洋河水库底泥重金属污染及其潜在生态危害评价OA
Heavy Metal Pollution and Potential Ecological Hazard Assessment of Yanghe Reservoir Sediment
为了解洋河水库底泥沉积物中重金属含量及其潜在生态危害程度,共采集了21个底泥样品,测试了镉、汞、砷、铜、锌、铅、镍、铬共8种重金属元素,采用地积累指数法和潜在生态危害指数法进行分析和评价,结果表明,洋河水库部分区域底泥存在重金属污染.
In order to understand the contents of heavy metals in the sediments of the Yanghe Reservoir and their poten-tial ecological risk,21 sediment samples were collected from the Yanghe Reservoir,and 8 heavy metals,in-cluding cadmium,mercury,arsenic,copper,zinc,lead,nickel and chromium,were tested.The geoaccumu-lation index method and the potential ecological risk index method were used to analyze and evaluate the heavy metal pollution of the Yanghe reservo…查看全部>>
