Аннотация:The existing approaches to studying the risk of chemical contamination of soils are analyzed. It is
noted that the actual and critical loads of contaminants on the soil cover are often compared for estimating
these risks. The insufficient use of economic tools and methods for assessing the risk of soil contamination is
emphasized. The sanitary-hygienic standards are found out to be exceeded for lead, zinc, cadmium and copper
content in soils in six localities, each of 6250 m2 in the area, situated in the industrial and transport zones
of Podol’sk and Moscow. The values of actual and maximal permissible damage exerted by the heavy-metal
contamination to the studied soils are calculated. The probable damage R and the degree of probable damage
implementation (DPDI) are used as the indices of soil contamination risk.
