摘要
对长沙市土壤重金属Cu、Pb、Zn、Cd、Cr、Hg、As污染现状进行了调查与评价。结果表明,长沙市110个样本中总体Cd、Cr污染程度已经属于重污染,Zn、As属于中污染,Cu、Pb、Hg属于轻度污染;不同母岩类型土壤中泥盆纪砂页岩、新生代沉积物、花岗岩的重金属含量较高。
The investigation and assessment of concentrations of heavy metal(Cu,Pb,Zn,Cd,Cr,Hg,As) in Changsha city were carried out.The result shows that the contamination level of Cd and Cr are subjected to heavy pollution in all 110 samples of Changsha city.The contamination level of Zn,As belongs to medium pollution and Cu,Pb,Hg belongs to slight pollution.The level of heavy metal of Devonian period sandshale,Cenozoic era sediment and granite are more than others.
