Abstract
The paper shows under what loads of pollutants occurs their accumulation in soils with the course of time. A map of soil contamination with fluorine, reflecting the patterns of its secondary differentiation in steppe geosystems, is presented. The features of fluorine distribution in soils depending on the environmental conditions, as well as the factors that ensure self-cleaning of contaminated soils are revealed. The necessity to reduce dust and gas emissions during the production of aluminum is emphasized.
