  1. ND Due to a high percentage of non-detects, descriptive statistics were not reported
  2. NA Non-applicable (KM median and GM MLE of contaminants with less than 50 % of observations detected were not calculated)
  3. a PBDE 15, PBDE 17, and PBDE 25 were not detected in both maternal and cord blood samples. PBB 153, PBDE 28, PBDE 33, were not detected in the cord blood
