This study is dedicated to the assessment of the heavy metal pollution of soil by determining the category of soil contamination due to the activities of mining and chemical enterprise. The X-Ray Diffraction method was used experimentally to determine the qualita-tive and quantitative composition of heavy metals and other inorganic elements in samples, soil pollution with heavy metals. Main sources of heavy metals in industrial waste are identified. The environmental pollution with some heavy metals (Sr, Cr, Pb, Zn, Cu, Mn) was assessed and exceeded the MPC. The ecological situation of soil contamination with heavy metals near tars on the study area territory is estimated in the category from permissible pollution to hazardous pollution. Soil near the phosphogypsum dump is classified as an acceptable, moderately dangerous, and dangerous category of soil pollution. It was established that at a distance of 20 m from the tailings the soils belong to the dangerous category of soil, closer to the tailings – to moderately dangerous. The value of the concentration coefficient indicates the activity of leaching processes (Cc < 1) and accumulation (Cc > 1) of substances in the genetic horizons of the soil. It is necessary to forecast the state of the environment in the area of influence of these enterprises to develop effective means of ensuring environmental safety.
