Investigation of Soil Pollution from Heavy Metals and Assessment of Its Ecological Risk around a Smelting Plant in Shaoguan
摘要
Abstract
Objective] The characteristics and distribution of soil pollution from heavy metals around a smelting plant in Shaoguan were studied, and its ecological risk was assessed to provide theoretical references for the control and ecological restoration of soil pollution from heavy metals in the region.[ Method] Soil samples were collected and analyzed from the smelting plant area ,and the characteristics of soil pollution from heavy metals and potential ecological risk were studied by using the methods of Nemerow contamination index and geo -accumulation index.[ Result] Average contents of Pb,Cr,Cd and As in the soil were higher than the background values of soil in Guangdong Province and China ,and the con-tents of Cd and As exceeded the secondary standard of soil environment in China.Cd pollution was heavy,and Pb and As pollution were moderate, but the pollution was heavy in some areas;Cr pollution was mild.[Conclusion] Soil around the smelting plant has been polluted by heavy metals at different levels,and its potential ecological risk is moderate at least.关键词
