Bisphenol A is used primarily to make plastics, and products containing bisphenol A-based plastics have been in commerce use since 1957. At least 8 billion pounds of BPA are used by manufacturers yearly.[13] It is a key monomer in production of epoxy resins and in the most common form of polycarbonate plastic
"In general, plastics that are marked with recycle codes 1, 2, 4, 5, and 6 are very unlikely to contain BPA. Some, but not all, plastics that are marked with recycle codes 3 or 7 may be made with BPA."
 
The first large study of health effects on humans associated with bisphenol A exposure was published in September 2008 by Iain Lang and colleagues in the Journal of the American Medical Association. The cross-sectional study of almost 1,500 people assessed exposure to bisphenol A by looking at levels of the chemical in urine. The authors found that higher bisphenol A levels were significantly associated with heart disease, diabetes, and abnormally high levels of certain liver enzymes
A panel convened by the U.S. National Institutes of Health in 2007 determined that there was "some concern" about BPA's effects on fetal and infant brain development and behavior.A 2008 review has concluded that obesity may be increased as a function of BPA exposure, which "...merits concern among scientists and public health officials."A 2009 review of available studies has concluded that "perinatal BPA exposure acts to exert persistent effects on body weight and adiposity. A 2007 review has concluded that bisphenol-A has been shown to bind to thyroid hormone receptor and perhaps have selective effects on its functions.A 2010 review at Tufts University Medical School concluded that Bisphenol A may increase cancer risk. A 2009 study has found that newborn rats exposed to a low-dose of BPA (10 µg/kg) increased prostate cancer susceptibility when adults.In vitro studies have suggested that BPA can promote the growth of neuroblastoma cells
 
OK. Let’s try to avoid plastics......but did you know that BISPHENOL A is also present in almost every country’s paper money!
Please wash hands after handling money!
