There have been examined the methods for estimating the degree of heavy metal contamination in soils. There have been revealed some discrepancies that concern estimation of soil contamination degree and calculation of consolidated figures for chemical elements contamination in soils stated in effective normative documents. The formulas for estimation of summary soil contamination stated in normative documents reveals considerable discrepancies that do not let give an objective estimation of dangerous concentration of heavy metal. We offer estimation of concentration of several chemical elements not by summarizing their concentration but by estimating their excess in relation to rock or its concentration in soil taken as a background
