ABSTRACT
Global environment pollution and environmental safety has become problem no. 1 of the XXI century, and its outcomes in Georgia are evident, as on the background of growing anthropogenic impact, protecting the single and whole complex of the environment, as well as its individual components is an extremely urgent issue. Agriculture is an old branch in our country, and maintaining the productivity of agricultural plots and soil resources in general, in terms of impact of modern natural and technogenic factors can be deemed a strategic objective and resource for the country.
One of the sources of soil pollution is agriculture, with the means chemization it uses: mineral and organic fertilizers, pesticides, plant growing stimulants, etc. It should be noted that heavy metals have a particular impact with their stress-indexes.
Accurate quantitative evaluation of the impact of heavy metals on soil productivity is quite difficult. One of the most important regions studied by us to create a maximally real picture of agricultural conditions is Bolnisi municipality. Mostly meadow and forest transient brown soils characterized by average and high content of humus, favorable mechanics, neutral and alkaline-prone reaction are spread in the municipality. At the same time, Bolnisi municipality is an important mining region. The mining enterprises here have a strong technogenic impact on the environmental components: soils and waters, i.e. the soils are subject to a growing anthropogenic-technogenic impact.
The subject of our study is to give quantitative evaluation of the impact of the mining industry on soil and water pollution, in particular, the article analyzes the migration frequency and variability of heavy metals (lead, zinc, copper and cadmium), natural and technogenic factors causing pollution, types and areas of pollution and their impact on the adjacent agroecological systems, etc.
Following the large-scale evaluation of these issues, the risks of non-favorable hazardous situations will be possible to determine what on its hand will promote the harmonious co-existence of the man and the nature and will contribute to the improvement of the situation.

Keywords: heavy metals, soil and water pollution.
