| 摘 要： | 采用Tessier形态分类法研究了小清河(济南段)底泥沉积物中痕量重金属元素Cu，Pb，Zn，Cr和Mn的存在形态，揭示了小清河(济南段)污染源的分布及相应重金属污染物的迁移转化，发现小清河源头底泥中重金属含量较低，流经济南市化工区后重金属污染物剧增、这是由于工业废水污染所致，底泥自净作用使小清河在郊区流出口处底泥污染物含量降回到接近本底值．

| Abstract: | The speciation of trace heavy metal pollutants such as Cu, Pb, Zn, Cr and Mn in Xiao-qing River sediments were studied by Tessier sequential extraction procedures, in order to reveal the distribution of pollutant sources and the remove transition pattern of the corresponding heavy metal pollutants. The results show that the quantity of heavy metals in Xiao-qing River beginning sediments are quite little, but increased drastically after flowing pass chemical industry region. The self-purification function of the sediments makes the quantity of the heavy metals in sediments fall back to the basic line near the exit of Xiao-qing River. |
