摘要
以地表堆积物中的Pb、Zn、Cu、Cd作为重点研究对象,在广州市分三个功能区(工业区、商业区、住宅区)进行地表堆积物样品的采集,从总含量、不同粒径级含量来分析堆积物中重金属的总体特性,并以研究结论为广州城市非点源的防治与管理提供理论依据。
Pb,Zn,Cu and Cd in urban surface sediment were taken as key objects in this study.Surface sediment in three functional areas(industrial area,commercial area and residential area) were collected.Total content and content in different grain sizes were analyzed to present the total characteristic of urban surface sediment.Sequent achievements can be taken as theoretical bases for controlling and managing non-point source pollution of Guangzhou.
