Paper Title:
Heavy Metal Pollution of River Sludge in Taiyuan
  Abstract

Samples of the sludge were collected from urban channels in Taiyuan city, and its pollution characteristics of heavy metals were researched. As the emphasis, the distribution regularity of five chemical speciation about Cd, Cr, Zn, Cu, Ni, Pb were analyzed. The results showed that the concentration of Ni, Zn, Cr over standard in various degrees. The residual metal fractions had a higher proportion for all heavy metals. Cd, Zn and Ni were predominantly associated with the carbonates bonded metal fraction and the organics-sulfide bonded metal fraction. Cu, Pb and Cr were predominantly bound to the organics/sulfide and Fe/Mn oxides, but their proportion are different. The bio-transportation index of Zn and Ni are larger than the others. This is the emphasis of heavy metal pollutions control for the local channels.
