Technogenic provinces

The metals sulfides are the most dangerous since after aerobic weathering they are transformed into water-soluble sulfates of different metals. Accordingly, in the areas of non-ferrous and rare metal ore exploration and treatments, the acid sulfate landscapes are formed with high content of toxic metals. The biogeochemical technogenic provinces are known, for instance, copper-nickel provinces in the Kola Peninsula, Fennoscandia molybdenum provinces in the Caucasian region, copper and chromium-nickel ones in the South Ural, poly-metal ones, in the Pacific coast of eastern Eurasia (Russia, China, and Korea), etc. 

HUMAN HEALTH ENDPOINTS IN TECHNOGENIC AND AGROGENIC BIOGEOCHEMICAL PROVINCES... 

Box 3. Statistical assessment of morbidity in technogenic and agrogenic biogeochemical provinces of North Eurasia (after Evstafyeva et al., 1999)... 

These peculiarities of urban area development led to the technogenic biogeochemical provinces, i.e., the areas with local increase of pollutants in different components of urban ecosystems such as soils, grounds, surface and ground waters, plants, atmosphere. These pollutants create ecological risk to human and ecosystem health by their accumulation in the biogeochemical food webs (food stuffs and water). 

The problems related to the biogeochemical mapping are complicated by the technogenic transformation of natural ecosystems and relevant primary biogeochemical provinces and their transition to secondary biogeochemical provinces. During...
