The Changjiang has transported large quantities of polycyclic aromatic hydrocarbons (PAHs) to the East China Sea (ECS), but information of these pollutants in zooplankton is limited. To understand PAHs pollution in zooplankton in the ECS, total concentrations of PAHs in zooplankton from surface waters were measured. Values of PAHs ranged from 2 to 3500 ng m(-3) in the ECS, with highest PAHs levels located at the salinity front between the Changjiang Diluted Water (CDW) and the mid-shelf waters. In contrast, concentrations of zooplankton PAHs in the mid-shelf and outer-shelf waters were significantly lower (2-23 ng m(-3)) than those in the CDW. These results demonstrate that PAHs are conspicuously accumulated in zooplankton at the salinity front between the CDW and the mid-shelf waters. These higher levels of PAHs in zooplankton at the salinity front may be further biomagnified in marine organisms of higher trophic levels through their feeding activities.
长江已将大量多环芳烃（PAHs）输送到东海（ECS），但浮游动物中这些污染物的相关信息有限。为了解东海浮游动物中的多环芳烃污染情况，对表层水域浮游动物中的多环芳烃总浓度进行了测定。东海浮游动物中的多环芳烃含量在2至3500纳克/立方米之间，其中多环芳烃含量最高的区域位于长江冲淡水（CDW）和陆架中部水域之间的盐度锋面处。相比之下，陆架中部和陆架外部水域浮游动物中的多环芳烃浓度（2至23纳克/立方米）明显低于长江冲淡水区域。这些结果表明，多环芳烃在长江冲淡水与陆架中部水域之间的盐度锋面处的浮游动物中显著积累。盐度锋面处浮游动物中较高水平的多环芳烃可能会通过其摄食活动在营养级较高的海洋生物中进一步生物放大。
