摘要: 以武汉市江夏区农田土壤为研究对象,共采集149个土壤样品,分析其中8种重金属(Pb、Cd、Cr、Hg、As、Ni、Cu和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,江夏区农田土壤半数以上处于清洁水平,存在的污染主要为Cd污染,40.27%的农田土壤处于Cd污染状态,1%左右的农田土壤分别处于As、Ni、Zn污染状态,未发现农田土壤受到Cr、Cu、Hg和Pb的污染。

Abstract: A total of 149 soil samples were collected from farmland soils in Jiangxia district, Wuhan city. The contents of 8 heavy metals (Pb, Cd, Cr, Hg, As, Ni, Cu and Zn) were analyzed. The single factor pollution index and Nemerow synthetical 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 more than half of the farmland soils in Jiangxia distract were clean. The main pollution was Cd pollution, 40.27% of farmland soils were in the state of Cd pollution, about 1% of farmland soils were in the state of As, Ni and Zn pollution respectively, and no farmland soils were found to be contaminated by Cr, Cu, Hg and Pb.

Key words: farmland soils, heavy metal, pollution assessment, Jiangxia district, Wuhan city
