Abstract

Soil pollution with Cr, Cu, Ni, and Pb oxides or crude oil has an adverse effect on biological properties of ordinary chernozem. The degrees of their deterioration in laboratory and field experiments do not differ statistically, indicating that the results of laboratory modeling may be correctly extrapolated to the field scale. Pollution of ordinary chernozem with oil affects biological properties of both topsoil and subsoil horizons, while Pb is harmful only for the upper soil horizon. Concentrations in excess of 25 mg/kg for Pb and 0.25% for oil in ordinary chernozem are not ecologically safe (not allowable).
