Changes in concentrations of nickel and copper in the surface layers of sediments of the Lake Imandra the last half century
Abstract. The analysis of the content of the polluting heavy metals Ni and Cu, priority for the region, in surface layers of sediments of the Lake Imandra, the largest reservoir of Murmansk region, has been carried out. The constant increase in the contents of Ni and Cu on all water area of the lake during researches has been determined owing to as direct intake of sewage of the enterprises of mining and metallurgical complex (Bolshaya and Yokostrovskaya Imandra), and aerial pollution of lake watershed and wind-induced currents (Babinskaya Imandra). The largest increase in the contents is noted in the Monche Bay of the Big Imandra up to 3 and 0.6 % for Ni and Cu respectively in the last years
