Abstract: In Georgia, as well as in the South Caucasus region as a whole, it is an urgent necessity to conduct environmental and eco-expert studies according to threats and challengesusing respective utilizing and neutralizing systems. Agricultural soils of the Kakheti region were studied, which implies the classification of soil structure, mechanical division of organic matter by its percentage content, investigation of the cation exchange capacity (CEC), mobile, soluble forms of heavy metals and nutrients. A liquid stimulator was used, which ensured the binding-accumulation process of excessive heavy metals in the soil up to the maximum allowable contamination (MAC). The soils of the Kakheti region were found to be moderately and heavily clayey, and black soil types with the medium and high fertility growth rate. Their excessive content of calcium, iron, sodium, nitrogen and phosphorus can be supposedly explained by the overuse of chemical fertilizers. It is established that mobile-soluble forms of heavy metals (lead, copper, zinc) in the soil exceed MAC. Research work was carried out using such physic-chemical research methods as atomic-absorption, X-ray fluorescence, the EPA TCLP and WET test standards, and quantitative-chemical analysis.
Key words: ecotoxicology, heavy metals, TLV, research methods, remediation, pesticide, leaching.
