There is increasing concern regarding human exposure to bisphenol analogues (BPs) due to their widespread use and potentially adverse effects. Nevertheless, information on the occurrence of BPs in pregnant women is limited. In this study, BPs were detected in 181 serum samples from pregnant Chinese women. Ten BPs, including bisphenol S (BPS), bisphenol F (BPF), bisphenol AF (BPAF), bisphenol B (BPB), bisphenol P (BPP), bisphenol Z (BPZ), bisphenol AP (BPAP), tetrabromobisphenol A (TBBPA), tetrabromobisphenol S (TBBPS), and tetrachlorobisphenol A (TCBPA), were positively identified and quantified in serum samples with total BP concentrations (sum of bisphenols: ∑BPs) of 0-144 ng/mL. Concentrations of the two frequently detected compounds, TBBPS and BPS, were 0.593 and 0.113 ng/mL, respectively. The results were also compared with the geographic distributions of the BPs. To our knowledge, this is the first time that TBBPS and TCBPA have been detected in serum samples of pregnant women. These findings suggest that additional studies are urgently needed to identify the risk of maternal and fetal exposure to these compounds.
