Aquatic biota including fish, shrimp and bivalves were collected from the Yellow River Delta (YRD), China to investigate the levels, composition profile and dietary exposure of polybrominated diphenyl ethers (PBDEs), decabromodiphenyl ethane (DBDPE) and dechlorane plus (DP). The concentrations of PBDEs, DBDPE and DP in the organisms ranged from 5.3 to 149, not detected (nd) - 49, and 0.5-29 ng/g lipid weight, respectively. Higher levels of PBDEs and DP were found in mullet (Liza haematocheila).PBDEs were the major pollutants and BDE 209 was the predominant congener of PBDEs suggesting the great production and application of deca-BDE in YRD. The average f values for different species were similar to or a little lower than that of the commercial DP, suggesting syn-DP might be selectively accumulated by the organisms. The estimated daily intake values of HFRs suggested consuming fish was the main pathway for the exposure of halogenated flame retardants.
从中国黄河三角洲（YRD）采集了水生生物，包括鱼类、虾类和双壳类，以调查多溴二苯醚（PBDEs）、十溴二苯乙烷（DBDPE）和十氯酮（DP）的水平、组成分布和膳食暴露情况。生物体内的 PBDEs、DBDPE 和 DP 浓度范围分别为 5.3 至 149、未检出（nd）至 49 和 0.5 至 29ng/g 脂质重量。在乌鱼（Liza haematocheila）中发现了更高水平的 PBDEs 和 DP。PBDEs 是主要污染物，BDE 209 是 PBDEs 的主要同系物，表明十溴二苯醚在 YRD 的大量生产和应用。不同物种的平均 f 值与商用 DP 相似或略低，表明 syn-DP 可能被生物体选择性积累。高持久性有机污染物的估计日摄入量值表明，食用鱼类是接触卤代阻燃剂的主要途径。
