| 中文摘要 |
| 本论文根据重金属环境化学行为的特点, 应用沉积学原理, 对南沙河运粮河、杨柳河主要重金属污染状况进行了研究;并在国内首次采用瑞典国家环境保护局乌普萨拉本质实验室的Lars Hakanson指数法对重金属的潜在生态危害进行了评价研究.经过几年的调查研究与测试, 发现工业硫酸中含有较多的汞, 这是今后研究水体污染必须重视的一个问题. |
| 英文摘要 |
| 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. |
