Spatial variability of available Pb and Ni in soils around two smelters in central Iran

摘要：

Past investigations have shown that industrial and agricultural activities may result in accumulation of heavy metals in soils. A total of 208 soil samples were collected from a 300 km2area covering an industrial zone in western Isfahan, central Iran. Available Pb and Ni were measured in all the soil samples. The metal concentrations were mapped using kriging. The concentrations of Pb and Ni were higher in soils around two smelters than in other areas, indicating that these industrial activities resulted in soil contamination by heavy metals. Although the soil concentrations of Pb and Ni were still below threshold levels, caution should be taken to avoid further inputs of heavy metals to soil.
