We studied mechanisms of geochemical soil systems formation. This work provides geochemical characteristics of soils under the influence of mining enterprises. It also shows the mechanisms of sewage water enrichment by heavy metals during sulphidic deposit exploitation and their interaction with soil substance. We also describe migrational activity of elements and the conditions of their concentration in the soil volume. It is shown that migrational activity of elements depends on both their chemical nature and the level of aggressive fractions of humus acids and background-forming elements (Fe and Mn) content. The level of heavy metal concentration in soils formed in the area of influence of deposits showed to be exceeded. We suggest new approach to complex evaluation of element reallocation mechanisms in soils.
Key words: Migrational activity of elements / Migration conditions / Element concentration mechanisms
