Why or why not? Bisphenol A (BPA) is a chemical that most Americans have been exposed to. Read an excerpt about BPA from theNational Institute of Environmental Sciences below.Bisphenol A (BPA)Bisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production ofpolycarbonate plastics and epoxy resins.. Polycarbonate plastics have many applications including use insome food and drink packaging, e.g., water and infant bottles, compact discs, impact-resistant safetyequipment, and medical devices. Epoxy resins are used as lacquers to coat metal products such as food cans,bottle tops, and water supply pipes. Some dental sealants and composites may also contribute to BPAexposure..The primary source of exposure to BPA for most people is through the diet. While air, dust, and water areother possible sources of exposure, BPA in food and beverages accounts for the majority of daily humanexposure.Bisphenol A can leach into food from the protective internal epoxy resin coatings of canned foods and fromconsumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles.The degree to which BPA leaches from polycarbonate bottles into liquid may depend more on the temperatureof the liquid or bottle, than the age of the container. BPA can also be found in breast milk...One reason people may be concerned about BPA is because human exposure to BPA is widespread. The 2003-2004 National Health and Nutrition Examination Survey (NHANES III) conducted by the Centers for DiseaseControl and Prevention (CDC) found detectable levels of BPA in 93% of 2517 urine samples from people sixyears and older. The CDC NHANES data are considered representative of exposures in the United States.Another reason for concern, especially for parents, may be because some animal studies report effects infetuses and newborns exposed to BPA.
