摘要
This paper takes the shallow sea in the Pear river delta economic zone as the study area.We took a test for the seven heavy metal elements(As、Cd、Cr、Cu、Hg、Pb、Zn) in the sediment samples of surface,and delineated geochemical anomalies areas according to the environmental background values of the survey area.The result show that high-value anomalies of As、Cd、Cr、 Pb and Zn appeared in Daya bay and in the northeast water of Macao.High value anomalies of Cu、Pb、 Zn appeared in the bay near Shenzhen area where the Pearl river approaching the sea.The element of low anomalies occurred near to the Xunliao bay and Shuangyue Bay in Huizhou city,Guangdong province.The cause of high value anomaly may contribute to location,coastal landforms and the Bay,in addition to the economic activities such as port construction and operation.The depositions of pollutants exist in the bays where the coastal currents were blocked,so high value anomaly took place.The element of low anomalies occurred near to the Xunliao bay and Shuangyue bay in Huizhou city,Guangdong province may attribute to the lower industrial level in these areas.
