CMA condemns Asbestos

Byoliveridley

The Canadian Medical Association Journal is denouncing the federal government for what it expects will be Canada's continued efforts to block international controls on asbestos at UN-sponsored negotiations next week.

A strongly worded editorial, appearing in tomorrow's issue of the journal, says the government "knows what it is doing is shameful and wrong" and compared Ottawa's moral stature in continuing to promote the use of the cancer-causing material to that of arms traders.

The negotiations, known as the Rotterdam Convention, are to start Oct. 27 in Rome. The focus of the talks will be on whether to add the chrysotile variety of asbestos to the world's list of most dangerous substances. Once a substance is listed, countries must give prior informed consent that they know they are buying a highly dangerous material before being allowed to accept any imports.

Canada’s national shame, its export of a killer product not used by Canadians to developing countries where the safeguards it insists on for the ‘safe” use of this product can’t possibly be carried out or enforced. For god’s sake, it’s 700 jobs, and people who can be retrained to do something that does not kill people.

  • Autism epidemic not caused by shifts in diagnoses; environmental factors likely

    Byoliveridley

    California’s sevenfold increase in autism cannot be explained by changes in doctors’ diagnoses and most likely is due to environmental exposures, University of California scientists reported. The scientists who authored the new study advocate a nationwide shift in autism research to focus on an array of potential factors in the environment that babies and fetuses are exposed to, including pesticides, viruses and chemicals in household products.

    Autism epidemic not caused by shifts in diagnoses; environmental factors likely — Environmental Health News

    One of the most common arguments you will see about a lot of mental health diagnoses is that doctors have changed their diagnostic practices significantly. While there is evidence of this occurring in diagnoses of childhood depression, anxiety, or even bipolar disorder due to the millions of dollars involved in medication and the attendant corruption, autism is different.

    This population study used 17 year data in California and concluded that diagnostic changes were only responsible for a 2 fold increase, not the seven fold increase seen. The rest is unexplained, and the authors attribute it to a confluence of environmental and genetic factors.

    And no, for the last time, VACCINES DO NOT CAUSE AUTISM!

    World Water Day – World Water Day

    As opposed to every other day when water’s not all that important! But seriously, the site is a good compendium of resources. This year’s theme is coping with scarcity. I remember when Madras had severe water shortages in the late ’80s until a couple of years back. You had to be either very lucky to live in the right neighborhood/rich enough to buy water from private tankers to fill up your water tank. Running water was off and on, we had giant buckets of stored water, it was quite an adventure for me (and a great deal of stress for my parents, of course). Those days still leave a big impression on me. Everytime I leave the tap running for more than 30 seconds, or stand in the shower for longer than necessary, I can hear my mom yelling!

    Methane Leakage, again

    Byoliveridley

    In a sane world, we would be very concerned about measuring, reporting and closely regulating methane releases during its extraction and processing, especially if we claim that it is clean energy. This is nothing I, or other people haven’t said before, but here’s more research summarized in the very respectable Nature Journal indicating that measurable leak rates of methane can vary widely.

    Preliminary results from a field study in the Uinta Basin of Utah suggesting even higher rates of methane leakage — an eye-popping 9% of the total production. That figure is nearly double the cumulative loss rates estimated from industry data — which are already higher in Utah than in Colorado

    via Methane leaks erode green credentials of natural gas : Nature News & Comment.

    10% is a large number. I’ve posted this picture from Wigley (2011) previously. At any leakage rate other than zero, which no one claims, the benefits of switching from coal to methane are very modest.

    It's all about Methane leakage
    It’s all about Methane leakage
    We absolutely need to measure, control and regulate fugitive methane emissions from every BC site, and need to have solid regulation in place before we keep expanding natural gas infrastructure. We need our political leaders to start talking seriously about capturing methane leaks when they talk about BC’s natural gas “play”.

    ES&T Online News: E-waste recycling spews dioxins into the air

    ES&T Online News: E-waste recycling spews dioxins into the air

    When computers, televisions, music systems, and other electronic products reach the ends of their lives, they often end up in China or other developing countries as e-waste. Such waste is a serious environmental threat in these parts of the world because of the poorly regulated conditions under which the waste is dismantled. A new study published in ES&T (DOI 10.1021/es0702925) shows that Guiyu, a major e-waste recycling center in China, has the highest documented levels of atmospheric polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs) in the world.

    In e-waste recycling centers in China, discarded products are dipped into open pits of acid and heated over grills fueled with coal blocks to extract precious metals, such as gold. These processes often release toxic metals, such as lead, and organic compounds, such as dioxins. The emissions are not regulated, and occupational exposure is high because of the poor working conditions for e-waste recycling laborers.

