Cohort study suggests maternal exposure to some phosphorus ester FRs may impact baby’s size at birth. 16 organophosphorus ester FRs or metabolites were repeatedly measured in urine of 213 pregnant women in Wuhan, China. bis(1,3-dichloro-2-propyl) phosphate (BDCIPP, a metabolite of TDCPP), bis(2-butoxyethyl) phosphate (BBOEP), 4-hydroxyphenyl-diphenyl phosphate (4-HO-DPHP) and diphenyl phosphate (DPHP) concentrations in the typical range of 0.5 – 5 ng/mL showed some correlations to baby birth weight or length at birth.
