摘要
通过对南水北调东线一期工程黄河以北段输水干线及其相关河道底泥重金属进行地累积指数污染评价、潜在生态危害评价,得出黄河以北段输水干线及其相关河道底泥中重金属汞表现为中度污染和中等生态危害程度的结论,并提出了水质保护建议。
Assessing the geoaccumulation index and the potential ecological risk, and analyzing the relativity of heavy metals in sediment in the Eastern Route of South-to-North Water Transfer Project and interrelated rivers by northward of Yellow River, we conclude that the heavy metal pollution and potential ecological risk are in medium degree and suggest water quality protection.
