ANTHROPOGENIC POLLUTION OF WATER FACILITIES AND ITS ENVIRONMENTAL AND ECONOMIC CONSEQUENCES (ON THE EXAMPLE OF R. KONOPLYANKO)

Experimental studies to determine the chronic toxicity of water samples and bottom sediments taken in the control areas of water bodies — return water intakes are presented. Biotesting of water samples was performed using zooplankton (Ceriodaphnia affinis Lilljeborg) and zoobenthos of insect larvae (Chironomus dorsalis Meig.) As test objects for food organisms for fish. The methodological approach is chosen in the paper to calculate the losses caused to fisheries due to the reduction of the natural forage base for ichthyofauna, ie by the criterion of reducing fish productivity.
