Ecological and functional estimation of soil condition within the zone of technogenic impact of Norilsk industrial complex

摘要

An analysis of the ecological and functional state of soils within the zone of air pollution of Norilsk industrial plants has been made. The criteria used for estimation are the content of heavy metals (HMs) and sulfur, as well as the microbiological activity of the soil. The basic polluting elements are distinguished. It is determined that the areas of extreme concentration of HMs in soils near the sources of emission are located along the directions of the prevailing winds. Structural and functional abnormalities in the microbial complex of the soil are marked out in the case of a strong disturbance of vegetation.
