BPA Found in Plastics Too Low to Be Harmful
A controversial component of plastic bottles and canned food linings that have helped make the world's food supply safer has come under attack: bisphenol A. Widely known as BPA, it has the potential to mimic the sex hormone estrogen if blood and tissue levels are high enough. Now, exposure studies show that in the general population, people's exposure may be many times too low for BPA to effectively mimic estrogen in the human body. [ Full Story ]
