摘要:

为揭示北京地区鸡蛋中多溴联苯醚(polybrominated diphenyl ethers,PBDEs)及其甲氧基衍生物(methoxylated polybrominated diphenyl ethers,MeO-PBDEs)的污染特征,本实验利用气相色谱-负化学电离源-质谱分析了北京地区65 个鸡蛋样品中12 种PBDEs及5 种MeO-PBDEs的污染水平与组成特征。结果表明,鸡蛋中ΣPBDEs和ΣMeO-PBDEs的含量水平分别为ND(未检出)~2.21 μg/kg(以全蛋湿质量计,下同)和ND~0.89 μg/kg,检出率分别为15.38%和4.62%,与国内外相关研究相比处于较低水平。PBDEs中BDE-71的检出质量浓度较高,MeO-PBDEs以MeO-85为主要检出成分,其中蛋黄中的PBDEs和MeO-PBDEs的检出种类数量及含量均高于蛋白。通过膳食风险评估,表明北京市售鸡蛋产品中PBDEs的污染水平和膳食暴露均在可接受的范围内。

Abstract:

The pollution levels and composition characteristics of 12 polybrominated diphenyl ethers (PBDEs) and
5 methoxylated polybrominated diphenyl ethers (MeO-PBDEs) in 65 egg samples from Beijing markets were examined by
gas chromatography-negative chemical ionization mass spectrometry (GC-NCI/MS) to explore their pollution characteristics.
The level of total PBDEs detected in egg samples was 2.21 μg/kg, and the level of total MeO-PBDEs were 0.89 μg/kg, which
were lower than other relevant studies in China and abroad. The relevance ratio of PBDEs and MeO-PBDEs were 15.38%
and 4.62% and these pollutants were dominated by BDE-71 and MeO-85. The kinds and levels of analytes in egg yolk were
higher than those in egg white. Pollution level and dietary risk assessment of PBDEs in eggs showed acceptable levels of
PBDEs in eggs from Beijing supermarkets.

Key words: egg, polybrominated diphenyl ethers (PBDEs) and methoxylated polybrominated diphenyl ethers (MeO-PBDEs), pollution level, dietary risk assessment
