A suite of PBDEs and 2,4,6-TBP were measured in 102 placenta tissue samples.
BDE-209 was detected in more than 50% of the samples.
2,4,6-TBP was found in the highest concentrations in placenta tissue.
2,4,6-TBP was significantly correlated with PBDEs.
BDE-209 and 2,4,6-TBP were suggested to be negatively associated with maternal age.
