某乳业厂拆迁场地土壤重金属污染特征及健康风险评价
|
摘要
以乳业厂拆迁场地土壤为研究对象,共采集12份土壤样品,采用单因子污染指数法、内格梅罗综合污染指数法、健康风险评价模型对该场地土壤重金属污染状况及人体健康风险进行研究,结果表明:土壤中的Cd、Hg、As、Pb、Cr、Cu、Ni、Zn 8种重金属含量均超过了广东省土壤元素背景值,从变异系数来看,Cd、Cu、As变异系数较大,同时Cd、Cu、Zn为重污染;As和Pb为中度污染; Hg,Cr,Ni污染较轻; As对儿童存在较强致癌风险。
A total of 12 soils from demolition of dairy factory were collected and analyzed. By using the single factor pollution index method combined with the case and the comprehensive pollution index method,the soil heavy metal pollution characteristics and human health risk were studied. These results showed that the contents of Cd,Hg,As,Pb,Cr,Cu,Ni and Zn in the soil of the site all exceeded the background value of soil elements in Guangdong province. From the point of variation coefficient,spatial variation of Cd,Cu and As was significant. Meanwhile,Cd,Cu and Zn were heavy pollution,As and Pb were moderate pollution,Hg,Cr and Ni were light pollution,and As had a strong carcinogenic risk to children.
