Experts Discuss Bisphenol A

Forum Introduction
Baby bottle: Photo credit FDA 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.
QUESTIONS
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?
Lori Kelly of New Canaan, Conn., asks
Do the softer plastic bottles (i.e. Poland Spring water, Vitamin water) contain BPA? We drink a lot of them.

Retha Newbold responds:

Most polycarbonate plastics (#7 recyclable) contain BPA but it is also found in other kinds of plastics. It is best to contact the manufacturer and ask about their specific product.

Earl Gray responds:
Earl Gray responds:

Many of the questions indicate that people are already very concerned about using products with BPA in them and already have stopped using these products. They want to know what levels are safe. I expect the scientific community will resolve this issue completely in a few years if the correct studies are done. Certainly if one is truly concerned about using this or any other product because of the potential chemical exposures they should not use them, if for no other reason than to eliminate stress.

Folks should also be aware that every official group that has looked at the risk of BPA to humans in Europe and other countries has not endorsed the low-dose studies and, for this reason, none of these products are regulated anywhere since the available science does not support such regulation.
