Abstract

The article contains information about the study of soils of residential areas of the city of Ussuriysk, PrimorskyKrai, on the content of heavy metals: lead, cadmium, zinc and nickel. In 90 soil samples taken in different parts of the city, anthropogenic load and development pressure, modern levels of heavy metals in different soil types have been identified. The regions experiencing the greatest load are allocated. The highest concentrations of lead are observed in the soils of the central and western parts of the city. There is a tendency of decrease of the content of gross forms of lead in soils of the city district in the last decade. On the content of cadmium, Ussuriisk is referred to non-polluted areas, whereas the content of zinc and nickel can be considered high, all the studied soil samples had a concentration of Zn exceeding the MPC and more than half of the samples exceeded the Ni content. These elements can be considered the priority pollutants of the city environment.

Keywords
