title: [A survey on the dioxin level in breast milk in coastal and inland region].
abstract: OBJECTIVE
  To study the dioxin level of breast milk among Chinese mothers, and to assess the dioxin intake of new-born babies from mother's milk and compare with the Tolerable Daily Intake (TDI) of dioxin.
  
  
  METHODS
  The CALUX bioassay was used to detect the dioxin concentration of the first time mother's milk among the inland samples (Shenyang region; 32 cases) and the coastal city samples (Dalian region; 47 cases).
  
  
  RESULTS
  The median value of the dioxin Toxic Equivalence (TEQ) in breast milk in the Dalian region was 15.84 pg TEQs.g(-1) fat, which was significantly higher than that in the Shenyang region 7.21 pg TEQs.g(-1) fat (P < 0.01).
  
  
  CONCLUSIONS
  The dioxin level in breast milk in Chinese is at the world's average level. The dioxin intake of the new-born babies during the period of lactation was higher than the lowest limit of the Tolerable Daily Intake (TDI) proposed by WHO. This situation should be noticed by the related authorities.
