Polycarbonate Plastics and Human BPA Exposure

Drinking from plastic bottles containing BPA poses health risks. Environmental Health Perspectives vol 117 issue 9 reports the following:

"Urinary Levels Rise with Use of Drinking Bottles

Public and scientific concerns about exposure to bisphenol A (BPA) have risen in the last few years, with Canada and some U.S. states and cities banning BPA from polycarbonate baby bottles and other products sold for use by infants and children. Despite these concerns, little is known about whether the use of polycarbonate food or beverage containers actually contributes to BPA body burden in people. A new study of human exposure to BPA from drinking containers now shows that study participants’ urinary concentrations of the molecule increased by two-thirds after they used polycarbonate drinking bottles for 1 week [EHP 117:1368–1372; Carwile et al.]."

We have already switched to aluminum.
