PARTICULAR QUALITIES OF MIGRATION AND CONCENTRATION OF MERCURY IN BOTTOM SEDIMENTS NEAR INDUSTRIAL TERRITORIES

Abstract: The article presents the results of a study of mercury and other heavy metals in the sediments of the Plyahovoy stream (territory of the former plant "Radikal", Kyiv), "Usoliekhimprom" and "Sayanskkhimplast" (Irkutsk region, Russia). Proceeding from the assumption that bottom sediments of water bodies are pollutant accumulators, the dynamics of pollution of the Plyahovy stream over 1997—2014, resulting in a positive dynamics of sediment purification from mercury (1997 — 100 mg/kg, 2002 — 7.6, 2014 — 5), although this data exceeds hundreds of times the background content. The processes of mercury absorption by sediments play an important role in the control of its migration and concentration, and are an important mechanism that influences the spread of contamination. Inorganic mercury compounds pass into elementorganic ones (methyl mercury) and are consumed by micro-organisms, which, in turn, are absorbed by fish. That is, the content of mercury in fish tissues can be judged from the intensity of sediments contamination. After analyzing the content of mercury in sediments (500—710 mg/kg), and fish (perch, bream, roach) of Bratsk reservoir, which belongs to the waters with technogenic pollution it has been found that the maximum accumulation of mercury in perch is 20.9 mg/kg (35 times higher than the maximum permissible content — MPC), roach — 13.6 (45 times higher than MPC) and carp — 1.91 (3 times higher than MPC). Perch and roach can be an indicator of sediment contamination by mercury.
Keywords: mercury, pollution, sediments, fish tissue.
