Oil refineries underestimate release of emissions, study says

Byoliveridley

A study by the Alberta Research Council that investigated the plume of contaminants emanating from a Canadian oil refinery using high-tech sniffing equipment found the facility dramatically underestimated its releases of dangerous air pollutants.The refinery, which wasn’t identified but is believed to be in Alberta, released 19 times more cancer-causing benzene than it reported under Environment Canada disclosure regulations, about 15 times more smog-causing volatile organic compounds, and nine times more methane, a greenhouse gas, according to the study.The testing is believed to be the first at a North American refinery using the sophisticated technology relying on lasers, and is considered state-of-the art. The technology, developed by British Petroleum, has been in widespread use in Europe for nearly two decades.

globeandmail.com: Oil refineries underestimate release of emissions, study says

Serious stuff, this. As the report points out, this is old news, here’s a workshop report from the EPA last year about this very issue (no, don’t read it, 303 pages long). Volatile organic compounds are inputs into air pollution models that measure ozone levels. When your local agency tells you that Tuesday is going to be a code orange ozone day, they rely on ozone models such as CMAQ. Now, without proper inputs, you are going to make some serious errors in prediction. These errors are somewhat mitigated by the tuning of these models with measured concentrations. So, there is some error compensation going on within the model.

More importantly, by underestimating fugitive emissions, refineries can reduce their leak monitoring, reporting and mitigation costs. There is also the issue of conflict of interest here. The current technique was developed by the American Petroleum Institute!

Do we expect measurement based techniques to start being used in the US and Canada? One would hope so, but, don’t hold your breath!

  • Pesticides

    farmerA friend pointed me in the direction of this letter by EPA union leaders about the upcoming re-registration of some very commonly used organophosphate and carbamate pesticides. This ens-newswire article provides an excellent summary.

    In the absence of “a robust body of data” the union leaders remind Johnson that the Food Quality Protection Act requires the EPA to use “an additional 10-fold safety factor in its risk assessments when setting pesticide tolerances.

    This is the key point, and the reason that Pesticide industry and the EPA came up with the infamous “CHEERS” study (talk about Kafkaesque naming!) to study children’s exposure knowing fully well that they would not be able to accurately assess health effects on children with an observational study. The hope was that using a short term “study” that assessed acute toxicity, they would be able to “prove” no significant harm to children and get rid of the safety factor. A factor of 10 is big, and the pesticide manufacturers hate it because the tolerances become low enough that people will be over-exposed.

    Isn’t that the whole point of a safety factor? We are still figuring out what happens at low levels of exposure to certain pesticides. This is truly an Environmental Justice issue. It is not the children of EPA administrators eating non-organic fruits and veggies that are going to be exposed. The gains from eating organic food vs. non-organic are dwarfed by the incidental exposure of the families of farmworkers and other people applying pesticides. Yes, you guessed it, they do not tend to be particularly rich or influential, but they are most in need of protection from government to ensure that their children do not get exposed to levels that may be harmful. This is not about shopping at Whole Foods, which is where most of elite America hears about pesticides, this is about the people being exposed to much higher doses. The safety factor is a must to keep them safe.

  • The “World Trade Center Cough”

    Lung problems rife among WTC responders – Yahoo! News

    NEW YORK – Nearly 70 percent of recovery workers who responded to the attacks on the World Trade Center suffered lung problems during or after their work at ground zero, a new health study released Tuesday shows. Less than a week before the anniversary of the Sept. 11, 2001, terrorist attacks, Mount Sinai Medical Center issued the results of the largest study on related health effects. It found, among other things, that the ailments tended to be worst among those who arrived first at the site, and that high rates of lung “abnormalities” continued years later. The study focused mostly on what has been dubbed “World Trade Center cough,” which was little understood immediately after the attacks but became a chief concern of health experts and advocates.

