A total of 43 surface sediment collected from rivers and the estuaries in the Pearl River Delta (PRD) region and Mirs Bay from the South China were analyzed for twelve halogenated flame retardants (HFRs) including polybrominated diphenyl ethers (PBDEs) using liquid chromatography-tandem mass spectrometer system. Their levels, spacial distribution, congener profiles and possible sources were investigated. Decabromodiphenyl ethane (DBDPE) was the predominant contaminant (1.520-1714ng/g dw) in the study area exceeding those of PBDEs (8.090-595.8ng/g dw), implying that DBDPE has been the predominant HFR products in this region in recent years in addition to PBDEs. Whereas the ratio of [DBDPE/BDE 209] varied among samples, this is indicative of different usage patterns of HFRs between PRD region and Mirs Bay. The PBDEs congener was dominated by BDE 209, with the average value accounting for 86.8% of the total PBDE in the sediment samples.
本研究采用液相色谱-串联质谱系统，对珠江三角洲（PRD）地区河流和河口以及大鹏湾的 43 个表层沉积物进行了 12 种卤代阻燃剂（HFRs）的分析，包括多溴联苯醚（PBDEs）。研究了它们的水平、空间分布、同系物分布和可能的来源。十溴二苯乙烷（DBDPE）是研究区域的主要污染物（1.520-1714ng/g dw），超过了 PBDEs（8.090-595.8ng/g dw），这表明除了 PBDEs 之外，DBDPE 近年来一直是该地区的主要 HFR 产品。然而，[DBDPE/BDE 209]的比值在不同的样品中存在差异，这表明 PRD 地区和大鹏湾之间 HFR 的使用模式不同。PBDE 同系物主要由 BDE 209 组成，其平均值占沉积物样品中总 PBDE 的 86.8%。
