Concentration of heavy metals in the soil cover of industrial zones of Krasnoyarsk

Abstract

The article is devoted to the assessment of soil pollution in industrial zones of the city of Krasnoyarsk. The comparison of the regions of Krasnoyarsk CHPP-1, Krasnoyarsk CHPP-2 and Krasnoyarsk CHPP-3 is performed by the total index of soil pollution with heavy metals. The representativeness of the obtained data was confirmed by the corresponding statistical processing. In the studied areas, an increased content of mobile forms of lead, cadmium, copper, nickel, zinc, manganese, cobalt, chromium was recorded, which, in contrast to the control, is higher on average by 2.7; 2.6; 5.1; 6.1; 6.7; 4.4; 2.1; 1.7 times, respectively. An excess of the MPC (APC) for the elements under study was recorded, and only the content of mobile forms of cadmium in all 3 industrial zones does not exceed the MPC (APC). In the areas of TPP-1, TPP-2 and TPP-3 of the city of Krasnoyarsk, the content of Co, Cd, Ni and Mn has an indicator value. Indicators of the level of accumulation of heavy metals can be used in monitoring urban areas.
