中文摘要	It has been reported that breastfeeding can expose newborns to dechlorane plus (DP), but transplacental transfer of DP has not been documented. We measured DP and its dechlorinated analogs in matched maternal blood-placenta-cord blood samples from 72 residents of the e-waste recycling area of Wenling, China. DP was detected in cord sera, indicating the occurrence of prenatal DP exposure and the transfer of DP across the placenta. The concentration ratio in the cord serum and maternal serum was estimated to be 0.45 for syn-DP and 0.35 for anti-DP, indicating the placenta partially limited DP transfer with a greater extent for anti-DP. The DP concentrations in the maternal serum, placenta, and cord serum strongly correlated, indicating that DP could transfer between the tissues. The DP concentrations in the matched samples could be predicted from each other. The anti-DP/total DP concentration ratios in the placentas and cord sera were significantly different from those in the maternal sera, suggesting that DP stereoselectively bioaccumulates in human tissues. When the congener concentrations of polybrominated diphenyl ethers (PBDEs) were used as control variables, DP and total triiodothyronine concentrations were associated in the sera from mothers who had lived in Wen ling for over 20 years.
