PATTERNS OF HEAVY METALS ACCUMULATION IN FISH IN LAKES OF THE FENNOSCANDIAN GREEN BELT (IN THE MURMANSK REGION)
The patterns of heavy metals (HM) accumulation in fish from lakes of the Murmansk Region within the Green Belt of Fennoscandia (GBF) exposed to long-term air-borne pol-lution associated with the operation of a non-ferrous metal processing enterprise have been studied. The detrimental effects of air-...

The patterns of heavy metals (HM) accumulation in fish from lakes of the Murmansk Region within the Green Belt of Fennoscandia (GBF) exposed to long-term air-borne pol-lution associated with the operation of a non-ferrous metal processing enterprise have been studied. The detrimental effects of air-borne water pollution from the Kola GMK mine and smelter do not depend on the dominant wind directions. The reduction in emis-sions from the Nickel site of the Kola GMK in the past decades has not led to a significant decrease in the level of anthropogenic load. On the contrary, a long-term upward trend is observed in the content of Cu in the organs of whitefish, char, pike and perch in all the lakes studied. The accumulation of Cu and Ni in fish target organs tended to decrease along the distance gradient from the source of pollution. The revealed pattern is con-sistent with the intensity of pathologies development in whitefish organs. The common whitefish (Coregonuslavaretus(L., 1758)) is the most reliable test object that reflects the degree of pressure from long-term exposure to HM.
