Analysis of Heavy Metal Pollution in Sediment of Xiangtan Section of Xiangjiang River
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.
