Distribution of Chemical Elements between the Components of the Ecosystem of Arctic Lake Bolshoy Vudyavr (Khibiny, Murmansk Oblast)

Resumo

The processes of accumulation of chemical elements and their distribution between abiotic (water and bottom sediments) and biotic (seston, zooplankton, and fish) components of the ecosystem of Lake Bolshoy Vudyavr, which has been contaminated by waste waters of the apatite-nepheline mining complex for a long time, are considered. The values of the biological accumulation of chemical elements and their enrichment of seston, zooplankton, fish, and bottom sediments are determined. The biogenic and terrigenous contribution of the chemical elements to the contribution of bottom sediments is estimated.
