摘要
为了解湘江湘潭段表层沉积物的重金属污染情况,采集湘江湘潭市出入境断面(左右两侧)4 个点位的表层沉积物,检测其 7 种重金属(Ni、Cu、Zn、As、Cd、Pb、Hg)的含量,采用行业内 3 种方法对沉积物中重金属的污染程度和潜在生态风险进行评价.研究表明,该区域底泥中重金属Cd的污染风险极高,同时Hg、As、Pb存在较大的污染风险.
Abstract
In order to understand the heavy metal pollution situation of surface sediments in Xiangtan section of Xiangjiang River,this study collects surface sediments from four points on the entry and exit section(left and right sides)of Xiangtan city,and detects the content of seven heavy metals(Ni,Cu,Zn,As,Cd,Pb,Hg),and uses three industry methods to evaluate the degree of heavy metal pollution and potential ecological risks in sediments.Research has shown that the pollution risk of heavy metal Cd in the sediment of this area is extremely high,and there is also a significant pollution risk of Hg,As,and Pb.
