Studying of Sn Concentration in the Soil Around Aluminum Factory in Arak City

In this study, in order to get more information about the condition of the pollution of soil all around Iralko, 11 samples were taken and from each region we have taken 2/3 samples and then complicated uith one another. To distinguish the amount of element (Sn) in the lab was tested. According to the results taken from the mean of concentration this element is 5 Mg/Lit. to find out the amount of pollution in the region which had al ready been studies from I poll as Geo chemical indicator. According to the amount of pollution, we put sn around the polluted area. Based on the results studied and comparison of concentration of this element with the mean of lager, it should be noted that soils around Iralk complex, are not too much polluted to this element, we canʹt present this region as polluted all around this hard element (with the element as pollution).
