Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants whose use has contaminated foods and caused subsequent human exposures. To address the issue of possible human exposure, samples from a 2012-13 US meat and poultry (beef, pork, chicken, turkey) study were analysed for seven PBDEs. The mean summed concentrations of the seven BDE congeners (ΣPBDE) from beef, pork, chicken and turkey were 0.40, 0.36, 0.19, and 0.76 ng g lipid weight (lw). The range of ΣPBDEs for all meat classes was 0.01-15.78 ng g lw. A comparison of this study with a 2007-08 study revealed a decline in the median ΣPBDEs for all four meat classes, a reduction of 25.9% to 70.0%, with pork, chicken and turkey PBDE residues being statistically lower relative to the 2007-08 study. BDEs 47 and 99 contributed the most to the ΣPBDE concentrations, indicating likely animal exposures to the penta-BDE formulation. Based on the reported data an estimate of US consumer daily intake of PBDEs from meat and poultry was 6.42 ng day.
多溴二苯醚（PBDEs）是一类溴化阻燃剂，其使用已污染食物并导致人类后续接触。为解决可能的人类接触问题，对2012 - 13年美国肉类和家禽（牛肉、猪肉、鸡肉、火鸡）研究中的样本进行了7种多溴二苯醚的分析。牛肉、猪肉、鸡肉和火鸡中7种二苯醚同系物（ΣPBDE）的平均总浓度分别为0.40、0.36、0.19和0.76纳克/克脂质重量（lw）。所有肉类的ΣPBDEs范围为0.01 - 15.78纳克/克lw。将本研究与2007 - 08年的研究进行比较发现，所有四类肉类的ΣPBDEs中位数均有所下降，降幅为25.9%至70.0%，猪肉、鸡肉和火鸡中的多溴二苯醚残留量相对于2007 - 08年的研究在统计学上更低。BDE - 47和BDE - 99对ΣPBDE浓度的贡献最大，表明动物可能接触到五溴二苯醚配方产品。根据报告数据，美国消费者从肉类和家禽中每日摄入多溴二苯醚的估计量为6.42纳克/天。
