Abstract
Natural and technogenic sources of mercury ingress to into ecosystems of Gorny Altai were characterised. The content of mobile Hg forms in polluted soils was determined and its inverse dependence on the gross content of mercury in the soil was revealed. The limited nature of migration of mobile forms of mercury from polluted soils was demonstrated. The main thermoforms of mercury in conditionally background and anthropogenically polluted soils were preliminarily found. Data on levels and forms of its occurrence in components of water ecosystems are presented. Features of their changes in different hydrological periods, and also during the water transfer are revealed. Quantitative characteristics of transfer of various forms of mercury coming from the industrial zone of the Aktash mining and metallurgical enterprise were assessed. A progressive decrease of their content in the waters that transmit pollution of rivers of the fifth-second orders (Yarlyamry, Chibitka, Chuya, and Katun) was shown.
