Bioassays are valuable tools for environmental risk assessment, because they respond to bioavailable fraction of pollutants in water, sediments and soil. The phytotoxicity of water and sediments from Ignalina NPP area, Lithuania, industrial areas in Lithuania and Sweden, and a municipal landfill, and its potential impacts on receiving water was determined by Lepidium sativum, Spirodela polyrrhiza and Tradescantia clone 02. It was found that phytotoxicity of water and sediments from receiving water bodies fluctuated from non-toxic to extremely toxic. The results indicate that vascular plants sensitive tools for the toxicity determination in solid and liquid environment that can be successfully included in bioassays for the environmental risk assessment.
