摘要
为了研究伊通河表层沉积物中重金属污染特征,采集了6份表层沉积物样品,对沉积物中Cr、Ni、Cu、Zn、Pb的含量进行测定。分析了重金属的空间分布状况,对其污染程度和生态危害程度进行了评价,并分析了重金属的来源。结果表明:五种重金属具有相同的空间分布特征;S6采样点属于轻度污染,其余五个采样点无污染;六个采样点都属于低生态危害;Cr、Cu、Zn、Pb主要来源于交通源和工业源,Ni主要来源于自然源。
In order to study the pollution characteristics of heavy metals in surface sediments from Yitong River,six samples were collected,and the contents of Cr,Ni,Cu,Zn and Pb were determined.The spatial distributions of heavy metals were analyzed,the pollution and ecological harm were evaluated,and the sources of heavy metals were analyzed.Results showed that the five heavy metals had the same spatial distribution characteristics;S6 sampling point was light pollution,the other five sampling points were no pollution;Six sampling points were low ecological hazards;Cr,Cu,Zn and Pb were mainly from traffic and industrial sources,and Ni was mainly from natural sources.
