| Abstract: | The concentration and the chemical speciation of Cu,Ni and Zn,as heavy metals' representives,were analyzed for the surface soil samples taken from the three parks inside the Wall of Xi'an City,and the heavy metal pollution level was evaluated by single pollution index and Nemero pollution index.The result showed that the soil appeared alkaline and contained plenty of organic matter,and the average concentrations of Cu,Ni and Zn were 36.96 mg/kg,24.32 mg/kg and 106.50 mg/kg respectively.The chemical speciati... |
