The analysis of the impact of PCC “Rokita” chemical industry on the natural environment has been studied. Samples of water, soil and sediment taken nearby industry were analyzed with ecotoxicological tests.. We used Avena sativa for study the impact of industry on producers and to evaluate soil quality. Additionally the commercial test, Phytotoxkit, test was conducted. Water quality was assessed using Tubifex tubifex and Daphnia magna/ Sediment’s quality was assessed with the application of Ostracodtoxkit F test (Heterocypris incongruens). Conducted ecotoxicological tests proved that the studied area surrounding PCC “Rokita” is still contaminated with organic toxic compounds we observed mortality in water and soil of organisms tested. The fighest impact of toxicants was recorded for sediments suggesting accumulation of toxicants over many years.
