The bad reputation recently earned by BPA or bisphenol A, a chemical constituent of polycarbonate resin plastics, is probably well-deserved because it is an estrogen hormone mimic linked in hundreds of studies to potentially adverse health effects in mammals ranging from cancers and infertility to diabetes and obesity.
Fetal and juvenile mammals are particularly sensitive to exposure to low doses of estrogen mimics, raising particular concerns about BPA-containing plastics that infants and toddlers might encounter. Consequently, some manufacturers of baby bottles, water bottles and other plastic products are now marketing items as “BPA-free.”
Unfortunately, a “BPA-free” label offers no assurance that a product won’t leach chemicals with estrogenic activity (EA), according to a study appearing in the online March 2 issue of Environmental Health Perspectives. In fact, the study measured EA leaching from all sorts of food-contact plastic products made with resins other than polycarbonate.
