| 摘 要： | 本文以上海市苏州河沉积物为研究对象,采用Tessier形态分析法研究了沉积物中重金属元素Zn、Cu和Hg的含量变化与形态分布,初步探讨了沉积特点,对苏州河底泥的进一步治理提供了参考.结果表明,样品中Zn 、Cu、 Hg的含量匀接近或高于生物有影响水平;Zn 、Cu分别主要存在于有机态和Fe-Mn氧化物态中,可交换含量较少;Zn 、Cu、 Hg含量随沉积物浓度的变化为:沉积物表层重金属含量较低并略有起伏,中部较高,底层较低.

| Abstract: | The content variation and distribution of heavy metals of Zn, Cu and Hg in the sediments of the Suzhou River in Shanghai have been studied by using the speciation extraction procedure outlined by Tessier and their sedimentation features have been basically discussed. The results show that the Zn, Cu and Hg contents of sediment samples are close to or higher than Organism Influencing Level in the sediments; Zn and Cu are mainly existed in organic matters and Fe-Mn oxides, with little in exchangeable association. The Zn,Cu and H g contents are changed from relative low in the upper part of the sediment,to relative high in the middle part and relative low in the lower part of the sediments. |
