The influence of dust–gas emissions of aluminum manufacturing on soil cover of steppes in Minusinsk depression has been examined. Studied the geochemical behavior of fluoride in the profile saline soils located at different distances from the Sayank industrial cluster and varying degrees of anthropogenic impact. Intrasoil differentiation of water-soluble fluorine, which strongly correlated with nature of soil-forming processes, was investigated. The study of the salt composition of soil solutions, since the degree of salinity and chemistry determine the migration patterns of man-made fluoride. Saline composition of soil solutions was studied. This study aimed to identify directions and regularities of migration of man-triggered fluorine, which increases in saline horizons.
