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。 The contents of heavy metals in the surface sediments of Kaowan ocean in the northeastern South China Sea were measured by atomic absorption spectrometry. The over-standard rates of cadmium and lead in each station reached 91.7% and 50%, respectively. The contents of copper and zinc were not over- . The comparison and regression analysis showed that the heavy metal contents in the surface sediments of Kaowan Ocean were at the middle level in coastal areas of Guangdong and showed homologous correlations. The element correlation diagram shows that the surface sediment of Kaozhou ocean has not been affected by cadmium and lead sources.
