Results
Women participating in our study ranged in age from 28 to 36 years at conception and were predominantly white (88%) and highly educated (88% had completed graduate education). All mothers delivered healthy, full-term infants. Both BDCPP and DPP were detected in nearly all urine samples (97% detect); however, geometric mean urine concentrations varied considerably from individual to individual. The distribution of BDCPP and DPP concentrations in urine samples is shown in Table 1 (n = 39). Levels of BDCPP and DPP at each time point were weakly correlated (rs = 0.3, p = 0.1).
