【摘要】 对南昌市城市发展区域400km²表层和深层土壤重金属含量情况进行了研究,初步查明该区存在较大面积的表层重金属集聚。Cu、Pb、Zn、As、Cd、Hg 单元素污染面积已达66．67%,全量分别为26．8±14．08 ms/ks、33．9± 15．60 mg/kg、79．5±38．20 ms/kg、9．1±3．34 mg/kg、160±205．67×10^-3mg/kg、104±150．66×10^-3mg/kg。以 Hg 和 Cd 元素污染为突出,具有分布面广和局部高强度等特征。老城区是重金属污染较为严重的地区,其中又以工业区为甚。随着城市规模的不断扩大,污染逐步延伸到新城区,并向规划区扩散。更多还原

【Abstract】 Having studied the situation of heavy metal contents in the topsoil and deepsoil with an area of 400km² in the developing area of Nanchang City proper,It is verified that there are large areas of heavy metal accumulation in the topsoil in the above-mentioned area.The area of single element contamination of Cu,Pb,Zn As,Cd and Hg is up to 66.67%;and total amounts are 26.8± 14.08mg/kg,33.9±15.60mg/kg,79.50±38.20mg/kg,9.1±3.34mg/kg,160±205.67×10^-3 mg/kg and 104±150×10^-3 mg/ kg respectively,in which,the contamination of Hg and Cd are outstanding examples with the features of wide distribution and high pol- lution degree locally.The old city proper is the major polluted area,especially in the industrial area.Along with the swelling of the cit- y,the heavy metal contamination will stretch into the new city area and even spread into the planned area.更多还原
