Bye Bye, Bisphenol A

Canada is expected to formally declare on Saturday that the controversial chemical bisphenol A (BPA) is a hazardous substance.

The move will make Canada the first country in the world to put the chemical on a list of toxic substances that will ban the material from being used in such products as baby bottles.

Good for Canada. Timing of when cans (the biggest potential source of adult exposure) will be BPA free is up in the air.

  • 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.

  • CNN.com – Caribbean coral suffers record die-off – Mar 31, 2006

    More from the global warming drumbeat, which has by now reached tipping point proportions. I was trying a few months back to predict when global warming would become a “story” in this country, something to be reported on, rather than a “debate”, I guessed middle of the year, well, I think it arrived in March with Time and Newsweek covers, and personally with at least two friends asking me about it. News coverage of climate change has changed completely in the last few months as observations catch up with the modeling, as they do most of the time. But  people like to see proof, not model simulations which can always be explained away, well, here’s more proof…

    CNN.com – Caribbean coral suffers record die-off – Mar 31, 2006
    The Caribbean is actually better off than areas of the Indian and Pacific ocean where mortality rates — mostly from warming waters — have been in the 90 percent range in past years, said Tom Goreau of the Global Coral Reef Alliance. Goreau called what’s happening worldwide “an underwater holocaust.”

    And with global warming, scientists are pessimistic about the future of coral reefs.

    “The prognosis is not good,” said biochemistry professor M. James Crabbe of the University of Luton near London. In early April, he will investigate coral reef mortality in Jamaica. “If you want to see a coral reef, go now, because they just won’t survive in their current state.”

    For the Caribbean, it all started with hot sea temperatures, first in Panama in the spring and early summer, and it got worse from there.

    New NOAA sea surface temperature figures show the sustained heating in the Caribbean last summer and fall was by far the worst in 21 years of satellite monitoring, Eakin said.

    “The 2005 event is bigger than all the previous 20 years combined,” he said.

    What happened in the Caribbean would be the equivalent of every city in the United States recording a record high temperature at the same time, Eakin said. And it remained hot for weeks, even months, stressing the coral.

    Jeffrey Sachs on climate change induced water shortages

    Depressing reading for a Sunday morning. He does not offer too many solutions, but it will take a lot of local work to mitigate these disasters. Of course, I can’t see the US or Europe offering asylum to climate change refugees!

    Climate Change Refugees: Scientific American

    Human-induced climate and hydrological change is likely to make many parts of the world uninhabitable, or at least uneconomic. Over the course of a few decades, if not sooner, hundreds of millions of people may be compelled to relocate because of environmental pressures.

    To a significant extent, water will be the most important determinant of these population movements. Dramatic alterations in the relation between water and society will be widespread, as emphasized in the new report from Working Group II of the Intergovernmental Panel on Climate Change. These shifts may include rising sea levels, stronger tropical cyclones, the loss of soil moisture under higher temperatures, more intense precipitation and flooding, more frequent droughts, the melting of glaciers and the changing seasonality of snowmelt.

    Flame Retardants and Hyperthyroidism in Cats

    Caveat Emptor: They found a correlation, not a causative mechanism. But Polybrominated Diphenyl Ethers (PBDEs, yum!) have structures that can mimic endocrine hormones. Because hormones signal at very low doses and continuously, our whole toxicological risk testing structure of looking for acute effects at high doses and trying to extrapolate those effects to low doses is flawed for endocrine disrupting compounds. We are finally beginning to see some new research, especially with other toxics such as Bisphenol A, which test for chronic conditions and subtle gene and hormonal signalling effects at low doses. After all, small changes in hormone regulation especially at childbirth and a young age can have very serious effects later on in life.

    Inside Bay Area – NEW: Flame retardants linked to thyroid disease in cats

    A mysterious epidemic of thyroid disease in cats may be linked to flame retardants common in carpets, foam furniture and mattresses, according to U.S. Environmental Protection Agency researchers, who suggest that scientists have underestimated the damaging health risk the chemicals pose to humans.

    The research, published Wednesday in the journal Environmental Science and Technology, does not prove these compounds, known as PBDEs, caused the rash of hyperthyroidism in the nation’s household cats over the past 30 years.

    Rather, it lays out a hypothesis, showing that cats are heavily contaminated by these compounds, which leach from household products and are found everywhere, particularly household dust. Cats, meticulous cleaners, ingest PBDE-contaminated dust daily.

    The case of fire retardants is especially difficult because they save many lives, so manufacturers can always point to that fact and resist change. The logical fallacy, however is as follows:

    1. Fire retardants save lives (therefore good)
    2. PBDEs are fire retardants
    3. Therefore, PBDEs are good!!

    The search for a safer fire retardant needs to continue, and will not happen unless the old ones are under pressure of being phased out.

    What's the matter with Canada?

    But beneath the calm exterior, Canada’s political system is in turmoil. Since 2004, a succession of unstable minority governments has led to a constant campaign frenzy, brutalizing Canada’s once-broad political consensus and producing a series of policies at odds with the country’s socially liberal, fiscally conservative identity. Canada is quietly becoming a political basket case, and this latest election may make things even worse.

    What’s the matter with Canada? – By Christopher Flavelle – Slate Magazine

    I don’t necessarily agree with the whole “basket case” assertion, it is a fundamentally strong country with a broad consensus on what the country should be.

    The current set of political parties is rewarding a minority set of policies (the conservatives) by fragmenting the majority centre-left of centre consensus between 4 different political parties, none of which will talk to each other. This is not exactly new, the conservatives only merged their parties a few years back.

