摘要

The levels of a 2,2', 4,4', 5,5'-hexabromo biphenyl (BB-153) were measured in human milk samples collected in 2007 and 2011 from residents in China by high-resolution gas chromatographyhigh-resolution mass chromatography (HRGCHRMS) 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.
