Vancouver-based Mountain Equipment Co-op is waiting for Canadian health regulators to finish a preliminary review before it reconsiders restocking its 11 stores with the reusable, transparent bottles made with bisphenol A, or BPA, a compound created by a Russian chemist in 1891.
There is little dispute that the chemical can disrupt the hormonal system, but scientists differ markedly on whether very low doses found in food and beverage containers can be harmful. The U.S. Food and Drug Administration sides with the plastics industry that BPA-based products do not pose a health risk.
