摘要
通过对上海黄浦江流域沉积物中几种典型重金属的含量水平、分布特征、污染情况进行了系统的研究与评价,并利用多元统计分析的方法对沉积物重金属的污染来源进行剖析。同时,通过分析黄浦江流域从上游至下游各河段污染的情况,厘清黄浦江沉积物重金属污染与上海市城市化进程之间的关联,对当前环境领域的重金属污染防治工作具有一定意义。研究结果表明,黄浦江沉积物中Pb,Zn,Cu,Cr,Cd,Sb的含量较高,均呈现从上游到下游污染加重的趋势;重金属总量的污染评价结果显示,黄浦江Cd污染最为严重,其次为Pb,Zn和Cu;多元统计分析方法结果表明,黄浦江沉积物中Mn,Co和Sr多为自然来源,Cu,Pb,Zn,Cd,Bi,As和Sb受人为活动影响较重,可认定为工业、农业及交通复合污染。
The typical heavy metals content,distribution and pollution status in sediment of Huangpu River were systematically investigated and the heavy metals sources in sediments were explored by using multivariate statistical analysis.To prevent the heavy metal pollution,it is important to clarify the correlation between the heavy metal pollution and the urbanization process of Shanghai through the analysis of pollution from upstream to downstream in Huangpu River.The results showed that the contents of Pb,Zn,Cu,Cr,Cd,and Sb in sediments of Huangpu River were relatively high and the trend of pollution were increased from the upstream to downstream.The pollution evaluation results displayed that Cd pollution was most serious in Huangpu River followed by Pb,Zn,and Cu according to the total amount of heavy metals.Multivariate statistical analysis indicated that Mn,Co,and Sr in sediments of Huangpu River were contributed from natural source;Cu,Pb,Zn,Cd,Bi,As,and Sb were significantly affected by human activities which were related to the combination of industry,agriculture,and transportation pollutions.
