Babies are being exposed to “totally unacceptable concentrations”
Lynne Peeples reports for Environmental Health News
Bisphenol A and its substitute chemicals—pervasive in food and beverage containers, canned goods and store receipts—are showing up in mothers’ wombs at “unexpectedly high levels,” according to a new study published in the journal Environmental Science and Technology.
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.
“We are very clearly seeing these compounds going straight to the baby at totally unacceptable concentrations,” Terrence Collins, a green chemist at Carnegie Mellon University, who was not involved in the study, told EHN.
The study, published in March, looked for 15 different bisphenols—including a BPA, BPS and other popular substitutes—in 60 pairs of maternal plasma, cord plasma and placenta samples from pregnant women in South China. Four bisphenols were frequently detected in all three samples: BPA, BPS, BPAF and BPE.
BPSIP, a relatively new compound commonly used in thermal paper for store receipts, appeared at high levels in all maternal plasma samples. The researchers note that BPSIP “exhibits a similar estrogenic potency and greater reproductive toxicity than BPA.”
“This is another shriek from nature, ‘Stop throwing BPA, or things like it, at me,'” added Collins.
The study is concerning as BPA is a known endocrine disruptor, meaning it is capable of scrambling hormone signals, and has been linked to cancer, diabetes and infertility. In-utero BPA exposure has been shown to derail the normal growth of the brain and other organs and manifest later in life as early puberty or an increase in anxiety-related behaviors or attention deficit hyperactivity disorder (ADHD). Some replacements have been tied to similar issues including obesity and reproductive problems. The new study linked BPAF concentrations in cord plasma with both premature birth and low birth weight.
Most BPA replacements are created by tweaking the BPA molecule to form similar compounds. As a result, most pose similar health concerns. A 2017 study found that six substitutes used in products promoted as BPA-free had as much, if not more, of an estrogen-mimicking effect on human breast cancer cells as BPA.
