Objective:
To evaluate the burden of polybrominated diphenyl ethers (PBDEs) in general people and the exposure of infants via breast feeding in Beijing, the levels of PBDEs in human milk samples from Beijing were investigated.
Method:
Seven congeners of PBDE, including BDE28, BDE47, BDE99, BDE100, BDE153, BDE154 and BDE183 in pooled breast milk samples and 40 individual breast milk samples, were measured with HRGC-HRMS.
Result:
Seven selected congeners of PBDEs were all detected in samples. The mean and median concentration was 1.48 ng/g and 1.51 ng/g respectively. BDE47, BDE153 and BDE28 were the predominant congeners, accounted for 80% of total PBDEs. PBDEs in breast milk from urban areas were higher than that from rural areas.
Conclusion:
PBDEs in breast milk samples from Beijing were much lower than that from other areas. Further monitoring will be important to determine the variation of PBDE levels and elucidate the contamination status.
