Experts Discuss Bisphenol A

Forum Introduction

		The chemical bisphenol A (BPA) is used to make many plastic products used in American homes, including baby bottles. Recently, two expert panels examined whether BPA is likely to have adverse effects on human health. Two scientsts answered your questions on BPA.

Is there an online source to determine which plastics contain BPA?

Does my filtered water pitcher contain BPA?

What is my likely exposure level to BPA? What level is dangerous?

How does BPA get from a plastic water bottle into the water?

Do softer plastic bottles contain BPA?

Does BPA pose a risk to me as an adult?

Should I have my baby tested for exposure to BPA?

How may patients be exposed to BPA through dental sealants?

Does heat affect the release of BPA?


	Lisa of Exton, Pa., asks

	I'd like to know how BPA poses a health risk if it is in the plastic. For instance, if I have a water bottle that was manufactured with BPA, how does the BPA get into the water?

Retha Newbold responds:

BPA leaches out of plastics especially if the plastic is heated (for example in the microwave), if it is old and scratched or if it is washed with harsh detergents. BPA is reported to leach out of plastic water bottles even with normal use.

Earl Gray responds:

Earl Gray did not specifically address this question.
