                    以萍乡地区具有典型代表性的城郊农村为例,对城郊农村土壤重金属的含量水平、分布特征进行研究分析。结果表明,萍乡地区城郊农村土壤中镉、汞、砷、铜、铅、铬、锌、镍、硒和钴的平均含量均未超过国家土壤环境质量二级标准,但汞、镍、钴的含量均超过了江西省土壤重金属相应元素的背景值,其中尤以汞最为显著。从研究区域的空间位置来看,居住区、农田区、蔬菜种植区的汞、镍、钴含量普遍偏高。
                
                Investigated the levels and reasons of ten types of heavy metals pollution(Cd, Hg, As,Cu, Pb, Cr, Zn, Ni, Se and Co) in the typical rural soils of Pingxiang city. The results showed that the average concentrations of Cd, Hg, As, Cu, Pb, Cr, Zn, Ni, Se and Co in the typical rural soils of Pingxiang were lower than the secondary background values of Jiangxi physical soil. From the spatial position of the study areas, the contents of Hg, Ni and Co in the residential district,farmland and vegetable plot were higher than other sampling points.
