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。
The article describes the survey and distribution of oil pollution in dredged materials in dredging areas of four dailies in China, including Dalian Bay, Tianjin Port, Shenzhen Bay and Zhujiang Reaches from 1988 to 1990. The paper introduces the principle of station layout, sample collection, sample processing, analysis and testing methods. The experiment of leaching dredged oil was carried out. It is considered that the oil dissolution experiment is an important method to evaluate the degree of pollution of dredged oil. Discussed 4 Harbor dredging oil pollution levels. The dredged material in the Dalian Bay area is obviously polluted. The dredged materials in the Pearl River, Shenzhen Bay and Tianjin Port are slightly affected and are basically clean.
