Abstract. The article presents research to assess the contamination of heavy metals in the soils of the industrial site of the former battery plant «Vostsibelement», located in the municipal formation «city of Svirsk» of the Irkutsk region. Currently, the industrial site with an area of 33 hectares contains the ruins of workshops and construction waste, technogenic soil contaminated with heavy metals, as well as waste of unknown origin that pollutes the environment. In soil samples taken at the industrial site, an excess of approximately permissible concentrations of gross forms of metals was recorded for lead up to 862 times, for zinc up to 42 times, for copper up to 24 times, for nickel up to 2,8 times and for arsenic up to 52 times, and the maximum — permissible concentrations for mercury up to 3,2 times, for manganese up to 3 times. Based on the results of quantitative chemical analysis of soil samples, the authors calculated correlation coefficients using Spearman’s rank correlation coefficient. The greatest correlations were established between mercury and zinc (0,78), lead and manganese (0,76), copper and manganese (0,75), zinc and manganese (0,72), lead and zinc (0,71), zinc and copper (0,68) and lead and copper (0,65), while the obtained values indicate their high degree of close connection. Based on the results obtained of the redistribution of heavy metals in the studied soils and the presence of anomalous zones of contamination of the industrial site, the authors proposed two complementary technical solutions for its reclamation. The first technical solution is to regulate the mobility of heavy metals in moderately contaminated soils of an industrial site through the use of sorbent soil from frozen colloidal sludge-lignin sediment. The second technical solution is the reclamation of technogenic soils with abnormal content of heavy metals through the recovery of metal lead by air separation.
