Marine Ecological JournalРезюме: | It is determined, that the critical zones on 90Sr, 137Cs, 239,240Pu, 210Ро, Hg, and chlororganic pollutions in the Black Sea are situated in water areas, adjacent to the territories with developed technogenic activities and in the regions of intensive use of natural resources. Flows of the pollutants deposition into geological depot in critical areas is much higher than in the conditionally clean areas. It is caused to the influence, which is implemented in accordance with the principle of Le Chatelier-Braun, of biogeochemical mechanisms of interactions of living and abiotic substances with the radioactive and chemical pollutants in the marine environment, as well as by the factors of formation of the sedimentation processes as a result of the biological productivity waters and the rates of the reproduction of allochthonous and autochtonous mineral and organic suspensions. Maximum intensity of biogeochemical processes of conditioning is equal its ecological capacity at achievement of the the limits of sorption and metabolic saturation by pollutants of the living and abiotic substances of the marine environment. |
