For many years, scientists around the world have been intensely interested in bisphenol A (BPA), a common chemical used to make polycarbonate plastic and epoxy resins. But what have we learned from the supersized investment in research on this one chemical, and what can we expect in the future? Recent articles suggest that we haven’t learned as much as might be expected from such a large investment, but more research on BPA is probably in our future anyway. The intensity of interest in BPA is revealed by searching for studies on BPA in PubMed, a biomedical literature database operated by the U.S. National Institutes of Health. Using the search term “Bisphenol A” on November 14, 2014, PubMed identified 8,675 citations! More than 80% of the citations were published after 1999 and there has been a steady increase in the number of new publications almost every year. More than 700 citations have been entered in 2014, with more than a month yet to go. Read more.
