Обсуждены основные факторы природно-техногенной среды, определяющие формирование экологических рисков в горнопромышленных районах южной части российского Дальнего Востока. In the present article discusses the main factors of natural and technogenic environment, determining the development of environmental risks in the mining areas South of the Russian Far East. The southern territories, with acid reaction of the medium and more active components that participate in natural supergene mineralogical-geochemical transformation of sulfide, feature formation of thick oxidation zones and formation of sulfates—most soluble mineral forms, as well as intensive chemical migration of pollutants in subsurface layers. Emerged from tailing storages, pollutants heavily contaminate aquatic ecosystems, surface water courses and ground waters, which allows ranking these territories the high-probability eco-risk zones. In the northern areas, lacking temperature equilibrium and characterized by all-round permafrost, mineral transformation processes are conserved inside the permafrost formations. Solubility of sulfides, as of most primary ore minerals, is millionth fractions, whereas solubility of sulfates is appreciably high; thus, transformation of the former group minerals to the latter group minerals dramatically aggrandizes the risk of toxic geochemical contamination of the environment.
