| 摘 要： | 用原子吸收光谱法测定了南海东北部考洲洋表层沉积物中重金属的含量，各测站镉和铅含量超标率分别达到91.7%和50%，铜、锌含量未见超标，镍含量较低，比较和回归分析表明，考洲洋表层沉积物重金属含量在广东沿海居中等水平，并表现出同源相关关系，元素相关图显示，考洲洋表层沉积物尚未受人为来源镉和铅的影响。 |

| Abstract: | :The heavy metal contents in the surficial sediments in Kaozhou Bay were d etermined by means of atom absorption spectrometry.The c ontents of cadmium and lead,92%and 50%at 12sampling sites respec-tively,were more than the reference standards,but those of copper and zinc at all the sites were less than the reference standards,and nickel con tents were low.All 5metal elements m ight come from the similar source based upon our correlation analyses.Comp arison with other coastal areas indi cated that the levels of metal conten ts in the sediments of the Bay were medium i n Guangdong.According to the elemen ts -relation charts,the surficial sediments of Kaozhou Bay were not con taminated by artificial cadmium and lead. |
