Q. What is Bisphenol A (BPA)? (UPSC Prelims 2008)
Answer: A chemical used for the development of food-packaging materials
Notes: Bisphenol A (BPA) is an organic synthetic compound used primarily to produce polycarbonate plastics and epoxy resins, key materials in food and beverage packaging like cans, bottles, and containers to enhance durability and prevent leakage. It is one of the highest-volume chemicals produced worldwide, with over 6 million tons annually. BPA can leach into food, raising health concerns like endocrine disruption, prompting BPA-free alternatives. Options (a), (b), and (d) are incorrect as BPA is not a medical test, doping screen, or steel alloy.
