Abstract

The distribution of manganese and zinc in virgin and arable chernozems located near technogenic objects of the mining enterprise was analyzed. Soil sampling was carried out from soil sections. The analysis of soil elemental composition was carried out by x-ray fluorescence method. Mathematical processing of the results included the use of standard software packages for statistical calculations. It was ascertained that Zn belongs to the elements of concentration and Mn ? to the elements of the dispersion. Exceedings in relation to the maximum permissible or approximate permissible concentrations were not detected, but the concentration of manganese was above the background. The coefficients of radial differentiation in the upper horizons of soils for zinc are higher than for manganese and they are higher on virgin land than on arable. Concentrations of the studied elements in the upper layers of soils are weakly connected with the impact of dumps and tailings. The acid-basic property of soils is the significant factor influencing the distribution of the studied elements. Humus content and the amount of silt in soils have the weak influence.
