Abstract
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.

Summary
Along with the expanding range of new products, pollution produced by factories is growing which may have a negative impact on human and the entire biocenosis [1]. This impact comes from the interaction between contamination and the organism, population or biocenosis, which leads to the mortality of organisms, inhibition of growth or physiological functions. PCC "Rokita" was founded in 1946, in place of a former German factory, in order to produce various chemical products for war purposes. Due to its rapid development in terms of production and employment "Rokita" became one of the largest chemical plants in Poland in sixties of XX century. Environmental-friendly membrane technology was used, instead of the mercury installation which was harmful to the environment [3]
