Abstract
The distribution of total forms of heavy metals Cu, Cd, Ni, Pb, Zn, Co, Hg, and As in technogenic soils has been evaluated using geochemical research methods. Diagnostic indicators of damage of soil natural properties in the area of technogenesis are revealed. Statistically significant empirical dependences toxic elements migration on the buffer properties of soils (pH, N, Corg) and salinity factor of the territory are obtained. It is shown that in the zone of industrial objects in the soil surface layer, lateral technogenic geochemical pollution modules can be formed at depth down to 30-50 cm. This should be taken into account when evaluating the environmentalrisk of a territory and in the environmental control of soil pollution.
