Geochemical peculiarities of soils in Tomsk areas of industrial enterprises locations

The study of soil samples taken in regions of the industrial enterprises locations in Tomsk areas was performed. The instrumental neutron-activation analysis was used for determination of the chemical composition of samples. The accumulation levels of 26 chemical elements in soils, including rare and radioactive, were determined. The level values of all of the studied elements exceeded background concentrations. The observed elements concentrations exceeded the background ones by factor ranging from 1.1 for Rb (Artificial stone plant) up to 20 for Br (Borrow pit enterprise) to 28 for Ce (Ash dump of the heat power station). The pollution of all studied areas was estimated as high on the basis of calculated values of the total pollution index. The soil geochemical peculiarities in Tomsk are established by elements accompanying production in regions of industrial enterprises locations. The soil composition reflects the specificity of the urban area with various industrial enterprises, due to certain properties of the soil, which constantly accumulates pollutants of emissions from businesses shops and vehicles.
