The total content and content of mobile forms of potential soil pollutants (Cd, Pb, Zn, Cu, Sr, F, S) are determined in the topsoil in the impact zone of a cement plant and phosphorus fertilizer factory. The total concentration of Cd (4.0 mg/kg), Pb (99.4 mg/kg), F (15.2 mg/kg), and S (479.6 mg/kg) is found to exceed the established maximum permissible concentrations (MPC, APC). The local concentration maximum of the major pollutants is observed at a distance of 0.5 and 1.0 km away from a phosphogypsum stack. Comparing sampling plots equidistant from the pollution source reveals that alluvial soils have accumulated 1.5–2 times more total forms of Cd, Pb, Zn, Cu, S than agrosod podzolic soils.
