Plastics Today

It’s been a long road for the chemical bisphenol A (BPA) used in certain plastics. Scientists from all quarters—academia, the FDA and the plastics industry—have spent more than two decades studying BPA, and just when you think the definitive word on that chemical found in polycarbonate and epoxy resins has been delivered . . . it hasn’t. Remember what I said a couple of weeks ago in my blog, “The science is never settled?"

Government scientists have presented new evidence that the plastic additive BPA isn't a health threat.
Low doses of the chemical given to hundreds of rats, "did not elicit clear, biologically plausible adverse effects," said K. Barry Delclos, a research pharmacologist at the Food and Drug Administration's National Center for Toxicological Research.

For years it would not have been possible to use the word “silence” in the same sentence with BPA (bisphenol A).  The safety of BPA has been a long-running, robust controversy, in particular regarding concerns that BPA might cause health effects at exposure levels in the very low range that we as consumers might experience every day.

Over the past 8 years, senior scientists with FDA’s National Center for Toxicological Research (NCTR) designed and conducted a study of bisphenol A (BPA), the key raw material used to make polycarbonate plastic and epoxy resins. Named the CLARITY Core Study, this multi-year, multi-million dollar scientific study on BPA safety is of unprecedented scope and magnitude.  The results of the study were recently released and have now been peer reviewed by independent experts.
Learn more about this study and the extensive scientific database that supports the safety of BPA.  You’ll also learn about the latest regulatory information from the U.S. Food and Drug Administration and other government agencies.

No doubt you’ve heard about bisphenol A (BPA), the key raw material used to make polycarbonate plastic and epoxy resins. BPA has been mentioned in media reports for years and you may have had questions from your customers or colleagues wondering if materials made with BPA are safe. You may have even considered alternatives, just to avoid the BPA controversy. Before going any further down that path, it’s time to step back and consider what we now know about the safety of BPA.

We are constantly being asked to decide which side to believe in roiling controversies about health and the environment, which attract enormous public interest but often yield little in the way of resolution. Recent/current examples include: BPA, the herbicide glyphosate, GMOs, coffee, alcohol, e-cigarettes, and what constitutes a healthy diet… As an example of how to decide what to believe on a contentious question, Gawande took the case of BPA and used the discussion of the chemical in my book Getting Risk Right.
