 True. I think that we're preaching from different ends of the same page. I'm also of the mind that if something has a tiny risk associated with it, if removing the risk is effortless, why bother taking the risk?
For me the effort to replace all my plastic bottles and tubbery is too much of an effort but I will certainly be happy to buy BPA free products in the future.
Have you read Deep Survival by Laurence Gonzales? It's very much about these kind of risks (real, imagined, proven or otherwise).

 Wasn't the discovery of bad BPA (like theres a good sort) a godsend for the the likes of nalgene ? People like me do not throw away usable gear for no reason .I still have a500ml bottle and use it ,and yet i bought it in 1987 .Sadly for them i do not buy into bottles give you cancer thing . and furthermore i found the new lexan bottles i bought from aldi (nice price) are just as good . It just seems that it's another case of new and improved marketing to sell new and improved goods .

 I think we should be more worried about the elevated dihydrogen monoxide levels found in these bottles during and just after use. http://en.wikipedia.org/wiki/Dihydrogen_monoxide

and realistically, we should be more worried about being killed in an RTA on the way to a walk or climb, since the chances are far higher.

Nick J. You are right. Having been hit by cars on several occasions (mostly by door mirrors) on bendy country roads, I will vouch for your idea above. I am still not sure as to how seriously take any threat from plastice bottles. Many of us are concerned over the toxins contained in a bottle we may only drink from one or two days per week, but are still happy to ingest toxins daily in the form of alcohol, or cigarettes. I am tee total, but when I go to the pub, even my draught coke comes via a poly tube, or in plastic lined cans! Foot note...Although having said that, I will now probably be hit by a truck full of nalgene bottles, and someone will then point out the damage caused by these innocent looking bottles

 > I do not follow research on lexan/nalgene, but do know used 'pop' bottles leach toxins after several uses (the clue is usually a number stamped on the base of the bottle (indicating the number of times it can be safely refilled)). Do you have any references for this information, Ray? I'm afraid I'm sceptical; I suspect that any numbers on the bottom of bottles are mould IDs, and not indicators of the number of times a bottle may be re-filled. Leeching of toxins is far more likely to be time and temperature related, rather than related to the number of refills. The shelf life of bottles water is measured in years.

 smart plastic? it knows how many times it's been used? time and temp as the capt suggest is more likely. but then they would only leech nasties well after the "best before" date wouldn't they. smart chemicals. only do something after a certain time.

Hi CP. No I don't have any references on this matter. Although your theory on mould ref's sounds right, I was taught this at college, in relation to health and safety, about one year ago. The information came from my tutor, and was presented as an inside tip from bottle manufacturers (it being something they did not wan't to become too widely known). I completely agree with your last paragraph, but guess it may be related to other factors too. Maybe it's a bit like the fact a swimming pool may be more likely to leak after it has been emptied and then refilled. I know that was not the best example ever in the history of the universe.

> I suspect that any numbers on the bottom of bottles are mould IDs Fairly easy to confirm: go to a supermarket and look at the numbers on the bottles of any brand of drink. If, within a particular product, they are different, then I'd suggest it's a mould number. If they're the same, it doesn't rule out that they are mould number (it would depend how bottles pass through the production to filling chain).

Hi CP. I'll leave it to you. I am currently away, camping (trying out a new Quechua 4.2 four berth), and don't fancy the idea of supermarkets right now! That said, I am still managing to visit chip shops, resteraunts, and cream tea parlours. It's a tough job but someone has to do it
