1Free bisphenol A(BPA),BPA-Glucuronide(BPA-G),and total BPA concentrations in maternal serum and urine during pregnancy and umbilical cord blood at delivery显示文摘While adult exposure to total bisphenol A(BPA)has been well documented,developmental exposure to BPA and fetal exposure to the bioactive form(free BPA)remains poorly defined.Therefore,pregnant women(n?199)between 28 and 35 weeks of pregnancy were invited to participate in this study.Maternal serum free of hemolysis(n?189)and urine(n?112)were collected at third trimester and delivery along with umbilical cord blood(UCB)at delivery.Free BPA,BPA mono-glucuronide(BPA-G)and total BPA concentrations were measured using gas chromatography coupled with tandem mass spectrometry.Circulating concentrations of free BPA were quantifiable above the method detection limit(MDL?0.026 ng/mL)in approximately 34%of serum samples in the third trimester and 21%of samples at delivery whereas BPA-G and total BPA were quantified in 43 and 70%of third trimester and delivery samples,respectively.The geometric mean of free BPA,BPA-G and total BPA concentrations in maternal serum during the third trimester and at delivery were 0.62 ng/L andWarren G.Foster Cariton Kubwabo Ivana Kosarac Sandra Gregorovich Garima Aryal Kaela Coleman 2019Emerging Contaminants2019,5,1:2
