Ecological and Functional Estimation of Soil Condition within the Zone of Technogenic Impact of Norilsk Industrial Complex
The analysis of ecological and functional state of soils within the zone of technogenic impact of Norilsk industrial plants was made. The criteria used for evaluation were: the content of heavy metals and sulfur as well as microbiological activity of the soil. The basic polluting elements were distinguished. As it was determined, the areas of extreme concentration of heavy metals in soils near the sources of emission were located along the directions of the prevailing winds. Structural and functional abnormalities in the soil microbial complex were marked out in case of strong disturbance of vegetation.
