Abstract
Toxic element distribution in ash-and-slag wastes from the fuel-and-energy complex of the enterprises of Kemerovo Region was studied. The mobile species of copper, nickel, zinc, lead are revealed to migrate into the groundwater. It is demonstrated that the ash-and-slag wastes in the case of contacting with water become a source of toxic elements (vanadium, molybdenum, arsenic, nickel, zinc, manganese and chromium). The content of these elements in groundwater in the territory of ash-and-slag dumps and adjacent natural water sources significantly exceeds the maximum permissible concentration thereof in water.
