BPA, which has been shown to disrupt estrogen levels in animals, is commonly used to make shatterproof plastics and polycarbonates. It is regularly used to create the lining in aluminum cans used for soft drinks and canned vegetables, as well as some drinkware liners.
The study suggested that BPA-free plastic bottles, and stainless steel bottles that do not have a liner, do not release any BPA and are safe to use. "The results from this study demonstrate that when used according to manufacturers' recommendations, reusable water bottles constructed from 'BPA-free' alternative materials are suitable for consumption of beverages free of BPA contamination," the study concluded.
