Average serum unconjugated BPA levels in maternal and fetal serum over the 24 h between GD 17 and 18 (AUC0–24/24 h) after the last oral administration of 3H-BPA on GD 17. Pregnant females were fed a 20 μg/kg mixture of BPA and 3H-BPA one time per day between GD 11 and 17. Data for each BPA dose are based on linear interpolation, since administered dose is linear with internal serum concentration over a wider range of doses than were examined in this study [32].
