Abstract:

The results of studies of technogenic atmospheric pollution with disperse minerals in solid aerosol particles are presented. Mineral composition of solid aerosol particles in the air over Southern Baikal region is identified for the first time. Urban air is shown to be polluted with disperse emissions of quartz, calcite, feldspar, and amphibole. According to the data of snow-geochemical survey, mullite (Al₉Si₃O₁₉F) containing 28-32% of Al₂O₃ prevails in solid aerosol particles in winter. It is also the main component of power-production slag that allows its use as a secondary raw material for aluminum production.
