ГЕОХИМИЧЕСКАЯ ТРАНСФОРМАЦИЯ ЛАНДШАФТОВ ЖЕЛЕЗНОГОРСКОГО ПРОМЫШЛЕННОГО АРЕАЛА (КУРСКАЯ ОБЛАСТЬ)

The integrated geochemical researches of the natural-technogenic landscapes have conducted in the area of development of iron ore (Kursk oblast). The levels of soil, surface waters and bottom deposits of rivers pollution by heavy metals in the zones of influence of industrial facilities of Mikhailovsky mining and processing plant (MPP), including the territory of the city of Zheleznogorsk, have revealed. Soils of trans-accumulative landscapes, bottom deposits and waters of aquatic landscapes of the Pesochnaya, Chern, Rechitsa rivers have undergone the greatest technogenic changes. The content of Co, Ni, Pb, Zn in the soils is minimal, the content of Cu, Mn and Cr in some cases is equal to weak and medium levels of pollution. Tailings pond, quarry, dumps and municipal waste water lead to higher concentrations of heavy metals (Zn, Cu, Cr, Pb) in waters and bottom deposits of rivers. In aquatic landscape of rivers, there is a high content of soluble forms of Fe, which exceeds of maximum permissible concentrations for fishery objects in dozens of times, that is partly a geochemical feature of landscape complexes and surface watercourses of Zheleznogorsk industrial area.
