Abstarct: Mining and its related activities are the most important source of mextals in soils. The main aim of the present study is to investigate the accumulationand the pollution level of heavy mextals in soil around Duna Pb-Zn mine and its tailing dam. To do so, 12 soil samples were collected from the mine site and around the tailing Dam. Several physicochemical parameters (Organic matter, Ph) of soil and the concentration of heavy mextals (Pb,Zn,Cd,Cr,Ni and Cu) were measured by standard methods. In addtion, some soil samples were analysed by four stage sequential extraction analysis (BCR) to determine the domainat geochemical forms. The result shows that the average amount of pH and organic matter are 7.60 and 2.11 which shows the uneven distribution in soils. According to geochemical data the concentrion of most mextals specially Pb, Zn and Cd with a mean of 8170, 1217 and 9 mg/kg in the soils around mine site which are significantly higher than the global soils and local unpolluted soils. This is confirmed by (geoaccumulation ) and pollution factors. According to the results of sequential analysis more than %50 of Pb and Zn in the second phase and more than %60 of Ni, Cr and Cu is accosited with the residaul phase. According to this results, Zn and Cu have that most mobility factor among mextals. The calculated correlation coefficient show the positive correlation between mextals and also between mextals and some physicochemical parameters of soil such as the amount of organic material which show the comman source of these mextals related to mining activities in this site.
