EPA Calls for End to Releases of Chemical in Teflon Process

Check out this story from the January 26, 2006 LA Times.

In a rare move to phase out a widely used industrial compound, the Environmental Protection Agency announced Wednesday that it was asking all U.S. companies to virtually eliminate public exposure to a toxic chemical used to make Teflon cookware and thousands of other products.

EPA’s system of regulating chemicals leads to some really perverse incentives. The burden of proof shifts to the EPA to prove beyond reasonable doubt that a chemical has definite harmful effects on humans at ambient exposure levels. So the preferred route has been for the EPA to “suggest” to the companies to participate in a voluntary phaseout.

No one knows how the chemical is getting into people’s bloodstreams and in the bodies of polar bears and other animals. Although it is used in production of cookware, it is not found in the cookware, clothing and other fluoropolymers after manufacture.

Well, not quite. This from a paper published in the Environmental Science and Technology on January the 25th.

Polyfluorinated telomer alcohols and sulfonamides are classes of compounds recently identified as precursor molecules to the perfluorinated acids detected in the environment. Despite the detection and quantification of these volatile compounds in the atmosphere, their sources remain unknown. Both classes of compounds are used in the synthesis of various fluorosurfactants and incorporated in polymeric materials used extensively in the carpet, textile, and paper industries. This study has identified the presence of residual unbound fluoro telomer alcohols (FTOHs) in varying chain lengths (C6-C14) in several commercially available and industrially applied polymeric and surfactant materials…

This study suggests that elimination or reduction of these residual alcohols from all marketed fluorinated polymers and fluorosurfactants is key in reducing the prevalence of perfluorinated acids formed in the environment.

Well, that explains it a little better, this article from ES&T provides a nice executive summary like context.

An emerging theory that explains how PFOA (perfluorooctanoic acid) and other PFCAs (perfluorocarboxylic acids) have contaminated the Arctic has received a boost from a new modeling study published in this issue of ES&T (pp 924–930). The theory contends that Arctic contamination is due to atmospheric transport and breakdown of fluorotelomer alcohols, chemicals that are used in products that include stain protectors, microwave-popcorn bags, fast-food wrappers, polishes, and paints.

Well, it sure looks like we need to focus much more on the PFOA precursors rather than on the PFOA itself. Dupont and 3M are not going to be happy about that!

  • The Onion on Conservation

    This is so sad, though there is more than a kernel of truth to it. Individual efforts mostly make people feel better about themselves (hey, I recycle, makes me feel good!). It is the Onion and it does go too far. Of course individual efforts add up, and more importantly, force the important players like government and big industry to modify their behavior just a little bit (at least that is what I tell myself).

    I’m Doing My Inconsequential Part For The Environment | The Onion – America’s Finest News Source

    Every day, without fail, I meticulously organize my recyclables into five distinct categories, thereby subtracting an eyedropper’s worth of garbage from the countless tons of waste that ferment in our landfills. It only takes a few extra minutes, but just think of the impact it totally lacks. I also refuse to use anything but “Earth-friendly” paper products—some of which contain up to 10 percent recycled materials. For me, it’s worth shouldering the extra cost, but, unfortunately, only a scant few of us bother to do the same. And growing some of my own organic vegetables in my backyard garden also, to my immense gratification, reduces the use of toxic chemical-based pesticides and herbicides present in corporate farming techniques by as much as 0.0000000000000000000000000000000000000001 percent.

    Split court rules against Bush on greenhouse gases – CNN.com

    Interesting, see here for background…. So, the Supreme Court has ruled that CO2 is a pollutant, good for them.

    Split court rules against Bush on greenhouse gases – CNN.com

    The Supreme Court ordered the federal government on Monday to take a fresh look at regulating carbon dioxide emissions from cars, a rebuke to Bush administration policy on global warming.

    In a 5-4 decision, the court said the Clean Air Act gives the Environmental Protection Agency the authority to regulate the emissions of carbon dioxide and other greenhouse gases from cars.

    Greenhouse gases are air pollutants under the landmark environmental law, Justice John Paul Stevens said in his majority opinion.

    The court’s four conservative justices — Chief Justice John Roberts and Justices Samuel Alito, Antonin Scalia and Clarence Thomas — dissented.

    Kennedy, swung left on this one! I stand by my original asseesment, just regulating cars using the clean air act is inadequate, but the important matter resolved here is that CO2 is a pollutant, and this will, I hope, provide precedent in cases to come.

