In order to reduce the # of plastic water bottles we were using I purchased a couple of large hard plastic bottles from Whole Foods.
In Friday's New York Times there was a big article on the health hazards of these bottles because of bisphenol A.
Any thoughts or comments??

Re: Bisphenol A
Tue, April 22, 2008 - 4:05 PMbisphenol A (and other classes of bisphenol) and all classes of phtalates have been linked to health hazards. The strongest evidence suggests interference with the reproductive system when these substances are ingested by toddlers and other such young, vulnerable humans. they are used to alter the consistency of pvc. imagine a substance capable of making hard plastic soft. then imagine your children teething on products containing those substances..
Pthalates are banned in California. We're still working on Bisphenol-A. Union of Concerned Scientist and pretty much every Enviro group in CA backs the ban.
The evidence is difficult to mount, due to moral limits on human expirementation. Most often though, a suspected substance ends up being proven harmful (see lead, every synthetic pesticide, agent orange, etc.). most common reasons for discrediting a study: 1)it wasn't performed on humans; 2) there are other factors outside of the lab that could be causing this. History bears out that humans outside the lab become the guinea pigs, and the results are rarely favorable (see lead, agent orange, all organochlorines, etc, etc, etc,).
at the risk of sounding cliche, i would say better safe than sorry on this one. and for a basic rule of thumb, don't ingest plastic.

Re: Bisphenol A
Tue, April 22, 2008 - 8:40 AMThere's a discussion about this in another tribe I'm in. The consensus is that there is, as yet, no consensus.
Some people say they're horribly dangerous and we're all gonna die. Some people say there's a danger but it's slight and not enough reason to change your habits.
I'm just really tired of all the "doomsaying" articles and alerts. I'm gonna keep doing what I'm doing until there appears to be more agreement about whether it's deadly or not. -

Tue, April 22, 2008 - 12:35 PMI don't really think its much heavier than a plastic water bottle. Most of the weight is from the water itself. -

Re: Bisphenol A
Tue, April 22, 2008 - 2:32 PMI really want to replace all of our Nalgene water bottles with stainless, and have wanted to even before this recent scare...but they are so expensive...I need two little ones for my kids, a quart for me, and at least three quarts for my husband, who is often working at job sights where he cannot refill all day...any info on a relatively inexpensive source for these would be so appreciated! Thanks, Aura -

Re: Bisphenol A
Tue, April 22, 2008 - 5:42 PMI didn't catch Friday's article, but from reading many of the past articles on this plastic bottle thing what makes no sense to me is how plastic has *suddenly* become harmful to drink/eat out of. We use plastic cups, plastic plates, plastic bowls, plastic utensils -- they get washed (non-disposable kind) and reused over and over. People have been doing this for DECADES. How the heck is using a plastic cup, washing it and reusing it any different that using a plastic bottle (like nalgene or tupperwear or whatever), washing it and reusing it?
The reports I've read have basically said that the detergent from washing a bottle breaks down the plastic through some kind of interaction, thereby causing some of the chemicals from the plastic to leach into the water. But the reports have also said that it takes *thousands* of washes for this to happen, and even then it's a minimal amount. So yes, if your bottle were to actually last 10 years and you managed not to lose it or break it in that time and you used it every day, after 10 years there might be a measurable (though minimal) amount of leaching that could be damaging.
I can't really see that scenario being cause for a dramatic decline in health country-wide. I mean, if this were a serious problem, wouldn't there be a huge number of people with health problems suddenly appearing in the past decade or two from continued use of plastic drinking containers? Part of me wonders if this is simply a convenient "study" to get us to abandon reusable bottles/glasses and BUY MORE single-use items. Coz you know, buying more "supports the economy". -

Re: Bisphenol A
Wed, April 23, 2008 - 12:01 PMI'm with you guys. What I can't stomach is people who gripe about plastic bottles, or human growth hormone, but yet they're smoking… May not be any on this tribe, but I've met them in real life.
Or my husband, while going through chemo and still smoking telling me I should get rid of the charcoal grill "if I care about him at all" because if you don't marinate your meat enough, there is a slight carcinogenic quality to the grilled food. I was like, really? You won't even put the cigarette down when you bring this up as a topic for discussion? -

Wed, April 23, 2008 - 1:59 PMDuckAmuck,
*L* I guess it is funny that some people will be concerned about plastic issues, but still smoke, drink , do drugs and pump themselves full of 10 cups of coffee. ;)
I don't mind someone bringing up the topic or feeling the need to switch from plastic, I'm just honestly baffled about the issue. I haven't seen any articles that explain the questions I raised. And I don't really trust the gov or the media to lay it straight -- sometimes they hide or hype info for another agenda, making it very hard to wade through info. -

