Ecotoxicological evaluation of river sediments in selected localities of the Odra river basin

The paper deals with the issue of pollution of river (bottom) sediments in the Odra river basin, which is located in one of the most anthropogenically polluted areas of the Czech Republic. The presented results are based on the evaluation of river sediments collected on eight selected profiles of water bodies belonging to the Odra river basin using a battery of five ecotoxicological tests including indicator organisms of different trophic levels.
