Features of the elemental chemical composition of the magnetic phase of the urbic soil of the industrial city

A relevant environmental problem in cities is the increased concentration of some heavy metals in soils. Heavy metals come to the soil from natural and anthropogenic sources. Emissions from industry, transport, and fertilizers are anthropogenic sources. In the soil, heavy metals are bound by carrier phases: organic matter, clay minerals, sulfur compounds, oxides and hydroxides of iron and manganese. Highly magnetic iron-bearing minerals are concentrators of heavy metals in soils. The aim of the study is to characterize the features of the elemental chemical composition of the Urbic soils and its magnetic phase of the industrial city Gubakha, Perm region (Russia). We used the background soils, the clarke of the lithosphere, and the clarke of the soils of the world to assess the ecological-geochemical role of the magnetic phase in the accumulation of heavy metals. The magnetic phase is rich in Fe, Ni, Cu, Cr, and Zn. The Urbic Technosol Loamic, Skeletic of the city Gubakha is contaminated with Cu, Cr, Ni, and Zn. Ecological-geochemical monitoring of the soil cover by the method of ecological magnetism is relevant in the territory of the cities.
