Natural process of soils formation happened throughout several millennia, and only centuries were necessary for their transformation to urban soils. The enterprises of power sys- tem daily release a large amount of various substances into the atmosphere, at the same time heavy metals fall into priori- ty pollutants: they are rather easily identified, sedentary in high soil layer. The fact is that the soil is geochemical barrier constraining transfer of chemical elements and their connec- tions on the profile and in underground waters, performing thereby important ecological function. The work purpose was the establishment of specifics of space deposition of some heavy metals (Pb, Zn) in soil cover of the territories adjacent to the enterprises of power system. Soil samples were select- ed in the points adjacent to Abakan and Minusinsk combined heat and power plant on the transects put, according to the priority directions of winds, in the northeast and southwest directions, apart 0.1; 0.5; 0.7; 1.0; and 2.0 km from the bor- ders of the enterprises, at the depth from 0 to 20 cm. The maintenance of ions of lead and zinc was determined by the method of inversion voltammetry. As a result of the research it was established that the level of pollution of soil cover with heavy metals differed both among studied enterprises and transects. The highest concentrations of heavy metals were revealed in the northeast direction from the borders of above-stated combined heat and power plants which had probably been caused by the complex of the environment which de- fined intensive distribution of aerotechnogenic emissions. Ion concentration of lead and zinc in the soils located in the northeast direction from the border of Abakan combined heat and power plant was higher than their contents in the soils of the same direction adjacent to Minusinsk combined heat and power plant, but were in the limits of the standard of maxi- mum allowable concentration.
