柴油在海洋底栖围隔生态系中的分布及其变化

Distribution and change of diesel oil in enclosed marine benthic ecosystem

本文论述了不同浓度的沙柴油污染海洋底栖围隔生态系后，在各相中的分布及其变化。实验结果表明：柴油添加后20h，底质油含量与水体油污染含量成正相关；菲律宾蛤行（Ruditapesphilippinarum）对柴油有较强的富集能力。柴油中短链正构烷烃（C8～C15）较易消失。柴油对底栖生态系的影响周期较长。

It reports the distribution and changes of No. 0 deisel oil in different phases after exposein the enclosed marine benthic ecosystem. The experiment shows that the contents of oil inthe sediments are positively related to the contents in the water after 24h exposure. ClamRuditapes philippinarum concentrared high amount of oil. Short chain components (C8 ~C15) of alkanes of the diesel oil disappeared firstly. The effects of oil on the benthicecosystem remained for a long period.
