Concentrations of polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and polybrominated diphenyl ethers (PBDEs) were measured in 32 species inhabiting the Yellow Sea to assess their bioaccumulation potentials. The concentrations in these samples were lower than those reported for other countries or locations. Relatively high levels of BDE 209 in biota suggest an ongoing source of deca-BDE technical mixing within the Yellow Sea. The accumulation profiles of PCBs were uniform between species, but the concentrations of OCPs and PBDEs varied widely. Pelagic and benthic food-chain components were separated by their δ(13)C values. Significant positive correlations between δ(15)N and PCB 153, PCB 138, p,p'-DDE, oxy-chlordane, and trans-nonachlordane were found only for pelagic consumers, indicating that the pelagic food chain is an important bioaccumulation pathway for selected PCB and OCP compounds. The other compounds did not show any biomagnification through benthic and pelagic food chains, suggesting the lower bioaccumulation potentials of these contaminants.
研究人员测定了栖息于黄海的 32 种物种体内的多氯联苯（PCBs）、有机氯农药（OCPs）和多溴二苯醚（PBDEs）的浓度，以评估它们的生物累积潜力。这些样本中的浓度低于其他国家或地区的报告值。生物体内相对较高水平的 BDE-209 表明，十溴联苯醚技术混合物在黄海内仍在持续生成。PCBs 的累积分布在物种间是均匀的，但 OCPs 和 PBDEs 的浓度差异很大。浮游和底栖食物链成分通过其 δ(13)C 值进行区分。仅在浮游消费者中发现 δ(15)N 与 PCB-153、PCB-138、p,p'-DDE、氧氯丹和反式-非六氯丁二烯之间存在显著的正相关关系，表明浮游食物链是某些 PCB 和 OCP 化合物的重要生物累积途径。其他化合物则没有通过底栖和浮游食物链显示出任何生物放大作用，表明这些污染物的生物累积潜力较低。