    The liberals suffer from Dion’s non Englishness, he gets little traction from the English media (no idea about the French, I don’t know any). He’s not that charismatic, nor does he orate well in English, and so like the American election, it is all optics. The liberals also seem to have no understanding of what it takes to win a modern election. The conservatives get in the news all the time, their ads are all over TV, the liberals seem to be MIA.

    Harper on the other hand is “strong”, strength of course being defined as sounding decisive and declaratory, even though he usually just sounds alarmist and hyperbolic all the time. Somehow, this is interpreted as leadership. I guess the only good quality of leadership is being loud.

    Dion also made a gamble by selling something called the Green Shift, a carbon tax, to increase efficiency in energy consumption and reduce greenhouse gas emissions. Even though the tax is designed to increase efficiency in a country notorious for its very poor efficiency (27th among the 29 OECD countries in energy use/capita), it is being demonized as a tax that will destroy the country (just like every other environmental regulation destroyed every other country). It is also bad timing, as energy prices have soared recently, and Canada’s economy sputters to a halt due to falling resource prices and the American housing market bust (destroyed the BC lumber industry). The last thing people want to hear is “tax”, even though the middle class will get more than sufficient rebates to cover any tax increases. The liberals seem to have overplayed this hand. Elections are never won on environmental issues, too easy to attack.

    The conservative pitch thus far has only been to attack Dion while offering some incremental changes. But as Harper is flirting with a majority, this Toronto Star editorial asks the right questions.

    While Harper is presenting himself as a kinder, gentler Conservative these days, in the past, as a Reform MP, head of the National Citizens’ Coalition and leader of the Canadian Alliance (successor party to Reform), he staked out quite radical positions. He has called Canada “a northern European welfare state in the worst sense of the term,” has denounced the “moral nihilism” of the Liberals and the left for opposing the Iraq war, has suggested building a “firewall” around Alberta, and has called for “market reforms” for health care, “further deregulation and privatization,” and “elimination of corporate subsidies.”

    With a Conservative majority in sight, it is fair for Canadians to ask Harper whether he still holds these views and would implement them once in office. And if the answer is No, Harper should use the remaining four weeks of this election campaign to tell voters just what he would do with a majority.

    The media lets Harper get away with sounding “presidential”, his proposals are very vague, and that is worrying. It is clear, however, that from an environmental standpoint, he will be a disaster. A combination of a slowing economy and reduced social support programs (conservatives hate safety nets for regular people) will be bad for the not so well off Canadians. We shall see what happens in a few weeks.

  • Voluntary Priority and Toxic Chemical Reduction – US EPA

    Priority and Toxic Chemical Reduction | Resource Conservation Challenge | US EPA

    Priority and toxic chemicals make up a fairly limited volume, yet potentially hazardous portion of the nation’s waste stream. We are working to eliminate or reduce priority chemicals and other chemicals of national concern from commercial products, waste streams, and industrial releases through pollution prevention, waste minimization, and recycling/reuse.The 31 priority chemicals are federal priorities because they are persistent, bioaccumulative, and highly toxic. We’re focusing on reducing priority and toxic chemicals to better protect human health and the environment.

    By substituting or eliminating certain chemicals in their manufacturing processes, companies produce less waste and thus lower their waste disposal costs. Our goal is to substantially reduce the volume and toxicity of priority chemicals in waste by asking companies to voluntarily:

    • Substitute safer alternatives when they can;
    • Minimize the amount of priority chemicals they use, if they can’t substitute for them;
    • Maximize their recycling efforts;
    • Practice cradle-to-cradle chemical management; and
    • Design products to minimize exposure to, and release of, priority chemicals during manufacturing and use.

    Sounds good, and Worldchanging has more:

    But nowhere near the progress some companies are making on their own in cleaning up toxic emissions — not simply to be good guys, but to reduce their costs, liabilities, and exposure to activist and shareholder pressures. And, in some cases, to meet their customers’ growing demands for less-toxic or nontoxic alternatives to business as usual.

    Read the whole post, which sounds ambivalent about the scheme. The idea is Environmental Good Sense 101, use less, or none at all, practice cradle to grave economics and minimize exposure. Simple stuff, huh. The biggest problem, however, is that by setting limits on a voluntary basis, you always run the risk of setting the bar too low, and then indulging in relentless and pointless self congratulation about how the “market” solved everything, and how rules are so, well, 1970s?

    you need a good mix of

    1. Regulation, which sets a minimum, health based bar
    2. Flexibility to the business on how to achieve their targets
    3. Market systems to trade emission credits, etc
    4. Voluntary industry-government initiatives like the one above
    5. Relentless citizen activism that forces governments/business to act
    6. Community outreach and education so consumers can make informed choices
    7. Costing mechanisms that actually reflect free market efficiencies (no stupid subsidies, accurate costing of “externalities”, etc. )

    Yeah, this does not fit neatly into the Mano a Mano, you’re with us/you’re against us false dichotomy of choice that seems to beset almost every policy debate (environmental or otherwise). It seems that you never have to do one or the other, but a bit of both, or all of them at the same time.

    In the meanwhile, the voluntary program will work, but only in areas in specific instances where it is to a company’s advantage.

    BTW, I think that good old fashioned regulation in Europe – See Reach and many many more existing regulations, such as this one for PCBs and Dioxins which I know a little too much about, have a little more to do with American companies reducing POP levels that they care to admit!
