A linear dependence between COD and inhibition determined by means of Vibrio fischeri was established. In 30 days following sampling organic matter was degraded and the value of inhibition fell from 80 % to 27.67 %. This value corresponds to the real impact of micropollutants (risk elements, organic micropollutants) on inhibition. The content of risk elements in municipal waste water implies that the values are significantly higher than EC50 defined for Daphnia magna. Risk element ecotoxicity is affected by the form of occurrence and it is thus probable that there are risk elements predominantly in the form of complexes in sewage water.324202132420213942https://www.naun.org/main/NAUN/energyenvironment/2021/a142011-007(2021).pdf10.46300/91012.2021.15.7https://www.naun.org/main/NAUN/energyenvironment/2021/a142011-007(2021).pdf10.1016/j.trac.2008.09.018M.
