Abstract
The paper examines pollution of soils with heavy metals under technogenic impact. The ways and means of pollutants receipt in soils and their accumulation in soils located in the drainage of railway are described. The role of roadside forest belts on the distribution of pollutants is examined. Determination of heavy metals content in soils was carried out by the x-ray fluorescence method. The results of heavy metal soil pollution in comparison with Clarke value, maximum permissible concentration and regional background levels are represented. The study of heavy metals content was carried out in the soils of right-of-way on the Samara-Syzran section of the Kuibyshev railway, as well as in suburban forests and urban parks of Samara (Botanical garden, Country Park). These areas are exposed to significant anthropogenic impact. Studies have shown that in these areas an increased content of some heavy metals in soils is observed. The main elements present in anthropogenic flows of pollution are copper, nickel, chromium, zinc and lead. This result does not contradict the standard environmental situation. These materials can serve as a basis for further monitoring of suburban forests of Samara green zone and transport facilities
