​The present study reports on the geochemical composition of soils and bacterial and fungal isolates determined in the soils surrounding the Komsomolsk tailings, Kuznetski Alatau, Russia. The areas with high concentration of As, Sb, Cd, Pb, and Zn were revealed. The assessment of metal and metalloid contaminants was conducted on the soils using Pollution index (PI), Enrichment Factor (EF), and Geo-accumulation Index (Igeo). The indexes indicated serious Pb, Cu, Zn, Cd, Co, As pollution especially for soils sampled in the north-east direction. Using statistical methods, correlations between the geochemical composition of soils and microbiological community were obtained. The northern part of Komsomolsk tailings is characterized with the maximum amount of bacterial strain in soil samples. Among gram-positive microbes, there is a domination of Bacillus, with the absence of Microbacteiaceae and suppression of Micrococcaceae.
