Identifying the distribution of a number of heavy metals near the industrial area, taking into account the wind rose in the region during the period of operation of the Hrazdan Thermal Power Station and the Hrazdan Cement Plant was investigated in a radius of one km. In a series of experiments, was found a decreased concentration of arsenic and mercury in soil samples by an average of 27% with distance from the industrial area. In that direction, in the soil sample, there is an increase in the concentration of zinc and nickel by an average of 25.5%, as well as an increase in the concentration of copper by 19%. At the same time along the sampling line, the comparative series generally has the following sequence: As<Ni<Co<Cu<Zn<Pb. In the quantitative assessment of soil, contamination was compared to geo-ecological coefficients: the danger level of soil contamination and the total pollution index. Their calculation was based on the values of heavy metals concentration according to Clark and their maximum allowable concentration. Our forthcoming studies will focus on identifying the dose-effect-rose-wind relationship in arable soils with varying degrees of metal contamination as a result of long-term anthropogenic pollution.
