我国四个港湾疏浚物石油污染

文中叙述了１９８８￣１９９０年间，我国４个港湾－大连湾、天津港、深圳湾及珠江河段各疏浚区疏浚物中油类污染调查及分布状况。文中介绍了站位布设原则，样品采集、样品处理、分析测试方法。进行了沾污疏浚物油类出溶出实验，认为油类溶出实验是估价疏浚物油类污染的程度的重要手段。讨论了４港湾疏浚物油类污染水平。大连湾海域疏浚物石油污染明显，珠江河段，深圳湾及天津港疏浚物稍受影响，基本上是清洁的。

Oil Pollution in the Dredged Materials in the Four Harbours in China

Oil pollution condition and degree in the dredged areas from 1988 to 1990 were described and evaluated in the paper.The dredged areas described here were Dalian Bay,Tianjin Harbour.Shenzhen Bay,and Zhujiang Estuary.The principle of sampling station choice,sampling,sample treatment and determination method were introduced briefly.Oil pollution level was discussed.The oil-release simulated experiment from the dredged materials to seawater was made in laboratory.It should be pointed out that the significant difference of the results was calused by the different detection technique (UVand FLU).
