BPA Leaches From Polycarbonate Bottles Into Humans

kdawson posted more than 5 years ago | from the glass-makes-a-comeback dept.

Medicine 251

Linus the Turbonerd sends in the bulletin that BPA, a toxic chemical used in the production of polycarbonate, the plastic composing hard, clear water bottles, has been found to leach out of such containers, directly into the water that their users consume. "In addition to polycarbonate bottles, which are refillable and a popular container among students, campers and others and are also used as baby bottles, BPA is also found in dentistry composites and sealants and in the lining of aluminum food and beverage cans. ... 'We found that drinking cold liquids from polycarbonate bottles for just one week increased urinary BPA levels by more than two-thirds. If you heat those bottles, as is the case with baby bottles, we would expect the levels to be considerably higher. This would be of concern since infants may be particularly susceptible to BPA's endocrine-disrupting potential,' said Karin B. Michels, associate professor of epidemiology at HSPH and Harvard Medical School and senior author of the study."

Isn't this extremely old news? Companies have been making BPA-free plastic bottles now for a long long time, including baby bottles.

Philip K Dickhead (906971) | more than 5 years ago | (#28077107)

This is a new study, just published. It confirms earlier indications that BPA's are far from inert and it adds data to specific scenarios whereby they are transmitted for ingestion.

Many manufacturers have dropped BPA for reasons of public-relations.

Replaced by?

Other unproven, untested and highly suspect additives for 'softening' and 'pliability'.

It's still extremely old news. This study merely confirmed what people have known for years. If they hadn't, they wouldn't have dropped BPA-containing plastics from their product lines.

It should be noted that the more flexible plastics often used in water bottles, such as HDPE and PET or PETE, do not contain BPA.

Anyway, anyone who can't read between the lines of Nalgene stopping their use of a material they've been claiming is the best thing ever isn't very smart, and deserves toxics in their pee.

The most hilarious part is that if you told people ten years ago that polycarbonates were dangerous they'd say that you were a big fucking idiot. Five years ago you'd be a conspiracy theorist. Today, you're vindicated. Tomorrow, you'll tell them about something else that's probably dangerous, and you'll be a big idiot to them again.

Ten years ago, if you'd said that, you *would* have been an idiot. Even idiots can be right once in a while, in the same way that a stopped clock is correct twice a day.

If, instead, your claim was simply that the bottles weren't proven not to leach anything, you'd be vindicated, and all the idiots who bitched that "you can't prove a negative" would still be idiots.

I'm in the same boat as your parent comment, I only drink from glass or aluminum containers (not cans, more like the containers for bikes). I don't know why it should be ridiculed. I don't even trust the claims anymore - expensive and "unbreakable" polycarbonate drink glasses from Target broke in the dishwasher within weeks. Cost 4x more than the normal glass.

I'm not a chemistry expert, but to me glass has always been a simple, very inert substance which is easy to clean, with little to go wrong as long as you're not drinking from lead crystal. Unlike most plastic, glass doesn't really fade in the dishwasher or scratch using steel wool, and nothing happens when you put in the microwave for a long time. That basic inertness is apparent to everybody.

Plastics, otoh, are extremely varied already in the basic consumer space, there are still new things to learn from it all the time (obviously, as this study shows) and is just more complicated a topic.

I miss the days when soda came in a glass bottle...

Not anywhere near quickly enough, considering that the vast majority of polycarbonates still contain BPA. As long as the cost saving of BPA exceeds the sales lost, companies won't move a bit. Parents with young children tend to be hyper-vigilant, so sure, companies will remove BPA from baby bottles. But people don't pay as much attention to other products.

Re:Bulletin? Bulletin? (2, Interesting)

nametaken (610866) | more than 5 years ago | (#28078295)

From Nalgene... I've bolded the part I found interesting.

Question: Why is Nalgene transitioning from polycarbonate to other materials?
Answer: [Blah, blah, blah] Our decision to phase out production of the Outdoor line of polycarbonate containers is in response to consumer demand for products that do not include Bisphenol-A (BPA).

We are confident that the bottles which contain BPA are safe for their intended use. However, because of consumer requests for alternative materials, we have decided to transition our polycarbonate product line to Eastman Tritanâ copolyester. This product joins our family of bottles and containers made of various non-BPA materials such as HDPE, PP, LDPE and PET.

[Blah, blah, blah]

Based on the findings of the Food and Drug Administration, The Environmental Protection Agency, The European Food Safety Authority, The German Federal Institute for Risk Assessment, The Japan Ministry of Health, Labor & Welfare, The American Plastics Council and other reliable sources from around the world, we continue to firmly believe in the safety of our products containing BPA. However, we intend to carefully monitor the results of the National Toxicology Report and the Canadian government's inquiry into this issue and any other relevant scientific information.

