Abstract
In 2021, concentrations and elemental chemical composition of the inorganic part of solid snow impurities were studied on the territory of the Norilsk Industrial District. Based on the analysis of these data, a list of priority polluting chemical elements is compiled (Ni, Cu, Cd, Co, Sn, Pb, B, and Zn) and a method for quantifying the contribution of atmospheric emissions from Nadezhda Metallurgical Plant to aerosol pollution of the territory is suggested. In the sub-latitudinal direction, emissions from this plant predominate in dust pollution of the air at a distance of up to 7 km from the source.
