| 摘 要： | 采用气相色谱测定了吕四渔场水质和沉积物样品中的多氯联苯(PCBs),并分析了其分布特征。结果显示,吕四渔场水质和沉积物中的PCBs平面分布特征为南部近岸高,而北部近岸较外海低,调查海域PCBs含量有逐年升高的趋势。水质中以低氯代PCBs同族体为主,沉积物中以高氯代PCBs同族体为主,含6个氯原子的PCBs在水中和沉积物中含量都比较高。为了削减PCBs对环境和人类的危害,我们要加强控制、管理、研究和合作。

| Abstract: | Polychlorinated Biphenyls（PCBs）in seawater and sediments of Lvsi fishing ground was determined by GC method,and characteristic of Polychlorinated Biphenyls （PCBs） in the area was analyzed. The results showed that the horizontal distribution of PCBs in seawater and sediments of Lvsi fishing ground is relatively high in inshore area of south zone and offshore area of north zone. PCBs of survey waters were increased year by year. Low chlorinated PCBs congener were the major components in seawater of Lvsi fishing ground, High chlorinated PCBs congener were the major components in sediments. C16- PCBs were the major components in seawater and sediments. In order to reduce the harm of PCBs to environment and human,We must strengthen the control, man- agement, the research and cooperation. |
