In an article published on March 18, 2020, Environmental Health News informed about a recent study published in the journal Environmental Science & Technology by researchers from Jinan University investigating the presence of BPA and 14 other bisphenols in maternal plasma, cord plasma, and placenta samples from 60 pregnant women. The study found that BPA, bisphenol S (BPS; CAS 80-09-1), bisphenol AF (BPAF; CAS 1478-61-1), and bisphenol E (BPE; CAS 2081-08-5) were frequently detected in all three matrices, with “unexpectedly high levels” of 4-hydroxyphenyl 4-isoprooxyphenylsulfone (BPSIP; CAS 95235-30-6) in all maternal plasma samples (second only to the levels of BPA). EHN writes that “the study builds on previous evidence that BPA and its common replacement BPS can pass through a mother’s placenta and is the first to show the same for a range of other replacements suggesting that fetuses are being exposed to a cocktail of chemicals linked to behavioral and reproductive disorders, among other health problems.” The organization previously published results from a year-long investigation into the U.S. Food and Drug Administration’s (FDA) management of science related to BPA (FPF reported).