    In March 2007, researchers at Hong Kong Baptist University showed that soil at e-waste recycling sites in China has high levels of dioxins and polybrominated diphenyl ether (PBDE) flame retardants. (Read the paper at ES&T‘s ASAP website.) More recently, another study published in ES&T showed that the workers at these sites have blood levels of the heavy PBDE, BDE–209, 50–200 times higher than those previously reported. Whereas dioxins are potentially carcinogenic for humans, PBDEs affect thyroid metabolism and brain development.

    In the current study, Ping’an Peng of the Guangzhou Institute of Geochemistry (China) and his colleagues sampled the air from Guiyu for a week in both the summer and the winter and analyzed the samples for 2,3,7,8-PCDD/Fs. The levels varied between 64.9 and 2765 picogram per cubic meter (pg/m3). The toxic equivalents (TEQ)—a value used to account for the different levels of toxicity of the individual dioxins—was 0.909–48.9 pg TEQ/m3. Given that Guiyu has no municipal or medical solid-waste incinerators, which are known to be major sources of dioxins, the authors attributed the elevated dioxin levels to e-waste recycling.

    The team also found that the dioxin concentrations in the air around Guiyu were 12–18 times higher than those in Chendian, a town 9 kilometers (km) from Guiyu, and 37–133 times higher than those in Guangzhou, which is 450 km from the e-waste site. The results suggest that dioxin pollution from e-waste recycling is spreading to nearby areas.

    When they calculated the exposure of adults to dioxins through inhalation, the researchers found that it (68.9 and 126 pg TEQ per kilogram per day in the summer and winter, respectively) was a whopping 15–56 times higher than the World Health Organization recommended maximum of 1–4 pg TEQ/kg/day.

  • Judges Overturn Bush Bid to Ease Pollution Rules – New York Times

    Judges Overturn Bush Bid to Ease Pollution Rules – New York Times

    But on Friday, the court said the agency went too far in 2003 when it issued a separate new rule that opponents said would exempt most equipment changes from environmental reviews — even changes that would result in higher emissions.

    With a wry footnote to Lewis Carroll’s “Through the Looking Glass,” the court said that “only in a Humpty-Dumpty world” could the law be read otherwise.

    “We decline such a world view,” said their unanimous decision, written by Judge Judith W. Rogers, an appointee of President Bill Clinton. Judges David Tatel, another Clinton appointee, and Janice Rogers Brown, a recent Bush appointee, joined her.

    The winners this time —more than a dozen states, including New York and California and a large group of environmental organizations — hailed the decision as one of their most important gains in years of litigation, regulation and legal challenges under the Clean Air Act.

    The provision of the law at issue, the “new source review” section, governs the permits required at more than 1,300 coal-fueled power plants around the country and 17,000 factories, refineries and chemical plants that spew millions of tons of pollution into the air each year.

    The proposed rule would have allowed powerplants to avoid putting new controls in as long as the cost of equipment did not exceed 20% of the replacement cost of the plant. Fuzzy math, anyone! This would have let to major incentives to not build new plants using cleaner technology, but keep the “grandfathers” running. A lot of the old plants were exempted from some of the strict controls by being grandfathered into the act. Well, call me cruel, but grandfathers eventually die! I thought of this proposed rule as the “Bionic Grandpa” provision! Glad that the courts did not like it.

  • EU's REACH Program's cornucopia of toxicology data

    Byoliveridley

    The REACH program from the European Union is an incredibly far reaching (no pun intended, of course!) effort to catalog the effects of chemical compounds on human health. I came across this interesting article at Environmental Science and Technology.

    ES&T Online News: Will the EU’s REACH serve researchers’ needs?

    Europe’s new chemicals law, REACH (Registration, Evaluation, and Authorisation of Chemicals), will put about $13 billion worth of data on 30,000 substances onto a searchable database made available at no cost on the Internet. It sounds like a dream come true for researchers wanting to design new compounds free of the structures that cause human health hazards. But lack of funding for basic research and concerns about the competence of toxicity tests have dampened expectations among some scientists.

    Well, D’uh, any program that big is bound to have some problems. But the shifting of burden of proof away from the regulators to industry is a big deal and will lead to a lot of self regulation. Companies will have to prove that their chemicals are safe.

    John Warner, a synthetic organic chemist at the University of Massachusetts, says REACH will be effective at pushing companies to select safer alternatives that are already on the market. But for the many reagents and solvents that have no safe alternatives, safe molecules must be designed, and REACH is not structured to promote the design work, Warner says.

    Yes, this is an effort to regulate existing and new chemical entities, not an initiative to spur innovation. From the REACH site:

    The REACH Regulation gives greater responsibility to industry
    to manage the risks from chemicals and to provide safety information
    on the substances. Manufacturers and importers will be required
    to gather information on the properties of their substances,
    which will help them manage them safely, and to register the
    information in a central database.

    The innovation is going to be market driven by the fear of this regulation. Maybe we will start calling it OVERREACH!
