Researchers at Washington State University were investigating the reproductive effects of BPA in mice when they stumbled on a new find. Their experiment had mice housed in BPA-free plastic cages and the test group got doses of BPA through a dropper; the control group didn't. In fact according to an article published in National Geographic, geneticist Patricia Hunt was quoted as saying:
Our control data just started to get really wonky. The differences between it and the test group vanished, and many control mice started showing genetic issues.
Apparently some of the plastic caging were damaged and were leaching bisphenol S, or BPS—an alternative to BPA.
Close to 20 yrs ago Hunt had been researching BPA and had the same issue with polycarbonate in mouse cages.
Hunt went on to say that:
It was like déjà vu...
Switching gears Hunt decided to begin researching replacements to BPA to see if they had the same impact on reproduction in mice. Her current publication in [Cell Press](https://www.cell.com/current-biology/fulltext/S0960-9822(18%2930861-3) addresses the findings.
Our data show that exposure to common replacement bisphenols induces germline effects in both sexes that may affect multiple generations. These findings add to growing evidence of the biological risks posed by this class of chemicals. Rapid production of structural variants of BPA and other EDCs circumvents efforts to eliminate dangerous chemicals, exacerbates the regulatory burden of safety assessment, and increases environmental contamination.
This new research could suggests that variants of BPA and other EDCs which are found as environmental contaminants pose a risk to reproductive health.
Industries have retooled over BPA-Free products. If this new research proves to be true there will be countless ingredients (e.g. BPS) that will likely face the same type of scrutiny as BPA.
Reality Changing Observations:
Q1. Do you worry about the plastics you use at home for food, storage, etc.?
Q2. Do you believe that the government should further research the affects of BPA and other EDCs variants?
Q3. How can you educate your friends and family about the health affects of BPAs and other EDCs?
