Application of Sedimentologieal Principle to Appraisal of Heavy Metal Pollution and Potential Ecological Risk in the Affluents of the Taizihe River, Northeast China
应用沉积学原理评价太子河支流主要重金属污染及潜在生态危害

Based on the principle of sedimentology and theenvironmetal behavior characteristics of heavy metals, this paper reports heavy metal pollution in the main affluents of the main affluents of the Taizihe River, namely, the Nanshahe River, Yunlianghe River and Yangliuhe River in Liaoning Province. In the research, the potential ecological risk index presented by Lars Hakanson of Upsala Water Quality Laboratory, Swedish National Environmental Protection Board, was first applied to assess potential ecological impact of heavy metals in China. This research reveals that industrial sulphuric acid contains fairly high content of mercury, which may be an important source of water pollution. So this source must be taken into account for further study on water pollution.
