Abstarct: The purpose of this study was to evaluate the total and bioavailable concentraions of potential toxic elements in soil around the Anguran Pb-Zn mine. For this purpose, 18 topsoil (0-30 cm) samples were collected. The total concentrations of major and trace elements were measured using ICP-OES. The physico-chemical properties of the soil samples were determined using standard methods. In order to assess the bioavailability of potentially toxic elements, the soil samples were digested by single extraction method. baxsed on the results, the soil samples were sandy-loam and sandy-clay-loam. The average values of pH, organic matter, and carbonate contents in the soil samples were 7.8, 3.4%, 184.2 μs/cm and 22.08%, respectively. The highest concentration of Pb, Zn, Cd, As, Cr and Ni were recorded in the mining area. On the basis of enrichment factor and geoaccumulation index values, the soils of the mining district are highly polluted with Pb, Zn, Cd, As, Cr and Ni. The single extraction analysis indicated that Cd is the most bioavailable elements in the studied soils. High intensity of soil contamination and high biodegradability of Cadmium element indicate the necessity of environmental management of mining activities in the area of Anguran lead and zinc mines.
