(PRNewsFoto/Thermos L.L.C., Jason Wise) (User Submitted) – A new study from toxicologist Scott Belcher of the University of Cincinnati College of Medicine indicates that switching to metal water bottles from polycarbonate-plastic may not eliminate the risk of BPA leaching, reports Science News. It's the resin liner in the metal bottles that can be the culprit. Fortunately, the new BPA-free plastic bottles and those made from stainless steel with no liner or a BPA-free liner were found to have no traces of the pollutant chemical. BPA is an estrogen-mimicking pollutant that has been shown to trigger potentially life-threatening heart arrhythmias in rodents, and has been linked to a slew of potential health problems in humans.
