Dangers of Nalgene water bottles and other plastic sport water bottles

Many Nalgene water bottles and other hard plastic sport water bottles are made of polycarbonate (#7 on the bottom) , which may leach Bisphenol A, an estrogen-like chemical. Canada is considering a ban of products containing Bisphenol A (BPA) and a new American study links it to breast cancer and early puberty, and is particularly concerned about the effect on babies. Others have raised concerns about the effect of feminizing hormones on men, such as breast enlargement or dropping semen counts. At the same time, sport water bottles are ubiquitous and we don't want people going back to buying bottled water. What should you do? Time to nix the Nalgene? We looked at our past posts and the latest reports, and suggest the following.
7 Ways to beat BPA, in order of Importance:
1. Ditch the clear plastic baby bottles, right now. All the research that says there are problems point at the effect of the estrogen-like BPA on children as being the most significant. 2. Tin cans are often lined in plastic BPA and sit around a long time; get rid of older tin cans, particularly if they contain tomatoes and other acidic fruits. 3. Don't use your polycarbonate bottle for hot drinks. 4. Polycarbonate bottles get crazed and cracked as they get older; that increases surface area. Get rid of old ones.5. Replace your Polycarbonate bottle with a Sigg, Kleen Kanteen, or the new BPA free Camelbak, particularly if pregnant or pre-pubescent.6. Replace jugs where water sits around a long time, like Brita knockoffs. (Brita says they are BPA free) 7. Stop using jugged water cooler water, get a filter and cooler that uses city water. It is a big jug so there probably isn't much of a problem, but why are you drinking bottled water anyways?
Don't worry about polycarbonates in non-food related products like CDs and DVDs. but keep them out of babies' mouths.
