The migration ability of heavy metals in soils as the sensitivity indicator of geosystems

L.N. Semenova and Yu.M. Semenov

Presented are the results from studying the behavior of the total and labile forms of iron, titanium, manganese, chromium, vanadium, nickel, cobalt, copper and lead in the soils of the geosystems of the Khamar-Daban Range; their relative contents have been calculated. The role of acid- and water-soluble forms of the elements in radial migration of the heavy metals is considered, and its magnitude is inferred by means of the sorption lysimeters. It is shown that the migration ability of heavy metals can serve as the sensitivity indicator of geosystems to external impacts.
