摘要：

吴淞口附近码头众多，溢油导致岸边沉积物遭受污染.从平面和纵向上研究吴淞口近岸沉积物中油类污染物的含量、组成及分布特征.结果表明：吴淞口近岸沉积物中存在着不同程度的油类污染，总石油烃(total petroleum hydrocarbon,TPH)质量比为8~1 166 mg/kg；沉积物中油类污染物的链烃碳数为C16~C33，且主要分布在C25~C32范围内，其中主峰碳数为C31，链烃污染物具有明显的奇偶优势特征.研究显示，吴淞口近岸沉积物油类污染严重，且非均质性强，溢油来源主要为陆相石油及其制品.

关键词: 吴淞口；沉积物；总石油烃

Abstract:

There were numerous wharfs in Wusong Estuary, where the sediments had been polluted by oil spills. The amount, composition and distribution characteristics of oily pollutions in the Wusong Estuary sediments were analyzed in horizontal and vertical directions. It showed that the sediments in the Wusong Estuary had been polluted to various degrees, the content of total petroleum hydrocarbon (TPH) in the sediments was 8~1 166 mg/kg. The carbon number range of chain hydrocarbons were C16~C33 in the oil pollutants, mainly by the composition C25~C32. Peak carbon of chain hydrocarbons is C31. It showed oddeven predominance. The research shows that the coast sediments at Wusong Estuary have been seriously polluted by heterogeneous oily pollutants, and the oil spill mainly originated from the terrestrial petroleum and its products.

Key words: Wusong Estuary; sediment; total petroleum hydrocarbon （TPH）
