An Alphabet of Bisphenols – BPA-Free, but BPS, BPF, BPZ, and more still included…

The Myth of BPA-Free Plastic

Many of us feel reassured when we grab a plastic bottle to drink from if it has a sticker that says “BPA free”. However, mounting evidence is showing that the replacements for BPA might be just as harmful.

My husband and I recently got ourselves tested for different toxins in our bodies through Silent Spring InstituteWe were both low on many of the toxins tested for but the one place where we differed was in BPS.

BPS Test Results for Matt Price

Matt’s results were higher than the US median on this one chemical.

Comparing US Median & Study Median Results

I found it interesting that of all of the study results I saw, this was the one chemical where the average of the people participating in the study was higher than the US median as well. On most chemicals, the average of the participants was lower than the US average, which is what you would expect from people knowledgeable enough about environmental toxins to take this test in the first place. I find it extremely interesting that on BPS, the participants were higher. I believe it might be because, like my husband, many participants look for the BPA-free label on plastics and believe they are okay with the plastics they are choosing. It is possible that BPS is being used as the replacement in water bottles labeled as BPA-free.

Bisphenols in Common Items

Bisphenols A, S, and F (BPA, BPS, and BPF), as well as additional bisphenols, are used primarily to make plastics and epoxy resins and coatings. BPA is found in some polycarbonate plastics, linings for aluminum food and beverage cans, and thermal receipt paper. BPS, sometimes used as a substitute to BPA, is commonly found in thermal receipt paper and is an ingredient in polycarbonate alternatives such as polyethersulfones. BPS and BPF have also been detected in canned food and beverages.

Bisphenol exposure has been associated with reproductive disorders, cancer, neurodevelopmental problems and asthma.

New Legislation Coming to New York

Legislation might soon address this issue. The state of New York recently introduced a bill that would expand the “Bisphenol A-free Children and Babies Act” of 2010 to cover several common BPA substitutes. Current law prohibits the sale of any children’s products containing BPA, but does not prohibit substitution of related chemicals that have similar structure and can cause similar health harm. The new legislation, scheduled to go into effect on December 31, 2019, was initiated after a recent study showed the estrogenic effects of six different bisphenols. The state amendment will expand the existing ban to now include: bisphenol AF, Z, S, F, AP, and B.