    Lead in Paint, why???

    1940-11_White_Lead_Paint.JPGThis makes my head explode, once again, science is helpless when faced with inertia, and greed. Lead-based paint has been banned in the US since 1978, and if this story is any indication, we’re still seeing the effects of peeling paint. But this bit of research from the University of Cincinnati suggests that not only is lead-based paint being used in more than half the world, it is actually legal.

    Study Supports ‘Urgent’ Need for Worldwide Ban on Lead-Based Paint

    Environmental and occupational health experts at the University of Cincinnati (UC) have found that major countries—including India, China and Malaysia—still produce and sell consumer paints with dangerously high lead levels.

    Why would anyone need to use lead-based paint when alternatives have been available for the longest time, the health effects of lead, especially on children, are very well known, and there is no @#$%^&*# reason other than greed and unwillingness to change. What is the point of all these years of research if it makes no difference at all to the bulk of the world’s population? Depressing.

    Guess what, even if lead-based paint was banned today, it’s still going to be on the walls forever. As the paint peels, kids will be exposed, have lowered IQ, and all other kinds of health issues for as long as that house is standing, which in India could be a 100 years.

    Grassroots organizing is probably needed, and if effective, the stuff will be banned in India quickly, the government does move rapidly on these kinds of easy to legislate issues. But, enforcement will be lax, and awareness will lag, which means we are looking at (my rough guess) at least 20 years more of this issue.

    Once again, the absence of a ban and its implementation affects the poor and uneducated disproportionately. The way I see it happening in India is

    1. Some grassroots awareness, media stories, etc.
    2. A furore that lasts about a week, before the next big story comes along
    3. Maybe a government action that will “ban” lead-based paint
    4. The middle class and above are now aware that they can use titania based paints, so, a quick change for them.
    5. Everyone else is still stuck with the lead-based paint.

    And this does not even begin to address what the US is going through now, aging houses, peeling paint, poor people being exposed to dangerous levels of lead.

    The world ain’t very fair…

  • Wow, Conventional Milk makes Twins!

    44m.jpgHoly tentacular twins, Batman! This is crazy news, the first study linking the incidence of twins with environmental factors. The culprit is growth hormone fed to cows to increase milk production. According to this Wikipedia article, a third of all dairy cattle use Monsanto’s rBGH (or rBST) brand Posilac®, so obviously, use is widespread.

    FEED – July 2006 (from the Union of Concerned Scientists)

    1. Engineered hormone in milk may be linked to twinning. A recent study found that women who consumed dairy products were five times more likely to give birth to twins than vegan women. The study suggested that the use of engineered bovine growth hormone/bovine somatotropin (BGH/BST) to boost milk production in dairy cows may be related to the higher level of twinning. BGH is known to increase twinning in dairy cows. In addition, the rate of human twinning is twice as high in the United States, where BGH is used, as in Britain, where BGH is banned. BGH affects twinning rate by increasing insulin-like growth factor (IGF), a protein produced in the milk of both animals and humans, that promotes ovulation and may help early-stage embryos survive. A separate study found that levels of IGF were 13 percent lower in vegan women than in women who consumed dairy products. Read a press release about the study, which was published in The Journal of Reproductive Medicine.

    If true, no woman should ever drink “conventional” milk (non-organic, non rGBH free, etc). Twins are fun, I love my twin nieces very much, but they are much more difficult to carry and deliver, and there are more complications.

    Scary, but I suspect this is the tip of the iceberg as far as environmental effects on childbirth are concerned.

  • E.P.A. to Regulate greenhouse gases

    The Environmental Protection Agency has moved to declare that greenhouse gases are pollutants that pose a danger to the public’s health and welfare. That determination, once made final, will pave the way for federal regulation of carbon dioxide, methane and other heat-trapping gases linked to global warming.

    via NY Times

    Of course, this action was required by a US Supreme Court decision on greenhouse gases last year and provides the regulatory side to the push that must come from congress.

    There have been recent rumblings that the US Congress would shelve climate change for 2010. While this would please some Americans in the short term, the idea of the US going into the Copenhagen climate change conference without a GHG reduction plan out on the table leaves me very dispirited. The timing of the EPA’s announcement suggests that there might be some pressure from the EPA to get Congress to act. It is clear that the EPA does not have breadth of scope to pull of climate change regulation using a rule making process. Maybe if it starts trying, American politicians may get their act together.

    Clutching at straws…
