The levels of a 2,2',4,4',5,5'-hexabromobiphenyl (BB-153) were measured in human milk samples collected in 2007 and 2011 from residents in China by high-resolution gas chromatography-high-resolution mass chromatography (HRGC-HRMS) with isotope dilution. The median concentrations of BB-153 from the samples collected in 2007 and 2011 were 8.3 and 7.2 pg/g lipid weight, respectively. The levels of BB-153 in the human milk collected from rural areas were not significantly different to those collected from the urban areas in China. Meanwhile, significant positive correlations were found between the levels of BB-153 in human milk and the consumption of animal-origin foods. In the present study, the mean levels of BB-153 in human milk from Chinese mothers were found to be lower than those from European and American mothers.
采用高分辨率气相色谱-高分辨率质谱联用仪(HRGC-HRMS)和同位素稀释法,对2007年和2011年采集的中国居民母乳样本中的2,2',4,4',5,5'-六溴联苯(BB-153)水平进行了测定。2007年和2011年采集样本中BB-153的中位数浓度分别为8.3和7.2 pg/g脂重。在中国,农村地区采集的母乳中BB-153水平与城市地区采集的母乳中BB-153水平无显著差异。同时,母乳中BB-153水平与动物性食品的摄入量之间存在显著正相关。在本研究中,发现中国母亲母乳中BB-153的平均水平低于欧美母亲。
