore water zone into groundwater. The field soil:solution for Pb, ranging from 140 to 2,900,000 l kg−1), despite little variability in basic geochemical variables, which we suggest is due to waste material heterogeneity.

    An assessment of health risks associated with arsenic exposure via consumption of homegrown vegetables near contaminated glassworks sites2015Ingår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 536, s. 189-197Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The health risk posed by arsenic in vegetables grown in private gardens near 22 contaminated glassworks sites was investigated in this study. Firstly, vegetable (lettuce and potato) and soil samples were collected and arsenic concentrations measured to characterize the arsenic uptake in the selected crops. Secondly, a probabilistic exposure assessment was conducted to estimate the average daily intake (ADI(veg)), which was then evaluated against toxicological reference values by the calculation of hazard quotients (HQs) and cancer risks (CRs). The results show that elevated arsenic concentrations in residential garden soils are mirrored by elevated concentrations in vegetables, and that consumption of these vegetables alone may result in an unacceptable cancer risk; the calculated reasonable maximum exposure, for example, corresponded to a cancer incidence 20 times higher than the stated tolerance limit. However, the characterization of risk depends to a great extent on which toxicological reference value is used for comparison, as well as how the exposure is determined. Based on the assumptions made in the present study, the threshold levels for chronic non-carcinogenic or acute effects were not exceeded, but the cancer risks indicated highlight the need for further exposure studies, as dietary intake involves more than just homegrown vegetables and total exposure is a function of more than just one exposure pathway. In addition, glassworks sites - and contaminated sites in general - contain multiple contaminants, affecting the final and total risk.

    Sources, transport and sinks of beryllium in a coastal landscape affected by acidic soils2018Ingår i: Geochimica et Cosmochimica Acta, ISSN 0016-7037, E-ISSN 1872-9533, Vol. 232, s. 288-302Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Beryllium (Be) sources, transport and sinks were studied in a coastal landscape where acidic soils (acid sulfate soils) have developed after drainage of fine-grained sulfide-bearing sediments. The study included the determination of total abundance and speciation of Be in a variety of solid and aqueous materials in both the terrestrial and estuarine parts of the landscape. A major feature was that despite normal (background) Be concentration in the sulfide-bearing sediments, the Be leaching from these sediments after O2-exposure and acid sulfate soil development were extensive, with concentrations up to 76 μg L−1 in soil water, 39 μg L−1 in runoff and 12 μg L−1 in low-order streams. These high Be concentrations were mainly in the solution form (i.e., passing a 1 kilodalton filter) and modelled to be dominated by free Be2+. The extensive Be release within, and leaching from the acid sulfate soils was controlled by pH, with a critical value of 4.0 below which the Be concentrations increased strongly. Although plagioclase and mica were most likely the main carriers of Be within these soils, it is suggested that other minerals such as Be hydroxides, Al hydroxides carrying Be, and Be sulfides are the main contributors of the abundance of dissolved Be in the acidic waters. When the acidic and Be-rich creek water was neutralized in the estuary of relatively low salinity, the dominating solution form of Be was removed by transformation to particles, reflected in the suspended particulate matter that had hydroxylamine hydrochloride extractable Be up to 17 mg kg−1 and ammonium acetate EDTA extractable Be up to 4 mg kg−1. In corresponding pristine materials (parent material of the acid sulfate soils) in the catchment, the median Be extractability with these reagents were only 0.3 and 0.05 mg kg−1, respectively. As the Be-rich suspended particulate matter ultimately became benthic sediment, the Be was preserved in terms of total concentrations but underwent to some extent changes in speciation, including release from hydroxides and concomitant scavenging by organic matter and particle surfaces.
