摘要：

Pollution of aquatic ecosystems by heavy metals is one of the global problems of modernity. For the first time for the conditions of the this region carried out comprehensive studies on the study of content migration - Fe, Ni, Hg, As, Cd, Cu, Pb, Zn in aquatic habitats that defines the novelty of research. Total index of water contamination with heavy metals create the decreasing row Fe> Zn> Cu> As> Ni> Pb> Cd, and in bottom sediments TM compounds decreases in the row Fe> Zn> Ni> Cu> Pb> As> Cd> Hg. Have been established that, the major pollutants in water of the Caspian Sea were zinc and copper. Their concentrations are constantly exceed the MPC of fish farm (zinc-0,01-0,05 mg/l, copper-0,001 mg/l), whereas in bottom sediments the excess of MPC was not observed.
