Which materials are sources of exposure to bisphenols?

• A. Glass containers
• B. Canned food lining
• C. Paper towels
• D. Natural fibers

Answer: (B)

Bisphenols, particularly bisphenol A (BPA), are synthetic compounds predominantly found in certain plastics and resins. They are often used in the production of materials that have direct contact with food and beverages. Canned food lining is a common source of bisphenol exposure because many canned goods are coated with a resin that contains BPA. This resin helps prevent the metal from corroding and leaching into the food, but it also means that BPA can migrate into the food products themselves. As people consume these canned goods, they can inadvertently ingest bisphenols, which raises concerns regarding their health effects. In contrast, glass containers do not typically contain bisphenols, as glass is an inert material that does not leach chemicals. Paper towels and natural fibers, while they have various uses, are not usually associated with bisphenols in terms of exposure. Thus, the correct answer points to the significant role that the linings of canned foods play in bisphenol exposure.
