Pesticides of modern classes in the water and bottom sediments of the Veselovsky Reservoir
The Veselovsky Reservoir is surrounded by agricultural land, where the use of pesticides is an integral part of the production cycle. By transferring with the air masses or seeping through the soil, pesticides can enter the water of the water bodies of fisheries importance, be deposited in bottom sediments, and negatively affect the vital activity of hydrobionts. The aim of the study was to detect the content of 20 active ingredients of the pesticides of modern classes most widely used in agriculture in the region, the half-life of which can exceed six months. It was found that the concentrations of pesticide active ingredients in the living environment of hydrobionts in the Veselovsky Reservoir are by more than an order of magnitude lower than the established maximum allowable concentrations (MAC), which indicates the relative safety of the environment for hydrobionts.
