Abstract [en]

Plants depend on nutrition uptake to live and thrive the same way humans depend on nutrition to live. They mainly ingest nutrients through the root system, but leafy plants also have the ability to ingest nutrients through foliar uptake from airborne deposition. Plants cannot differ nutrients from potential pollutants and might therefore also absorb pollutants. Urbanization and future food security are resulting in an urban farming trend in cities with anthropogenic air pollutions. This study is based in Malmö (Sweden) and investigates how airborne metal particles pollutes urban grown lettuce (Lactuca Sativa). The lettuce was grown in pre analyzed soil in the city on different altitudes and compared to lettuce with the same treatment on the countryside and additionally a controlled population grown in a lab environment. After a month the lettuce was harvested, and half of each plant was washed with deionized water and analyzed with the ICP-SFMS method. The results showed higher concentrations in the city compared to countryside and controlled population for most of the analyzed metals. It also showed significantly higher concentrations of Ba, Cd, Co, Mn, Ni, Pb and Zn in the city samples on ground level compared to balconies and roof tops. Washing the lettuce reduced parts of the detected metal concentrations with a variation between the analyzed metals where Al, Cr, Ni, Pb, Sb and Ti decreased the most.
