Spatial distribution of heavy metals in soils as geoenvironmental problem of power system enterprises

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...
