Last week the New York Times and Washington Post published articles regarding concerns that are being raised in Canada and the United States about the possible dangers of Bisphenol-A (BPA) to humans.   BPA is a heavy plastic used in many common household goods, including baby bottles and liners in food cans.  The New York Times  published in article in its Health Section on Tuesday, April 22 that tries to respond to some of the concerns about the toxicity of BPA.   Along with addressing whereBPA is found and providing some epidemiology on the extent of human exposure, the article also offers some suggestions as to how to limit exposure.
