RAIL TRANSPORT AS A SOURCE OF SOIL CONTAMINATION WITH HEAVY METALS

This article discusses the pollution of soils with heavy metals in the vicinity of railways. Describes the ways and means of receipt of pollutants in soil. Investigated pollution with heavy metals of tap railroad Kuibyshev railway. Presents the results of the comparison of soil pollution with heavy metals in comparison with the maximum permissible concentration and regional background levels. The studied area of the Kuibyshev railway station 1004 km to the station Obsharovka direction Samara-Syzran on the contents in the soils of tap railroad 4 heavy metals: Fe, Сu, Мn, Cг. Revealed that the pattern of distribution of heavy metals away from the railroad tracks play a role as natural and artificial barriers. The natural barriers include shelterbelts, and the artificial - the presence of solid fences. Due to the close proximity of agricultural lands to railroad tracks is particularly important to take into account the contamination of soils by heavy metals in the bends of the Railways. Many heavy metals can accumulate in plants (agricultural) and, accordingly, to be involved in the system «plant - man; plant - animal - man», which contributes to the deteriorating health of the population.