Bisphenol-A has a posse
Wed, April 23, 2008 - 3:17 PMThough Bisphenol-A may have a minor impact on adults, it may be extremely hazardous for youngsters. Also, it is only one of a plethora of confounding factors that, have, in my opinion contributed to a decline in health. It is one of the thousand cuts by which humans and our ecosystems are suffering and will die.
Ms. essentially parrots what defendants in toxicity cases have been saying for decades. Again, history bears out that the plaintiffs, though they may not win in a court of law or scientific laboratory, turn out to be right. Products like Bendectine, Vioxx, DDT get pulled; Settlements get paid out of court as can be seen with Agent Orange and Union Carbide's disaster in Bhopal India. Or, cancer clusters just keep being miraculously inexplicable, like at Love Canal, where Dioxin was leaked for years.
There is, in fact, a major decline in health (a steady increase in chronic disease) in the US and other industrialized nations. The causes are many but take decades to pinpoint, due to the conservative (as in careful) nature of science and law. Study the link between lead paint and learning disabilities in children for evidence. But you can be sure that bisphenol-A is one contributor to the heavy toxic burden of humans and other animals, and is especially hazardous to unborn and young children. If you widen the scope of time you're looking at, you will see an immergence of cancer in adults and developmental disabilities in children that correlate with the advent of synthetics and plastics
For all its wonders, the byproducts of the plastics age is wreaking havoc on our lazy bodies and the ecosystems that supply our healthy food. Petroluem to produce plastic. Pthalates and Bisphenol-A to maniupulate it's consistency. The new compounds created when effluents from plastics manufacturers unleash waste into our environment (one large class of these compounds, organochlorines, bond to fat cells and can only be filtered out through breasfeeding).
of course, this becomes a question of managing the risks you take. I would say one good rule of thumb for risk management is to avoid ingesting plastic.
Bisphenol-A may not be your biggest problem, but don't dismiss it just yet. And don't dismiss it's interactions with other substances you expose yourself to, or its effect on children.

Re: Bisphenol-A has a posse
Fri, April 25, 2008 - 12:47 PMGeorge,
actually I'm not parroting anything. that would imply I'm merely repeating others' opinions that I've read elsewhere. my previous posts are just my own assessment of the situation from the articles/reports I've seen. However, I would like to know more about this since, as I said, I haven't found anything that addresses my questions. All info has been very broad on the general subject of Bisphenol-A (for example, your posts just mention what it is) or the general subject of plastic use. You seem very knowledgeable on the subject. Perhaps you can point me to some links or resources that address the following?
risks in the different kinds of plastics, why reports are targeting nalgene bottles specifically when we use other plastics more frequently (such as bowls or cups), what plastics have been studied, tests on which plastics break down more easily than others and what specfically is breaking them down, the amount of harmful substances released per detergent and plastic, the amount that needs to be consistently consumed to cause problems, studies indicating that plastic is specifically the cause of particularly illnesses. -

Re: Bisphenol-A has a posse
Mon, April 28, 2008 - 4:40 PMmy apologies for poor word choice regarding "parroting." that was not well thought out.
also, i'm not looking at media reports either, cause if we took all our cues from the nytimes and sf chronicle, we'd all be duped into supporting wars against phantom agressors in the middle east.
at the end of this post is some info i found for published studies on bisphenol-a. Though, i'm not too internet savvy, so i don't know if you'll actually be able to read the studies. somewhere in the Bisphenol-A Free Portal I found a quote by an FDA official who admitted that with the lack of hard proof, but a respectable suspicion, it is advisable for not put this stuff in your kids' mouths.
what I was trying to point out in my post, however, is that the attempt to manage the risks we take based on assessments of individual substances frames the issue in a way that serves us no good whatsoever. In fact, that framework has been used by polluting industry for decades to avoid responsibility for their actions. What i am asking you to consider is that, historically, when suspicion is aroused, similar to what we know see around bisphenol-a, those who profit from it ask the same questions you ask, then deny the results of any studies that give an answer they don't like. Then they pay scientists to manufacture dubious studies to the contrary. (Then eventually they cave in under the weight of the real studies and the real illnesses that can no longer be dismissed. Then they replace the substance with some alternative, which turns out also to be harmful, because it's a synthetic made from nasty things and we only banned its sister because the framework says we have to prove each individual substance harmful and those findings don't necessarily apply to other substances which are identical in very important ways, but technically different. Then we spend another lifetime trying to convince everyone that bisphenol-b is harmful. etc.)
All the examples i site in my previous post fall into this pattern. Pthalates (bisphenol-a's cousin) follows this pattern, and is now banned in the EU and California. Bisphenol-a is following this pattern and is banned in Canada, San Francisco, and soon to follow elsewhere.
Essentially, all synthetics are highly suspect due the laws of chemistry. Our society has decided to deem them innocent until proven guilty, with disastrous results. Read Pandora's Poison by Joe Thornton for evidence that the plastics industry is softly killing our bodies and ravishing ecosystems (which will necessarily destroy life in general, and us eventually). No, not just Nalgenes, everything.
I'm saying it is time for us to regard them with suspicion, because they've earned it. And when there's as much suspicion as with bisphenol-a, don't you think it's wise to be cautious?
That's the Precautionary Principle i'm invoking. A Wingspan Conference was held on it years ago, but I can't find info online. I have the book somewhere but I can't remember the name of it. It might be called "The Precautionary Principle." But it looks like there's some info on the Precautionary Principle online.
1)Flaws in industry research-According to vom Saal and Welshon's analysis in this paper, of the 130 studies of low dose effects of BPA published as of summer 2005, 119 have been funded by governments and 11 by industry. 92% of the government funded studies report adverse effects. None of the industry studies do. In this paper, vom Saal and Welshons examine in detail the government and industry funded studies that found no effects, and show several reasons why poor study design destined them to failure.
