Evaluation of Pollution of Soils with Potentially Toxic Elements in the Zone of Influence of Potassium Salt Mining

Abstract

The results of the assessment of soil contamination with potentially toxic elements (Sr, Pb, As, Zn, Ni, Co, Mn, Cr, V, Ti, Fe) in the zone of influence of potassium salt mining at the Verkhnekamskoye deposit (Perm region) are presented. A comparison is made with the clark, the regional background of the Perm region and the background of the natural region of the Southern Taiga. Data on the accumulation and dispersion of elements under the influence of the extraction of potassium salts in the humus and podzolic soil horizons were obtained, and geochemical series were compiled.
