Is there an online source to determine which plastics contain BPA? Does the recycle triangle number indicate detail on composition?
Retha Newbold responds:
There is currently no way to tell which plastics contain BPA or what levels are present in products but data suggests that its use in consumer products is increasing yearly. The recycle triangle doesn't address BPA content however #7 category, which is mainly polycarbonate plastics used in baby bottles, water bottles, "sport" water bottles, metal food can liners, "sippy" cups and some clear plastic cutlery all have been reported to contain measureable levels of BPA. Still there is no way to tell about other plastics.
Earl Gray responds:
There are many, many sources of information about BPA in plastics on the Web. Some are from NGOs and others are industry Web sites. I would suggest that one just search on google or some other search engine for "BPA plastics" and read a variety of these from both sides of the issue to get a balanced idea of the controversy about this chemical and its purported toxicity.
