In recent years, soil pollution of large industrial cities with heavy metals has become an important environmental problem. The city of Omsk is a large industrial center of Siberia. At the same time, comprehensive studies of the state of the soil cover of the city of Omsk for the content of heavy metals in the surface layer of soils of various functional zones (industrial, transport, nitrate, and recreational) were not carried out. The purpose of the study is to assess the environmental and geochemical state of soils of various functional zones of Omsk in the content of heavy metals. In the selected soil samples, the content of 5 heavy metals was studied: zinc, copper, lead, cadmium, and arsenic. The definition of Zn, Cu, Cd, and Pb was carried out by atomic-aborreational spectrometry with fiery atomization. As was determined by the photometric method. In the course of the studies, it was found that in the surface horizon of soils of Omsk, zinc and lead are priority pollutants. According to the total indicator of pollution, the soil cover of Omsk is characterized by a high level of pollution. In the transport zone, 57.1% of the soils have a dangerous and extremely dangerous level, 14.3% – moderately hazardous and 28.6% – permissible. In the industrial zone, a dangerous and extremely dangerous level of pollution was noted by 92.3% of the soil surveyed. Based on the IPS indicator, separate polluted areas requiring remediation were identified. They are mainly located in the impact zones of enterprises and near large transport motorways. In the residential and recreational zones of Omsk, a more or less favorable situation in the content of heavy metals is developing.
