The residents of Shandong Province, China, are exposed to high concentrations of halogenated flame retardants because large amounts of halogenated flame retardants are produced in the province. We determined the concentrations of eight polybrominated diphenyl ether congeners (PBDEs), seven novel brominated flame retardants (NBFRs), and the two dechlorane plus isomers (DPs) in serum from residents of Shandong Province. The aim was to identify temporal trends in the concentrations of these pollutants. The mean total concentrations of PBDEs, NBFRs and DPs were 41, 2.2 and 2.1ng/g lipid in pooled serum samples collected in 2014, and were 32, 3.5 and 3.1ng/g lipid in pooled serum samples collected in 2015, respectively. Decabromodiphenyl ether was the dominant PBDE congener in all of the samples. The novel brominated flame retardant and dechlorane plus concentrations were between one and two orders of magnitude lower than the PBDE concentrations. The PBDE concentrations in serum decreased significantly between 2007 and 2015, but the pentabromobenzene, pentabromotoluene, and dechlorane plus concentrations were relatively stable.
中国山东省居民暴露于高浓度的卤代阻燃剂中，因为该省生产了大量的卤代阻燃剂。我们测定了山东省居民血清中 8 种多溴联苯醚同系物（PBDEs）、7 种新型溴化阻燃剂（NBFRs）和 2 种十氯酮加合物（DPs）的浓度，旨在确定这些污染物浓度的时间趋势。2014 年采集的混合血清样本中，PBDEs、NBFRs 和 DPs 的平均总浓度分别为 41、2.2 和 2.1ng/g 脂质，2015 年采集的混合血清样本中，PBDEs、NBFRs 和 DPs 的平均总浓度分别为 32、3.5 和 3.1ng/g 脂质。十溴二苯醚是所有样本中 PBDE 同系物的主要成分。新型溴化阻燃剂和十氯酮加合物的浓度比 PBDE 浓度低 1 到 2 个数量级。血清中的 PBDE 浓度在 2007 年至 2015 年间显著下降，但五溴甲苯和十氯酮的浓度相对稳定。
