Paper Title:
Study on the Heavy Metal Sediment Pollution and Ecological Effect in Yin-Dong Liang Mine Area
  Abstract

In the paper, the total contents of Pb, Zn, Cd, Cu, Cr in sediment samples which were systematically collected from Yin-dong Liang lead-zinc mine area located at Feng country in Shaanxi province were determined by air-acetylene flame atomic spectrophotometer and the morphology of heavy metal in sediment was further investigated. Based on system testing, pollution load index was applied to assess the pollution situation of sediment. The results show that the pollution load index of mine area was up to 14.22, indicating the pollution situation is severe. Moreover, the most heavy metals are in residual state in comparison with the less water soluble, leading to relative low bioavailability and ecological risk. However, the higher proportion of reducible and oxidizable could be released to the environment under appropriate conditions, resulting in severe potential ecological risk.
