What is bisphenol A?
Bisphenol A is a chemical found in polycarbonate plastic and epoxy
resins.
Polycarbonate plastics are used in certain food and drink packaging
and also in compact discs,
computers, impact-resistant safety equipment (such as helmets and goggles), and
medical devices.
Polycarbonate plastics that contain bisphenol A usually have a No. 7 on the
bottom, within the "chasing arrows" used to sort plastics for
recycling, according to the National Institute on Environmental Health (NIEHS).
But the American Chemistry Council, an industry group, strongly advises against
using those recycling codes for any purpose other than sorting your recycling,
since the numbers aren't about bisphenol A or other plastic chemicals.
Epoxy resins line metal products such as canned foods, bottle tops, and
water supply pipes.
Is bisphenol A safe?
In a draft report, government scientists note "some concern" about
bisphenol A's possible effects, based on lab tests in rodents. But that report
isn't final, and the scientists aren't calling bisphenol A unsafe.
