The work is devoted to the problem of accumulation of heavy metals in the soils of industrial centers. The relevance of the work is justified by the need for regular monitoring and assessment of the state of the environment in connection with the deteriorating environmental situation in Yekaterinburg. The purpose of the work was to assess the contamination of the soil cover of the city of Yekaterinburg with heavy metals. The object of the study was soil samples taken in different districts of Yekaterinburg. The preparation of samples for analysis is described; The research methods are indicated: potentiometric (to determine the nature of the medium) and inversion-voltammetric (to determine heavy metals - lead, nickel, copper, zinc and cadmium). A map of the city with an indication of soil sampling sites is provided. It is noted that sod-podzolic soils predominate in Yekaterinburg, medium loamy in terms of granulometric composition. The sources of soil pollution are indicated, and the mechanism of accumulation of heavy metals in soils is given. The concentration coefficients of heavy metals and the values of the integral pollution index Zc are calculated; geochemical specializations of soils according to the concentration coefficients of heavy metals have been compiled. It was found that the soils of four sampling sites are characterized by a high level of pollution; the soils of eight sites are characterized by an average level. It has been established that technogenic geochemical associations of the composition Cd3-20 Pb3-18 Zn2-9 Ni1-9 Cu1-7 are formed in the soils of Yekaterinburg. It is emphasized that as a result of man-made impact, the level of metallization of soils in Yekaterinburg is quite high.
