摘　　要：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 potential ecological risk,21 sediment samples were collected from the Yanghe Reservoir,and 8 heavy metals,including cadmium,mercury,arsenic,copper,zinc,lead,nickel and chromium,were tested.The geoaccumulation index method and the potential ecological risk index method were used to analyze and evaluate the heavy metal pollution of the Yanghe reservoir.The results showed that the sediments in some areas of Yanghe Reservoir were polluted by heavy metals.
