Accumulation of heavy metals in fish from the perspective of regional features of accumulation of heavy metals in water areas, on the example of the Voronezh and Pskov regions

Abstract

The biogeochemical cycle of heavy metals in reservoirs depends on its hydrochemical parameters. In the Pskov region, iron and manganese adsorb copper, and fish accumulate copper, manganese and zinc. In the Voronezh Region, the mineralization of waters ensures a constant concentration of heavy metals and contributes to the accumulation of lead in fish.
