      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

Nalgene Danger

Recommended Posts

I tried testing Nalgene water for Bisphenol A by LC/MS, but it was below the detectable limit. I figure, I'd have to extract into organic solvent and concentrate to get measurable quantities.

 

Anyway, for what it's worth. Phenolic compounds are more soluble in alkaline solution and less soluble in acidic solution. The "harsh detergent" mentioned in the article is probably very basic (alkaline). The sports drinks most people use are rather acidic, owing to citric acid, etc.

 

The upshot is that if you put your bottle away with water in it, dump it out and refill with fresh before you go out.

You've more to fear from the electron ray gun you are sitting in front of or the myriad other chemicals you are subjected to. Or the source of the water in your nalgene.

I wouldn't be too quick to dismiss this risk, just yet. I think more work needs to be done.

 

The HDPE are supposed to be safe. REI sells them. But do they affect the taste the water like polypropylene?

Yes, they do affect the taste more but I wouldn't characterize it as a strong or unpleasent taste. I have used those bottles before and never had a problem with that. The question is how long it will take before a study shows those are just as cancerous for you. cantfocus.gif

no offense to anyone, but why shell out 8-10 dollars for a clunky water bottle that doesnt pack down, spills all over you when you drink, and now is unhealthy for you? but i guess it is a good way to show off all those rad stickers you got grin.gif i feel these fall into the same catagory as titanium backpacking chop-sticks

So aren't the chemicals that leach out of Nalgene's, also estrogen mimics? Maybe this explains RuMR's manboobs!

Somehow I feel vindicated for sticking with my old widemouth poly-something bottles which haven't killed me yet even if they were supposed to. On the other hand maybe I should play it safe & stick to bottled beer.

I have heard this concern over the past three to four years from customers looking for nalgene substitutes. I did notice in your link....that they mention it occured at room temp. This is new news to me. I have always heard that heat was the catalyst in the leaching process. Don't wash bottle in dishwasher! I'm no chemist, but if you taste plastic from your bottle...aren't you eating plastic? The Poly bottles taste horrible. There is no taste from lexan....are you eating plastic then? You can get a Sigg aluminum bottle that is coated on the inside to protect from the issues of consuming aluminium. The Sigg bottles cost around 16.00 to 20.00 dollars!! Nalgene bottle are around 6.00 to 9.00 dollars. Soaps and detergents are basic in PH. Any sports drink would be acidic on the PH scale. If you are just drinking water and don't leave your bottle all closed up in your pack for a month to taste like mold.....and actually air dry them out when you get back from a trip I have my doubts about the leaching issue. Is this a bigger concern than the air we breathe downtown?

If you taste plastic, you are likely tasting small molecules that if reacted further would be plastic. You also may be tasting plasticizers or other additives as was the case with the PVC toy concerns in the 70s. Bisphenol A is not plastic, it is a molecule that is reacted to form plastic.

A few links:

 

The "OH MY GOD Bisphenol-A WILL KILL US ALL" side

 

The "everything is fine. We care about your health and would never do anything to harm you becuase we love you, dear consumer. Now go watch some TV" side

 

Here is my take home message:

Don't worry about this one bisphenol-A thing. Yes, it is probably bad for you, but you can make other changes in your life that will have a much bigger positive impact on your health than not drinking from a nalgene. Namely: stop smoking. Drink in moderation. Avoid prepacked, "enriched", and highly-processed foods. Eat organic, whole, fresh, and varied food as much as availability and your budget allow. Drink lots of water (preferably from a glass vessel). Get lots of exercise. Spend more time in clean environments (clean air and water) such as the North Cascades. Spend less time spraying on cc.com.

My answer to this has been to use stainless steel when practical. Klean Kanteen (see www.kleankanteen.com) has a 22 oz. bottle that is rugged and relatively light. Sigg has a small 12 oz. mug that I really like for cold and hot drinks ( see http://www.gear-zone.co.uk/eshop/Sigg-Metro-Mug.html ). It travels well and is also rugged and relatively light.

 

Otherwise, it's a pretty tough battle. I mean what isn't packaged in plastic these daze?

Under "Who We Are" on the Bisphenol A web page:

 

"This web site is sponsored by the Bisphenol A Global Industry Group of the American Plastics Council; the Association of Plastics Manufacturers in Europe; and the Japan Chemical Industry Association."

 

The site would probably be equally useful (and truthful) if it re-routed all links on the page back to that sentence.

Without reading any of the links, I think this one has already been around the block a few years ago. The (original) writer issued a retraction because tests were not done on food grade product.

 

The bigger issue might be the use of lexan for bottled mineral water. The material is of a lower quality (not meant to be re-used) and water may stay in such for months prior to consumption.
