摘要
通过对徐州市泉山、云龙、鼓楼、九里4个城区的公园绿地土壤进行系统采样测定,对其土壤重金属富集与污染状况进行分析与评价。结果表明,该城区表层土壤中5种重金属(Cd、Cu、Zn、Pb、Cr)含量均高于中国土壤元素背景值,其中Cd单因子富集指数为30.00,污染指数为14.56,富集程度较高,污染较严重;Cu、Zn、Pb、Cr单因子富集指数和污染指数均接近1,富集程度较低,无污染或轻度污染。
The enrichment and pollution situation of heavy metals in Xuzhou urban greenbelt was analyzed and evatulated by sampling and mensurating the soil in Quanshan,Yunlong,Gulou and Jiuli Districts of Xuzhou.The results showed as follows:the content of 5 types of heavy metals(Cd,Cu,Zn,Pb,Cr)were all higher than Chinese background value of soil elements,among of these heavy metals,the enrichment of Cd was higher and polluted quite seriously;the enrichment of Cu,Zn,Pb and Cr was lower,and not polluted or polluted l...
