Health Canada report ties asbestos to lung cancer

Health Canada sat for more than a year on a report by a panel of international experts that concludes there is a “strong relationship” between lung cancer and chrysotile asbestos mined in Canada.

Health Canada received the report in March 2008, resisting calls from the panel chairman to release the findings despite his plea last fall that the delay was “an annoying piece of needless government secrecy.”

Canwest News Service obtained the report under Access to Information legislation, but the request took more than 10 months to process.

Vancouver Sun

Yes, dog bites man anywhere else except Canada, which has a hard time accepting that it routinely exports products that kill people. The “annoying piece of needless government secrecy” is neither needless or annoying. It protects a dying industry with a few, powerful stakeholders in Quebec, an important swing political province, so there’s need for it! Annoying – your seat “buddy” on the bus yammering on their cellphone, cancer, well, I don’t know, you tell me!

Expect little to change from this report. It does mention that there is little danger from “Canadian exposure levels”, conveniently forgetting that 90% of the export is to developing countries where there are fewer safeguards. This feeds into the Canadian government line that “chrysotile” is safe if used correctly. If you think this line of reasoning is familiar, it is. The tobacco industry used it routinely till recently.

Shame.

    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.

    Coffee Roasting and Popcorn Lung

    Cross-posted from Interrobang

    Who among us coffee drinkers don’t love the smell of freshly roasted coffee? I am sure some of us imagine how much fun it would be to smell freshly roasting coffee more often. I don’t, because smell for me is an instant jolt of pleasure/pain followed by a rather rapid decline into the background.

    Caution, though. New measurements from the US Centres for Disease Control warn of high exposure to some pretty nasty chemicals that can cause your lungs to be destroyed irreversibly, the unfortunately named “popcorn lung” or bronchitis obliterans:

    Investigators with the National Institute of Occupational Safety and Health, a research arm of the CDC, spent several days at Madison-based Just Coffee in July. Investigators tested personal air space and took air samples to measure the concentration of the chemicals diacetyl and 2,3-pentanedione… NIOSH researchers found levels in three breathing-zone samples that exceeded the safety levels recommended by the CDC.

    Coffee Roasting Plants and Exposure

    The test results show a marginal exceedance in this case, but noted that ventilation is a big factor and these tests were done under well ventilated conditions on a warm and dry day when doors were open. So, exposure can be higher in other circumstances.

    Worker exposures are to higher levels, and are more sustained, so they deserve the most attention.

    So, local coffee roasters, it may make sense to confirm that your roasting environments are not exposing your workers to harmful, lung obliterating chemicals. Remember, organic, shade grown, fair pay, artisanal roasting aside, chemical exposures to workers don’t change. And, everything that smells good isn’t good for you.

    One of my frequent points of emphasis (rants, some might say) is on the relative risk vs. media attention to exposures of people to ambient, day to day concentrations of potential harmful chemicals vs. those faced by workers everywhere. The last time diacetyl and bronchitis obliterans were in the news, it was around the use of diacetyl to produce that buttery smell so beloved in microwave bag popcorn (I don’t like it myself, olive oil all the way!). Despite reports of many workers facing severe lung issues, it took the detection of the disease of one person eating multiple bags of microwave popcorn over many years to actually move government regulators into action on diacetyl. People who work in factories, in the fields, and make things are exposed to thousands of times higher concentrations of harmful chemicals for longer periods of time, but their concerns are often de-emphasized.

    This doesn’t mean ambient exposures in the general population are to be ignored, but worker exposures are to higher levels, and more sustained, so they deserve the most attention.

    16-May-2016 Update

    This US Centers for Disease Control page is a good collection of information and further readings. They recommend facility tests to measure diacetyl and its cousin 2,3-pentanedione, and better ventilation, worker safeguards and personal protective equipment as necessary. They also note that at least five workers in large scale coffee processing plants have been diagnosed with bronchitis obliterans.

    The US guts Environmental Assessments

    Environmental assessment in the U.S. was enshrined in law for the first time when President Richard Nixon signed the National Environmental Policy Act (NEPA) on January 1, 1970. Since then, however, the U.S. has slowly cast aside its role as a leader in the field of environmental assessments, as successive administrations have chipped away at the scope of NEPA, experts say. The cuts have reached a crescendo with President George W. Bush’s administration, and proponents of these assessments worry that pressure to develop natural resources with little oversight of the consequences will lead to an unsustainable future for the U.S.

    ES&T Online News: Environmental Magna Carta under siege

    Well, perfect. Now you can claim very factually that “you don’t know of any harmful effects of your actions”.

    The fact is, the attack on NEPA has come, chronically, from a relatively small group of commodity users—timber companies, highway builders—who simply oppose having the public and environmentalists get in the way of their plans and programs,” Houck maintains.

    Can’t say it any better. Information is very important and one thing this Bush administration has been very successful at is reducing the flow of information.

