Popis: Kyiv is Ukraine’s capital and largest city. Home to 3 million people, this area has a rich history of agriculture and industry. The Dnieper River is Ukraine’s largest river and it passes through the center of Kyiv. Little information on emerging and legacy compounds or their toxicity exists for this area. Water and biota were sampled for PAHs, PCBs, metals and emerging contaminants including pharmaceuticals, personal care products and newer synthetic pesticides. The effects of surface waters in the Dnieper were evaluated using the Ames, chronic and acute daphnia and a ciliate (Colpoda stennii) assay. Elevated concentrations of legacy contaminants were found in fish samples indicating that these compounds are bioavailable. Concentrations of legacy and emerging contaminants were found in seven stations near the municipal water treatment plant (MWTP) and receiving waters of the Dnieper River. The MWTP appeared to remove some of the emerging contaminants, however the legacy compounds (PCBs and PAHs) were not affected by the MWTP and appeared to be more wide spread indicating a number of sources to the Dnieper River. Acute and chronic toxicity were associated with the influent and effluent of the MWRP, however mutagenicity was noted in surface waters throughout the Dnieper River including upstream of the MWTP. This study provides the first snapshot of possible human health and ecological risks associated with surface waters of the Dnieper. More research on seasonal changes and sources of toxicity, mutagenicity and contaminants would aid in completing a more comprehensive risk assessment of surface waters of the Dnieper River.
