Contamination Assessment of Lead, Zinc, Copper, Cadmium, Arsenic and Antimony in Ahangaran Mine Soils, Malayer, West of Iran

摘要: Heavy metal contamination has become an important environmental hazard in recent years. In this study a soil-based geochemical survey the mining district of Ahangaran Malayer (Hamedan province, west Iran) was carried out. The concentrations Pb, Zn, Cu, Cd, As, and Sb were determined 40 topsoil samples. A number calculation methods have been put forward for quantifying level heavy metals on basis geoaccumulation index (Igeo), enrichment factor (EF), pollution (PI). calculated results Igeo EF reveal order is Pb > Cd As Cu Zn As. high Sb, soils indicate that there considerable pollution, which mainly originates from activities. are low assessment not significant. Assessment PI seriously polluted.
