Abstract
Regional maximum permissible concentrations of gross lead in soils were determined in the area of the non-ferrous metallurgy enterprise – the largest Electrozink plant in Russia, located in Vladikavkaz (Republic of North Ossetia-Alania) and a source of environmental pollution with lead, zinc and cadmium. Modeling of lead contamination of five types and subtypes of soils most closely lying to the metallurgical enterprise was carried out. The following of gross lead concentrations were established in soils in the area of the metallurgical enterprise: chernozem leached – 160 mg/kg, chernozem ordinary – 150 mg/kg, dark gray forest – 120 mg/kg, mountain-meadow soddy – 110 mg/kg, brown forest weakly unsaturated – 100 mg/kg.
