Abstract
The accumulation processes of chemical elements as well as distribution between abiotic (water, bottom sediments) and biotic (seston, zooplankton, fish) components of the Lake Bolshoy Vud’yavr ecosystem polluted by apatite-nepheline mining sewage for a long period, are analyzed. The values of the biological accumulation of the elements and their enrichment of water and bottom sediments are determined. The biogenic and terrigenous contribution of the chemical elements to the composition of bottom sediments has been estimated.
