摘要
The occurrence and distribution of 10 heavy metals,Cd,Cu,Pb,Zn,Cr,Tl,V,Mn,Co and Ni in sediments collected from Xiangjiang River(Yueyang section) were analyzed.Meanwhile the potential ecological risks of these heavy metals were calculated and assessed using Index of geoaccumulation(Igeo) as well as Lars Hanson method.The results indicated that: 1) Xiangjiang River (Yueyang section) was heavily polluted by Cd,Zn,Mn and Cu; 2) RI values in this area varied from 369 to 698; and 3) the pollution characteristic of multi-metals in this section was mainly related to Cd.
