目的：了解北京市市售动物性食品中十溴联苯醚和六溴环十二烷异构体(α-，β-，γ-六溴环十二烷)的污染水平。方法于2013年采集北京地区水产品、肉、蛋、奶等动物性食品。采用凝胶渗透色谱结合固相萃取技术进行样品前处理，以气相色谱-负化学源质谱法(GC-NCI-MS)及超高效液相色谱-电喷雾电离-串联质谱法(UPLC-ESI-MS/MS)结合稳定性同位素稀释技术分别测定食品中十溴联苯醚和α-，β-，γ-六溴环十二烷的含量。结果十溴联苯醚污染水平在ND 至159.17 ng/g 脂肪，平均值和中值分别为14.33 ng/g 脂肪和9.44 ng/g 脂肪。3种六溴环十二烷异构体总量在ND至26.83 ng/g 脂肪，均值和中值分别为4.32 ng/g 脂肪和2.45 ng/g 脂肪，α-六溴环十二烷是最主要的异构体。相比有关文献报道结果，本研究发现北京市市售动物性食品中十溴联苯醚和六溴环十二烷污染水平高于其他地区。结论北京市市售动物性食品中普遍存在十溴联苯醚和六溴环十二烷污染，应当持续开展此类溴系阻燃剂的污染水平监测和健康效应评估。

Objective To investigate the pollution levels of two brominated flame retardants, hexabromocyclododecane (HBCD) and decapolybrominated diphenyl ethers (BDE-209), in food samples of animal-origin saled in Beijing’s markets. Methods Aquatic foods, meat and meat products, eggs and dairy products, etc were colledted in 2013. The samples’ pretreatment were based on gel permeation chromatography combined with solid phase extraction. The BDE-209 was analyzed using GC-NCI-MS and theα-,β-,γ-HBCD was analyzed using UPLC-ESI-MS/MS. Results The pollution level of BDE-209 was from ND to 159.17 ng/g lipid, the mean value was 14.33 ng/g lipid and the median value was 9.44 ng/g lipid. The pollution level of HBCD was from ND to 26.83 ng/g lipid, with a mean and median value of 4.32 and 2.45 ng/g lipid, respectively.α-HBCD dominated the HBCD profile in the majority of the food samples. The pollution levels of BDE-209 and HBCD in present study were higher than other studies. Conclusion BDE-209 and HBCD are wildspread in the food of animal origin saled in Beijing’s markets. Further investigation and assessment of health effects to these brominated flame retardants are needed.
