Abstract
The survey and analysis on heavy metal (Cu,Zn,Pb,Cd) in seawater were carried out fromMarch of 2008 to January of 2009 in Zhanjiang harbor. The results showed that the concentrations ofCu,Zn,Pb,Cd were low as a whole for a year round in 2008, with respectively average values of0.00446mg/L,0.0142mg/L,0.000795mg/L,0.000588mg/L, and the concentrations of Cu,Zn,Pb,Cd in thebottom seawater showed a slight higher than that in the surface for most stations. As for seasonalchange,the content of Cu followed a change rule of autumn＞spring＞summer＞winter, while Zn followedwith a rule of summer＞spring＞autumn＞winter,and Pb followed a rule of autumn＞summer＞spring＞winter,and Cd followed a rule of winter＞summer＞spring＞autumn .The contents of Cu,Zn,Pb,Cd were the highestin the central area ,besides the content of Zn, Cd in inner bay were rather high. Based on the assessmentresults with the single factor of pollution index, the water quality in Zhanjiang harbor was good.关键词
