摘要
以武汉市东湖高新区农田土壤为研究对象,共采集58个土壤样品,分析8种重金属(Pb、Cd、Cr、Hg、As、Ni、Cu、Zn)的含量,以土壤环境质量农用地土壤污染风险管控标准(试行)为评价基准值,采用单因子污染指数和内梅罗综合污染指数评价该地区土壤农田重金属污染状况。结果表明,东湖高新区农田土壤总体处于清洁水平,小范围(1.72%)存在Cd轻度污染,未发现农田土壤受到As、Pb、Ni、Cr、Cu、Hg、Pb的污染。
A total of 58 soil samples were collected from farmland soils in Wuhan East Lake High-Tech Development Zone.The con⁃tents of 8 heavy metals(Pb,Cd,Cr,Hg,As,Ni,Cu,Zn)were analyzed.The single factor pollution index and Nemerow syntheti⁃cal pollution index were used to evaluate the heavy metals in farmland soils in this area based on the soil environmental quality risk management and control standard.The results showed that the farmland soil in Wuhan East Lake High-Tech Development Zone was in a clean level,and there was slight Cd pollution in a small area(1.72%).There was no Pb,Ni,Cr,Cu,Hg,Pb pollution were found.
