This chemical, Bisphenol A, has shown up on my radar recently, first through this article:
(sorry couldn't get the hotlink to work)
Basically, the debate is about whether this chemical, which leaches into water from PET bottles, is toxic or not. Independent scientists say yes. The plastics board and manufacturers say no. Part of the controversy seems to come from the fact that BPA acts like a wannabe hormone, and accordingly, it does more damage at low levels than at high levels (which have the opposite effect on hormone receptor sites).
By damage, the research suggests that BPA scrambles the cells in fetuses, causes breast and prostate cancer, as well as down syndrome etc. The doctors in the article were saying that they weren't waiting for a ban: they were removing all plastic from their homes and anticipating a legal battle akin to the "tobacco doesn't cause cancer" one.
This makes me nervous. Nalgene mentions BPA on its site and says it isn't dangerous. Platypus doesn't mention anything (I emailed them), but I am beginning to suspect that most plastics are made with BPA.
So two questions:
1) Have you heard of this / are you concerned?
2) If, in fact, BPA is a carcinogen, what are our options for carrying water into the bush?
