| 摘 要： | 通过对新乡市区6个有代表性公园土壤重金属含量的调查,结果发现市区公园表层土壤Pb、Cr、Cd和Zn的平均含量分别为63.22 mg/kg、91.35 mg/kg、0.57 mg/kg、115.63 mg/kg。以河南省土壤背景值为标准,用内梅罗指数法综合评价,结果表明:6个公园土壤中重金属Cr、Zn为轻度污染;Pb为中度污染;Cd为重度污染。所有公园土壤都存在Pb、Cd和Zn污染。

| Abstract: | Heavy metal concentrations of surface soils taken from 6 parks in Xinxiang urban were studied.The results showed that the average concentrations of Pb,Cr,Cd and Zn were 63.22 mg/kg,91.35 mg/kg,0.57 mg/kg and 115.63 mg/kg,respectively.Based on the background of Henan soils,the park soils were lightly polluted by Cr,Zn;medium-polluted by Pb;and polluted seriously by Cd on Nemerow N L polluted indexes.All parks were polluted by Pb,Cd and Zn. |
