Ecological state of the territory of the Shtykovskaya technogenic and industrial system

摘要

The ecological state of soils as a component of technogenic and industrial systems has been characterized in the impact zone of mine terricones of empty coal-mining rocks. The results of analytical works showed the regional features of lithostrats and soils: the increased total content of hexavalent chromium (700 maximum permissible concentration (MPC) or more) and trivalent iron (18000 mg/kg or more). This is due to the relationship between the geochemical background of the area and natural technogenic factors under the conditions of monsoon climate promoting acidogenesis development.
