Explanation

Bisphenol A (BPA) is an industrial chemical that has been used to make certain plastics and resins since the 1950s. It is a key structural component, or monomer, primarily in the production of polycarbonate plastics and epoxy resins. Polycarbonate plastics are hard, clear plastics often used in products like reusable water bottles, food storage containers, baby bottles, compact discs (CDs, DVDs), and some eyewear. Epoxy resins are used to coat the inside of food and beverage cans and in water pipes. Due to concerns about potential health effects, the use of BPA has been restricted in some applications, particularly in products for infants.
