Khabirov I.K., Asylbaev I.G., Lukmanov N.A. RETROSPECTIVE MONITORING OF ZINC, ARSENIC, LEAD AND CADMIUM IN SOILS OF FOREST AND MEADOW ECOSYSTEMS SOUTH URALDue to living matter in the soil are concentrated and redistributed post-drank from the rock, the atmosphere and living organisms, chemical elements throughout the periodical systems, which are destroyed in their turn to form new compounds, they are under the constant influence of kinetic and thermodynamic forces animate and inanimate nature. The article presents the materials on the content of zinc, arsenic, lead and cadmium in the soils of the Southern Urals. The behavior of these elements in the retrospective aspect. SimilarResearch in the Southern Urals has not yet been carried out. The first results shows the presence of significant changes in the content of elements in the retrospective aspect. New concepts like biogeochemical activity and biogeochemical potential element in the soil. The thermodynamic performance oxides Education: Enthalpy, Entropy, Gibbs Energy. It was found that the greatest contribution to the soil-forming process in the conditions of Southern Urals are making zinc, arsenic, to a lesser extent lead and cadmium, to a small extent. From the point of view of ecology are major pollutants zinc and arsenic. Hundred- arable soil on the content of zinc, arsenic, lead and cadmium degraded almost to the level of a light-gray forest soils, evidenced by stocks of these items on a profile soil and thermodynamic constants.Key words: a retrospective analysis, the Southern Urals, thermodynamics, zinc, arsenic, lead, cadmium.