Now I'm not sure the Plastics Council is a group I'd want to get my info from, but the rest sound somewhat compelling. So what's the deal, yes it leaches, but it's not necessarily harmful? I wouldn't want to be a sucker for some company's BS, but what's the deal with groups above?

genistein is a potent estrogen mimic

Effects in males

Isoflavones can act like estrogen, stimulating development and maintenance of female characteristics or they can block cells from using cousins of estrogen. In vitro studies have proven genistein to induce apoptosis of testicular cells at certain levels, thus raising concerns about effects it could have on male fertility.[10]

soy has been used in many cultures for thousands of years

Great! I think we should all go back to lead plumbing and lead pewter cups.... After a couple of generations, we won't have all these fancy "scientific" reports.... Instead we will have... "wite paint tastyer than blu paint"

VitaMix downplayed, Rubbermaid came clean (1)

scorilo (654174) | more than 5 years ago | (#28077453)

Vita-Mix.com, who have been making high-performance mixers with polycarbonate containers forever, deny any such adverse effects and encourage their customers to "mix" as long as it takes to make hot soups (that is, starting with a cold mixture, keep mixing until the liquid is hot). Rubbermaid, OTOH, has had on their website an interview with a Johns Hopkins University scientist who states that heated or boiling liquids will accelerate BPA extraction (quite obvious, if you think about it).

FUD? Doesn't seem to harm infants... (4, Interesting)

Anonymous Coward | more than 5 years ago | (#28077463)

There was an interesting article on NPR recently where they looked at premature infants who were on heart-lung machines whose tubing all used such BPA. These kids had much higher levels than other kids in their systems. 15 years later there were no detectable problem with their reproductive systems. Granted the study size was small, but there is clearly no dramatic effect from significantly larger levels than adults get from using water bottles.

What is most disturbing about this is that in this "highly technical" (ahem) community, only one poster noticed that what is important is not whether or not BPA is present in the urine or blood of people who use the bottles, but rather it is what are the health effects if any when it is present? A related question still unasked here is, how far away does a 69% increase in BPA levels put us from FDA-posited unsafe levels? Since the normal level in the population is thousands of times less than the unsafe level, this is an important piece of data that was missing from TFA.

That the people most at risk (infants) happen to use them in the worst possible way (heated). Now it will be interesting (and scary) to see some studies on the long term effects of the exposure to the population. No wonder this generation will die younger than their parents!

There's no need to warm infant formula.

Maybe so, but parents do it anyway for comfort of the child.

first and foremost, you can suck it, FDA! suck it hard!

You knew this all along and you put us all in danger due to corporate influences.

We should now be able to see the FDA chief, who allowed BPA to continue in products, put in jail for gross negligence.

The linked report was less than useful, since the reporting was done in relative terms - e.g. "increased by two thirds". Okay, but two thirds over what? There are generally specific concentrations above which a chemical is identified as harmful by the government (or by a watchdog agency, if you don't trust the government). Why not say "BPA levels increase from the background level of xxxxxxx to a ppm/ppb of yyyyyy in individuals who drank from these bottles for one week"?

So really, even if the shift away from BPA plastics wasn't already well on, there's no indication from this report whether I should actually be concerned or not. And frankly, as someone with a science background, this sort of thing makes me LESS likely to be concerned. When I see fuzzy reporting, my first though is it was done intentionally because they can't support their case using objective numbers. I've seen this happen in honest-to-goodness scientific papers way too often to not notice.

It makes me skeptical as well, but I think there are at least two other reasons things get reported this way:

  • Reporters are afraid that if they mention more than one number, Joe Sixpack's eyes will glaze over and he'll think some gawl-durn science geek is trying to talk down to him, and he's less likely to read news from this source again.
  • The reporters themselves have such a poor grasp of science and math that they don't know that anything matters other than the relative increase.

I wondered about that too. I also noticed that it specifically mentioned urine concentrations. Now, I'm far from an expert on the subject, but as I understand it this means that my kidneys are doing their job, and filtering the stuff out of my blood stream. It seems to me that how much of this shows up in my urine is less interesting than how long it sits in my body before my kidneys take care of it, and what problems it's causing there.

That small amounts of BPA are capable of leaching out of bottles and into the liquids that they contain has been known for years. What's less well understood (at least the last time I really bothered to read up on this at all) is what it actually does, if anything, once it's there.

half-life (3, Interesting)

spikenerd (642677) | more than 5 years ago | (#28077849)

So what's the half-life of one of these bottles when full of water? Eventually, most of the BPA will be leached out, and the bottle will become safer. Does this take months, or years?

Re:half-life (5, Informative)

man_ls (248470) | more than 5 years ago | (#28078303)

The bottle itself is a polymer of Bisphenol-A sub-units. As the bottle itself naturally breaks down from exposure to light, heat, etc. the polymer sub-units are liberated into the free BPA that is a problem. As long as there's a bottle made of polycarbonate, the water stored in it will have BPA.

Not as long as the half life of this story, apparently! (I tossed my Nalgene bottle a year ago, and my coworkers were stunned I hadn't already heard of the hazard...)

Can linings (3, Interesting)

Bloody Peasant (12708) | more than 5 years ago | (#28078437)

Most canned foods (soups, beans, etc.) have a BPA-laden liner too. There was one company whose name escapes me right now that used a safer natural* lining. It's for this reason I swore off any canned soup (even the so-called healthy ones) well over a year ago.

* If you like beans, beans and more beans, this was fine, but the company didn't make the chicken soup I wanted :-(

leach? (0)

Anonymous Coward | more than 5 years ago | (#28078491)

Is it me or does the story say "leach" rather than "leak"? Did I miss something? No mods on today?
