西安市革命公园土壤重金属含量及污染评价
Concentration determination and contamination evaluation for heavy metals in the soil of Geming park in Xi'an
摘要
Abstract
Heavy metal concentration and chemical speciation of Cu, Ni, Zn, Cr, Cd and Zn were analyzed for the surface soil samples taken from the Geming park in Xi'an, and the heavy metal pollution level was evaluated by single pollution index and Nemero pollution index. The result shows that the soil appears alkaline and contains plenty of organic matter, and the average concentrations of Cu, Ni, Zn, Cr, Cd and Pb are 27. 30mg/kg, 26. Olmg/kg, 90.29mg/kg, 71.06 mg/kg, 0.184 mg/kg and 51.61 mg/kg respectively. The chemical speciation of Cu, Ni, Zn, Cr and Cd mainly exist in residual forms except Pb. The average Nemero index is 2.70, that is the soil has been moderately polluted by heavy metals. And the Soil contaminated by Pb is the most severe.关键词
