Features of the Distribution of Heavy Metals in the Soil of the Railway Yard

Abstract

The distribution of heavy metals in soils in the sorting station of Lublino-Sortirovochnoye Kursk direction of the Moscow railway in the southeastern district of Moscow with the help of sampling profiles is considered. Analysis of the distribution of metals in the northern, southern parks, the central line of the station and along the main course is given. The characteristic groups of metals that determine the nature and level of contamination of the station, as well as a number of predominant heavy metals are presented. Their distribution at three stations stopping at a distance from the main course is considered. The categories of soil contamination and the contribution of each metal are determined taking into account the halos of the dispersion of enterprises. A comparison of the soil of the sorting station with the level of contamination of the strip for the removal of segments of the railway lines of the Kursk and Kazan directions is given. Recommendations are given for reducing the content and distribution of heavy metals in urban areas.
