"Are people exposed to doses of bisphenol A in their canned foods and other consumer products that can harm them? Or are the amounts too low to cause any harm? This is the crux of a vehement debate that is being waged as federal officials are trying to decide whether the chemical, known as BPA, should be regulated."
"A group of toxicologists, including some who work for federal agencies, is questioning the likelihood that BPA is harming human health. But biologists studying the chemical’s health effects disagree, saying that what’s been detected in people is comparable to amounts that have harmed lab animals. BPA is arguably the most controversial chemical in consumer products. It is used to make polycarbonate plastic as well as food and beverage can liners and some paper receipts and dental sealants. What is widely agreed upon is that exposure is nearly ubiquitous. More than 90 percent of Americans tested have traces of BPA in their bodies."
