Ivshina S. V., Papyan E. E., Safiullina L. M. CONTENT OF CHEMICAL SUBSTANCES IN SOILS AND DUST OF TECHNOGENICALLY DISTURBED TERRITORIES OF MINING ENTERPRISES IN SIBAI (RESPUBLIC OF BASHKORTOSTAN) // Научно-методический электронный журнал «Концепт». – 2026. – . – URL: http://e-koncept.ru/2026/0.htm

The results of chemical analysis of soils and soil dust for the content of Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Cd, Sb, Ba, and Pb near the tailings pond of the Sibai processing plant, located on the outskirts of the city of Sibai, are presented. Significant exceedances of the estimated permissible concentrations of metals were identified. The content of Zn and Cu in the soils exceeds the regulatory values by 6 to 9 times, Cd by 2.6 times, and Pb by 4 times, respectively. The amount of Cu in the soil dust is 9 times higher than the established level, Zn – 14 times, Cd – 4 times and Pb – 12 times, respectively. When comparing the content of heavy metals in soils and dust, a higher amount of them was found in the dust. The content of Cr in dust is higher than in soil (by 2 times), there are no sharp differences in V and Sc. High concentrations of MnO and Fe2O3 are observed in the soil dust. The content of most chemical elements in dust samples contributes to the rapid spread of pollutants into the natural environment.
