Mothers and Newborns Found to Absorb BPA Substitutes Commonly Used in Everyday Products

New research on BPA substitutes suggests that mothers and their newborns are absorbing chemicals commonly used in consumer products.

The study appears to be the very first study to explore in utero exposure to bisphenol-A (BPA) substitutes and the first U.S. study to test for BPA and BPA substitutes in maternal/fetal pairs.bpa substitutes study

BPA Substitutes

BPA is a common ingredient in polycarbonate plastic and epoxy resins used in consumer products — like thermal receipts, dental sealants, and food packaging. In 2012-2013, the U.S. eliminated BPA from baby bottles and the linings of infant formula cans — frequently switching to BPA substitutes.

In recent years, BPA use has widely been replaced in consumer products by substitute chemicals like BPB, BPE, BPF, BPS, and BPAF. Recent studies have linked these BPA substitutes to similar unfavorable health outcomes as BPA — including disruption of endocrine pathways in animal and human studies.

Testing BPA Substitutes

Many polycarbonate products, from water bottles to children’s toys, are marketed as “BPA-free.”  However, many of these products use BPA substitutes.  Investigators at The Deirdre Imus Environmental Health Center® at Hackensack Meridian Health Hackensack University Medical Center collaborated with investigators at Rutgers University, in performing innovative tests on exposure to BPA and BPA substitutes in mothers and newborns.

Investigators from the Environmental and Occupational Health Sciences Institute at Rutgers University created a novel method to detect BPA and BPA substitutes, such as BPB, BPE, BPF, BPS, and BPAF in human blood and urine.

This new testing method was run on 30 paired maternal urine and fetal cord blood samples from mothers undergoing elective Caesarean sections. Ninety percent of mothers and 77 percent of babies tested positive for at least one BP chemical.

Lawrence Rosen, MD, integrative pediatrician and one of the paper’s authors cautions the public.

“These findings are of great concern for our most vulnerable little ones. We must continue to investigate what risks these chemicals pose for moms and babies.”

Further Warnings

Additionally, the BPA substitute study showed that 83 percent of mothers tested positive for BPAF, 60 percent for BPS, 57 percent for BPB, 17 percent for BPF and 7 percent for BPA.  Fifty-seven percent of babies tested positive for BPAF and 50 percent for BPF. BPA and BPB were detected in one cord blood sample each.

Brian T. Buckley, PhD, executive director of Laboratories and Administration at Rutgers University’s Environmental and Occupational Health Sciences Institute, also worked on this new study.

Dr. Buckley elaborates on this new and innovative testing method.

“Identifying how many individuals have measurable levels of a chemical is one way we estimate exposure and this new analytical method was created for just that purpose.  This was the first study to look at BPA alternatives in this population and I look forward to follow-up toxicological studies to get a true understanding of potential risk.”

Deirdre Imus, founder and president of The Deirdre Imus Environmental Health Center® at Hackensack University Medical Center, which sponsored the study, offers alternatives to avoid chemical exposure.

“We need to protect mothers and newborns from chemical exposures by encouraging moms to avoid exposures whenever practical, such as switching to glass and stainless steel food and beverage containers. Simple steps can make a difference.”

This new BPA substitutes study, titled “Application of a novel mass spectrometric (MS) method to examine exposure to Bisphenol-A and common substitutes in a maternal fetal cohort,” was published in Human and Ecological Risk Assessment.
