Yay, my first post on our new Life Without Plastic blog! What fun! I'm Chantal's partner, Jay, the other founder of Life Without Plastic.
Unfortunately, I have some bad news - not a rare thing in the world of plastics. Some recent articles in the peer-reviewed journal Environmental Health Perspectives (EHP) highlight new research indicating more problems with bisphenol A (BPA), the estrogen-mimicking synthetic chemical used to make polycarbonate plastic and the plastic linings of most food and beverage cans. BPA has been linked to various health problems including cancers, obesity, attention deficit hyperactivity disorder and alteration of hormonal, developmental and reproductive functions -- often at extremely low levels of the chemical.
An article in the November 2008 issue of the journal indicates that BPA may build up to a level 11 times greater in newborns than adults because babies lack a key liver enzyme required to break the chemical down. For this reason, one of the researchers recommends parents try to avoid exposing their infants to BPA and that pregnant women miminize their BPA ingestion to protect the fetus. Read an overview of the article in today's Globe & Mail. And here is the actual article in EHP.
As well, the February 2009 issue of EHP features an article showing how BPA blocks the effects of certain breast cancer chemotherapy drugs. This research is especially relevant as it gives some idea of how BPA may affect established breast cancer and its treatment in humans - in much of the previous research, animal studies have shown how BPA increases susceptibility to certain cancers. The authors conclude that these data provide considerable support for the accumulating evidence that BPA is hazardous to human health. I think we can now take that as a given. Check out the EHP site for an overview of the article and the actual article.
I'll try to find some happier news for my next post.
