摘    要:应用地累积指数法对珠江(广州河段)表层沉积物中重金属污染程度进行了调查与评价.结果表明,其表层沉积物中重金属的地累积指数大小顺序为:Cu>Cd>Zn>Pb>As>Cr>Hg,其中Cu是主要污染物,Cd、Zn和Pb的地累积指数较高.在所有监测断面中,地累积级别达到4级(强污染)的有5个断面,即4#(雅瑶大桥)、5#(黄歧)、6#(黄沙)、7#(横滘)和16#(花地涌北出口).

关 键 词:地累积指数  沉积物  重金属污染  珠江  珠江  广州  河段  表层沉积物  重金属污染调查  评价  Pearl  River  Section  Guangzhou  Surface  Sediments  Heavy  Metal  Pollution  Evaluation  出口  黄沙  大桥  监测断面  强污染  污染物  大小  地累积指数法

Abstract:The heavy metal pollution in Guangzhou section surface sediment of the Pearl River was studied with index of Geoaccumulation(Igeo).The results indicated the index of heavy metals in the surface sediment decreases as followed: Cu>Cd>Zn>Pb>As>Cr>Hg.Cu is the main pollutant and the Igeo of Cd,Zn and Pb are larger than that of others elements.There are 5 sampling sites whose Igeo get scale 4,which means heavy pollution,and they are 4#(The bridge of Yayao),5#(Huangqi),6#(Huangsha),7#(Hengjiao) and 16#(The north exit of the Huadi Stream).
Keywords:Index of geoaccumulation  Sediment  Heavy metal pollution  Pearl River
