黄浦江沉积物重金属的污染及评价

Pollution and Assessment of Heavy Metals in Huangpu River Sediments

采用地积累指数法和潜在生态危害指数法对黄浦江沉积物中的重金属进行了评价研究,解释了两种评价方法结果存在差异的原因。两种评价方法的结果均表明,黄浦江砷污染严重,镉中等程度污染,且各个江段均受到了一定程度的污染。

Based on the principle of sedimentology and environmental behavior of heavy metals, the index of geoaccumulation and potential ecological risk index were used to evaluate heavy metals pollution in sediments of Huangpu River, Shanghai. The difference between these two methods was explained as well. Results showed that each section of the River has been polluted with As and Cd as the major heavy metal pollution.
