Measurable concentrations of PBDEs, PCBs, and DDE were detected in all placentas collected across three U.S.locations.Sampling delays of ≤48 h produced variations that are generally within ±50% of the initial concentration.rn The authors sincerely thank our fellow researchers of the Placenta Consortium, as well as all the woman who donated their placentas.This work was supported by the Eunice Kennedy Shriver NationalInstitute of Child Health and Human Development, and funded by the Office of the Director of the National Institutes of Health.
