| Abstract: | The chemical speciation of eight heavy metals(Cd,Pb,Cu,Cr,Zn,Ni,Fe and Mn) in sediments from Hongfeng Lake,the largest man made lake on the Guizhou Plateau,was studied based on the Tessier sequential fractionation.Both the ratio of secondary phase to primary phase(RSP) and secondary phase enrichment factor(SPEF) were employed to assess heavy metal pollution in sediments,and the outcome of these two assessment methods was compared and analyzed.The results obtained in this study are as follow: Mn and Cd in th... |
