| Abstract: | In order to study the pollution characteristics and ecological risk of Cd,Pb in the sediments of Da yuan du hydropower station of Xiangjiang River,18 sediments specimens were sampled from 6 sites.Total contents and chemical speciation and bioavailability of Cd,Pb were determined.The index of geoaccumulation and single factor were then employed to evaluated the pollution degree and classification of Cd,Pb in the sediments.The results indicated that there were very high contents of Cd,Pb accumulated in the se... |
