DYNAMICS OF MECHANICAL COMPOSITION, MOISTURE CAPACITY AND DENSITY OF TECHNOLOGICALLY CONTAMINATED SOIL

Abstract

The studies have established that the ratio of coarse and medium sand to the mechanical composition of the soil depends on the heavy metals content. A decrease in the ratio of coarse and medium sand shows a decrease in the toxic effect of technologically contaminated soil. As a result of the activities of CJSC “Yuzhpolimetall”, technologically contaminated biochemical regions have been formed, the heavy metals compositionin which exceeds the MPC several times.Surveys conducted on the territory of the production cooperative (PC) “Karnak”and the settlements of “Balaburgem” and“Kushata”showed that the priority soil contaminants in this region are such HMs as zinc and lead. It is known that their accumulation in the soil increases the toxic potential and sharply reduces soil fertility. The urgency of this problem is due to the soil heterogeneity in our region.
