title: [Occurrence of synthetic musks in human milk samples collected from Beijing].
abstract: OBJECTIVE
  To investigate the occurrence of 13 kinds of synthetic musk and triclosan in breast milk samples collected from Beijing, and to estimate the exposure of breastfed infants.
  
  
  METHODS
  Target compounds in 65 milk samples collected from 4 districts of Beijing in 2004 were analyzed by means of gas chromatography - tandem mass spectrometry (GC - MS/MS) and quantified by internal standards. The exposure of infants was analyzed statistically by SPSS software.
  
  
  RESULTS
  HHCB, AHTN, OTNE, MT and Triclosan were detected in milk samples in the range of 0.6 - 174.1 ng/g lipid, with some difference in 4 districts. It is estimated that the intake of synthetic musks and triclosan for each infant from breast milk would be 13.5 - 3917 ng/d.
  
  
  CONCLUSIONS
  Commonly used synthetic musks and tricloson were generally detected in breast milk. Further study should be focused on monitoring and tracing the possible source of pollution.
