APATITE MINING AND PROCESSING PRODUCTION AND EUTROPHICATION OF THE ARCTIC LAKE IMANDRA

As a result of the extraction and processing of the Khibiny apatitonefeline ores (Murmansk region), thousands of tons of mineral substances get into the aquatic environment, including the P and N compounds. Surface waters are the main migration medium of pollutants, most of which accumulate in the large eutrophied polar Lake Imandra. Annual receipts in the Bolshaya Imandra reach only along the Belaya River are estimated at 1,233 tons of N and 300 tons of P, which exceeds the critical load for the entire water body. The spatial and temporal dynamics of the main forms of P and N, features of the interrelationship of the Arctic lake pollution by macrobioge.
