| 摘 要： | 对扬州古运河底泥重金属污染潜在生态危害进行了调查与评价。结果表明,古运河各监测断面的潜在生态危害指数等级为轻微至强。经综合整治,2002年后古运河重金属污染潜在生态危害指数较2002年之前显著下降。下游因曾经工厂聚集,污染程度高于上游,毒性系数较大的Cd和Hg的潜在生态危害始终排在首位。

| Abstract: | In order to evaluate potential ecological risk, heavy metal pollution in sediment of the Yangzhou Ancient Canal was investigated. Results showed that levels of ecological risk index were from low to high. The risk index of the Canal from 2002 dropped significantly by environmental comprehensive renovation project. Downstream pollution of the river was higher than that of the upper. Cd and Hg of high toxicity coefficient con- sistently listed on top of potential ecological risks |
