    Bisphenol A: Should You Be Concerned?
    (2008-04-08) Tweet, Marysia Susan
    Bisphenol A (BPA) is a raw material primarily used as a monomer in polycarbonate and epoxy resin production. Industry produces more than 6 billion pounds of BPA each year, and it has been used commercially for ~50 years. Polycarbonates are used in infant bottles, plastic dinnerware and storageware, and therefore BPA may leach into human food. According to the Centers for Disease Control and Prevention (CDC), about 95% of Americans contain BPA in their blood. Recent concerns regard the effects of low exposure of BPA on human development and reproduction stemming from experimental evidence that BPA may weakly bind to estrogen receptors. The US NTP held an expert panel Aug 2007 reviewing 500 studies about BPA. The panel expressed “some” concerns that exposure causes neural and behavioral effects in infants and children and “minimal” concerns that it causes early puberty. No major health risks were found. A final statement is pending. The absolute decision regarding the effects of BPA on humans remains debated and is subject for continued studies.
