摘    要:为了解佛山水道底泥的污染状况,对佛山水道底泥重金属的总体水平及其潜在生态危害进行了调查.结果表明,佛山水道底泥重金属的质量比处于较高水平,Hg的平均质量比达到背景值的20倍,As的平均质量比是背景值的2倍多.根据潜在生态危害指数法的评价结果,佛山水道底泥重金属对生态系统的危害已达到很强的程度;各种重金属的生态危害排序为:Hg>Cd>Pb>Cu>As>Cr>Zn,其中Hg的生态危害已达到了极强的程度.

关 键 词:底泥  重金属  潜在生态危害  佛山

Abstract:The present situations and ecological risk of heavy metal pollution of sediment in Foshan waterway were depicted based on the investigation and monitoring.The distribution of heavy metals has much to do with the hydrological conditions of the river and the distribution of pollution sources.The harm of heavy metals of sediment in Foshan waterway was appraised by the method of potential ecological risk index.The results demonstrate that the harm has reached a high degree.The potential risk order of elements are Hg>Cd>Pb>Cu>As>Cr>Zn.Among them,the harm of Hg to the ecological system is very serious.
Keywords:Sediment  Heavy metals  Potential ecological risk  Foshan
