Together with the negative manmade impact and rapid growth of mining and processing industry the problem of environmental pollution with heavy metals becomes more and more urgent because essential land areas are represented by low-yield and less fertile soils.The subject of our research is the industrial area of Kvemo Kartli (Bolnisi-Kazreti) region, where, for the purpose of studying the impact on the environment of the available there deposits (“Madneuli” and “RMG Gold”) arable land have been analyzed for their content of the general organic matter, humus, soluble or movable forms of heavy metals, valence, toxicity level and its spread. The principal scientific and practical goal of our research is to study the toxicity level of contamination of arable lands with heavy metals by using modern test methods, to establish the soil reclamation and crop capacity.The modern EPA test methods have been used in the research, which represent a novelty and are unexampled for Georgia.To achieve one of the major goals of the subject, implying comprehensive analysis and results of the test subjects, the quantitative difference of the soluble, movable forms of heavy metals was determined by using the irrigation system of the River Mashavera before and after irrigation of arable land.To improve the research, the modern equipment, such as atomic absorption, spectral, infrared, ultra-red mass spectrometers, was applied.
