Abstract
应用--(210)Pb测年法测定珠江口的现代沉积速率,推算出不同层段的沉积物年龄,指出其现代沉积环境相对比较稳定;对该海区柱状沉积物的重金属之间、重金属与有机碳含量之间的相关性进行了分析,并对珠江口的重金属污染状况与其它海域及珠江口历史上的污染进行了比较。结果认为,近年来,珠江口重金属污染有加重的趋势,为加强珠江口的环境保护与治理提供理论上的依据。
 
The paper presents the modern sedimentary rate determined by 210 Pb from a core collected in the Pearl River Estuary.The results show that the modern dcpositional environment of the Pearl River is relatively stable.The relations between organic carbon and heavy metals, and among the heavy metals of the core sediments are discussed.In addition, by comparing the heavy metal pollution of the Pearl River Estuary with that in other water areas and with the historical data, one might find an aggravating trend of heavy metal pollution in the Pearl River Estuary in recent years.
