If BPA sounds familiar, it’s probably from seeing “BPA Free” printed on your plastic water bottles. BPA stands for the chemical bisphenol-A which has been determined to be harmful to the development of fetuses and infants. The BPA free campaign began with the findings of a research project by Dr. Frederick vom Saal which showed that there were dangerously high levels of BPA in people’s blood from ambient exposure. However, leading scientists and journals in the field of Toxicology have found this conclusion flawed and have shown that levels of BPA are barely detectable by even the most advanced equipment. Vom Saal has attacked all studies with conflicting results as disingenuous. The media has perceived this as uncertainty within the toxicological community over the danger of BPA. There IS in fact agreement. The current consensus is that while BPA still poses a threat, exposure is not high enough to raise concern. So go ahead and drink from those old Nalgenes and throw away those clanging new metal cantenes. And make friends with a scientist, the media often doesn’t fully understand the implications of science.
