FEATURES OF DEPOSITION OF HEAVY METALS IN THE SOIL COVER OF TERRITORIES OF INFLUENCE OF THE ENTERPRISES OF POWER SYSTEM OF DIFFERENT POWER
In work the assessment of influence of the enterprises of power system of various power (The Minusinsk and Abakan combined heat and power plant) on pollution of soils is carried out by heavy metals and features of their distribution in a soil cover of adjacent territories are revealed. By results of a research it is revealed that average concentration of heavy metals (Pb, Cd, Zn, Hg) in the region don’t exceed standards of the threshold limit values (TLV). At the same time, the average content of ions of copper in soils of all explored territories approaches standard value. Buffer properties of soils near the studied enterprises in different degree compensate technogenic loading of these sources of pollution. The soils around the Minusinsk combined heat and power plant characterized as low-buffer are more subject to pollution by heavy metals. The highest level of pollution of a soil cover is revealed by heavy metals in the northeast direction from borders of the studied enterprises that is caused by a complex of an environment which defines intensive distribution of aero technogenic emissions in this direction in comparison with southwest.
