Abstract
The Kushk Pb-Zn mine is located in Central Iran and it has been in operation for the last 75years. To investigate the role of wind dispersion of heavy metal pollutants from the mine area, dust samples were collected during 1year and topsoil samples were collected around the mine. Results showed that the topsoil is polluted with Pb and Zn to about 1500m away from the mine. It was also found that there was not a significant difference between the metal concentrations in topsoil and dust samples. The Pb and Zn concentrations in the dust samples exceeded 200mgkg-1 and their lateral dispersion via wind was estimated to be about 4km away from the mine. It has been shown that a combination of mining activities and mechanical dispersion via water and wind have caused lateral movement of heavy metals in this area.
