| Abstract: | Objective] Risk assessment of soil heavy metal on Qinghai plateau Huangshui basin was carried out.Method] The potential ecological harm coefficient method was adopted to assess the risk of soil heavy metal.Result] Cd,Hg,As,Pb,Cr,Cu in most regions belonged to developing ecological harm,and Cd,Hg a few areas belonged to medium ecological harm.Conciusion] There is a potential ecological harm of soil heavy metal on small part of Qinghai plateau Huangshui basin.The heavy metal elements which have the potential impacts on the soil are mainly Hg,Cd. |