    Jeffrey Simpson and Lazy Writing aka I wrote a letter to the editor

    Jeffrey Simpson wrote an interesting article on the politics of tarsands pipelines that had some good insights:

    • Harper lecturing Obama on playing politics is a bit rich
    • The opposition is multi-faceted, not just based on the carbon footprint
    • The opposition is widespread, and opposition is not tarsands specific, but against expanding fossil fuel in a world poised to warm at an ever increasing rate
    • Tarsands oil is dirty oil, and no amount of lobbying can take that away
    • Alterate pipeline routes such as Enbridge’s Northern Gateway are not going to be easy to construct given significant First Nations’ opposition

    It was on the last point that Jeffrey Simpson’s otherwise useful Op-Ed degenerated into what can be charitably described (by a PR hack) as an “unwise choice of words”.

    The route must traverse huge tracts of land claimed by aboriginals who, for a variety of reasons, don’t want a pipeline. Maybe they’re pigheaded. Maybe they don’t want to join modernity.

    This is insulting and ignorant to begin with. Surely Jeffrey Simpson does basic research before he writes these columns, and google searches will reveal many many articles, including one in the newspaper that pays his salary that clearly explain the rational reasons behind First Nations’ concerns on pipelines. Simpson seems to have no trouble finding rational reasons to buttress other opposition claims. He says Nebraska’s opposition was due to the pipeline passing over environmentally sensitive areas. He also uses a Royal Society of Canada report judging Canada’s green house gas mitigation efforts as inadequate to make a larger point about the pollution caused by the tarsands and fossil fuels.

    However, for First Nations’ concerns alone, he resorts to the irrational, tired and racist tropes of First Nations people being “pigheaded”, or “opposed to modernity”. What exactly is Mr Simpson trying to imply?

    I was angry enough to dash a letter off to the Globe and Mail, which they promptly published, thanks folks.

    Here’s what they published

    Jeffrey Simpson’s column (Pipe-Altering Lessons – Nov. 16) offers some good insights into pipeline politics and government hypocrisy and states accurately that people are opposed to most fossil fuel expansion, not just the oil sands. However, his speculation on First Nations’ opposition to the Northern Gateway project as “pig headed” or not wanting “to join modernity” are offensive and misstate the valid concerns voiced by more than 60 indigenous communities. They are concerned about irreparable damage to the land and salmon migration routes and are well aware how little of the large profits made by energy companies accrues to the First Nations whose land these projects are frequently based on. Their reasons are well founded and well documented by many First Nations, including the Wet’suwet’en.

    Here’s what I wrote.

    If Mr Simpson were a little less “pig headed”, or “more willing to join modernity”, he would fire up that marvellous modern invention, the web browser and look up wetsuweten.com. His unnecessary slurs take away from what is a otherwise a sensible and well written article.

    They did leave out my rather snarky last paragraph 🙂

    People way ahead of politicians on smoking

    Dear state politicians, if you can’t lead, can you at least follow?? If you have not been following this issue, click here. North Carolina recently failed to pass a smoking ban in bars and restaurants.

    More than two-thirds of North Carolina adults favor a statewide ban on smoking in public enclosed areas, such as restaurants, stadiums and shopping centers, according to a new poll by researchers at UNC-Chapel Hill.

  • EPA Faces major Challenges, and no money

    At a time when this country faces major environmental challenges, including catching up with the rest of the developed world on global warming, the agency that would have to do the heavy lifting on environmental regulation ain’t getting the money to do diddley squat. A 25% cut in inflation adjusted terms over 4 years is huge, especially considering that the EPA was not a cushy agency even before that.

    ES&T Online News: Budget cuts increasingly damaging to EPA

    Support for research and development at EPA has declined by 25% in inflation-adjusted terms between the recent high point in 2004 and the proposed 2008 budget, according to figures from the American Association for the Advancement of Science.

    “Morale has never been so low here since the days of Ann Gorsuch, and even then there was more money,” says one scientist, referring to the time during the early 1980s when former administrator Gorsuch, who resigned under a cloud, did her best to shrink the agency.

    But George Gray, assistant administrator for the agency’s Office of Research and Development (ORD), says he fully supports the proposed budget. “This budget fulfills every presidential environmental commitment and maintains the goals laid out in the EPA’s strategic plan, while spending less,” he says. The budget cuts come on the heels of EPA’s program to cut $2 million from the agency’s fund for specialized libraries.

    The scientists’ difficulties are likely to increase if the proposals in a June 2006 memo from Lyons Gray, EPA’s chief financial officer, are carried out. The memo, which was released by the advocacy group Public Employees for Environmental Responsibility (PEER) directs ORD to reduce laboratory physical infrastructure costs by a minimum of 10% by 2009 and another 10% by 2011. The memo suggests that this will require closing, relocating, and consolidating EPA’s laboratory and field locations, as well as reducing or relocating staff. ORD chief George Gray told Congress that EPA does not intend to shut down any labs or get rid of any scientists during the current administrator’s tenure.

    The U.S will pay the price for this deliberate destruction of government infrastructure. You won’t see it now, it will be a little more apparent in a few years.
