THE GEOCHEMISTRY OF HEAVY METALS IN THE ENVIRONMENT TECHNOGENIC CONTAMINATED TERRITORIES OF UKRAINE
Information from scientific report at the meeting of Presidium of NAS of Ukraine, June 17, 2015

Abstract:
Peculiarities of geochemical distribution of heavy metals in environmental objects that experience influence of industrial enterprises are studied. Technogenically caused associations of heavy metals in soils and bottom deposits are established on the base of geochemical criterions. Ecogeochemical mapping of the areas influenced by ferrous metallurgy and chemical enterprises is carried out on the basis of own experimental data. Areas of maximum level of poly-elemental soil pollution are revealed. Forms of finding and indexes of mobility of heavy metals in soils and bottom deposits are established. Biogeochemical indexes of technogenically polluted areas, i.e. coefficients of biological absorption of heavy metals, coefficients of biogeochemical activity of grassy and wooden vegetation, microbiological indexes of soils, are determined. Proposed new approaches to ecological-geochemical assessment of the zone influence of anthropogenic pollution.
Keywords: heavy metals, geochemical distribution, forms of finding, biogeochemical indexes.
