- Аннотация: For the first time in the city of Severobaikalsk, a soil-geochemical survey of the city territory was carried out in the summer of 2018 and the content of 16 heavy metals and metalloids (HMMs) in the soils were determined. 57 samples, including 10 background samples were taken from the upper soil horizon. The priority pollutants of urban soils are Sb Pb and W. The most contaminated soils are in the industrial, traffic and residential estate zones, and the least ones – in the residential multi-storey and recreational zones. In urban soils 4 associations of HMMs were identified: Cu-As-Mo; Sn-Sb; V-Cr-Co-Ni and Zn-Cd-Pb which come from common sources and having similar tendencies in accumulation and removal. Soil-geochemical maps were compiled on the territory of the city, where two anomalous zones with moderately dangerous pollution with Sb, As, Bi, Sn, Cu near the treatment facilities and a dangerous level of pollution with Sb, Sn, Pb, Cd, Cu, Mo at the locomotive depot were revealed. 63% of the city's territory has a moderate level of soil pollution with TMMs and 37% – dangerous and very dangerous levels.
