Abstract
Pollution of brown forest soils of Western Caucasus by heavy metals, oil and oil products in most cases causes deterioration of their biological properties. Based on toxicity degree heavy metals form the following sequence: Cr > Ni > Cu > Pb. Oil and oil products settle down as follows: oil > fuel oil > gasoline > diesel fuel. Quantitative reference points for development of regional standards of the maximum permissible contents in brown forest soils of chrome, nickel, copper, plumb, oil, fuel oil, gasoline and diesel fuel were proposed.
