Canada’s health department is expected to become the first regulatory body ever to declare chemical bisphenol A a toxic substance that humans should reduce their exposure to. BPA shows up in (and leaches from) hard plastic water bottles, aluminum cans, and other containers that consumers regularly eat and drink from. The chemical, which has been linked to reproductive anomalies, has come under some scrutiny in the United States, but industry folks insist that it poses no threat. A declaration by Health Canada that BPA is toxic would set the stage for federal regulation or a ban.