    Not surprising at all, considering all the fine particles, asbestos, PAHs, elemental Carbon, PCBs, and numerous other nasties that were released in a couple of catastrophic explosions, and the utter unpreparedness of the first responders, who were, after all, going in to save other peoples’ lives, not looking out for the air they were breathing. Calling this major air pollution related health disaster the “World Trade Center Cough” is a little like calling World War II the “Skirmish with Germany, Part Deaux”, but what do I know about the power of language and framing!

  • Canada's Enduring Environmental Shame

    Byoliveridley

    When 500 ducks died earlier this month after landing on a tar sands tailings pond, Canadians got a glimpse into how unfettered tar sands development is taking its toll.Members of the Mikisew Cree and Athabasca Chipewyan First Nations living downstream from the massive industrial projects have been feeling the effects for a lot longer.The backyard of the tiny community of Fort Chipewyan, Alberta contains the second largest reserve of petroleum in the world. The tar sands development is Canada’s fastest growing source of greenhouse gas emissions, the cause of rapid pollution of the Athabasca river basin, the reason for strip mining of thousands of square kilometres of boreal forest; a huge consumer of natural gas, and the likely cause of alarming rates of cancer in nearby Cree communities.

    More on this later, but for all its feel good actions in other areas, the Tar Sands are, and will remain Canada’s symbol of hypocrisy when it comes to the environment.

    Flame Retardants and Hyperthyroidism in Cats

    Byoliveridley

    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.

    Nissan Shows Off Its Electric Car, the Leaf – NYTimes.com

    What, no Canada? But still,  an electric hatchback, hits all my buttons and dings all my dongs! I only hope to keep my current, explosion powered hatchback long enough to not buy one ever again. Price, of course, will be a consideration. The good news is that Nissan is considering leasing the battery instead of people having to buy it up front, a great idea, not as great as the battery instant replace model from Shai Agassi and Better Place, but one that lessens the battery buying burden.

    The future is electric.

    Lead and Crime

    Byoliveridley

    leadcrime.jpg

    The next time Giuliani tries to take credit for the decrease in violence during his tenure as NYC’s mayor, send him this chart.

    The NY Times shines some light on Jessica Reyes’ excellent work linking decreased lead exposure to a drop in violent crime in the US. The decreased lead exposure, of course, was from the phase-out of leaded gasoline from the American market. BTW, Nascar still uses leaded gasoline in its cars, nice going, guys.

    The answer, according to Jessica Wolpaw Reyes, an economist at Amherst College, lies in the cleanup of a toxic chemical that affected nearly everyone in the United States for most of the last century. After moving out of an old townhouse in Boston when her first child was born in 2000, Reyes started looking into the effects of lead poisoning. She learned that even low levels of lead can cause brain damage that makes children less intelligent and, in some cases, more impulsive and aggressive (Emphasis Added).

    Lead exposure at an early age (2-3 years) is especially significant as this is an age where personality development occurs and any interference in neuron development and apoptosis (death!) can cause permanent changes in personality. This excellent review article summarizes the effects of lead on neuronal development.

    Reyes’ research mentions that while decreased lead exposure was very well correlated with violent crime (accounting for 56% of the reduction in crime), no correlation was found to property crimes (such as theft). This of course makes intuitive sense. A property crime is usually premeditated whereas violence is usually impulsive (excluding serial killers, of course). It is more likely that a budding criminal sets out to steal a car than to beat somebody to pulp. It is when the crime goes wrong that the probability of a violent crime increases. An individual with damaged impulse control is then more likely to seek a violent way out of the bad situation.

    Our society (like most) views violent crime as a moral issue, a matter of good and evil that is determined by your “character”. So, a simple chemical correlator to violent crime that can explain a majority of the commission of violent acts goes a long way in undermining this whole notion of morality and crime. Of course, there are other sociological factors at play which need to be addressed. But it is heartening to know that beyond all the complicated and recalcitrant social issues that underly crime, there’s a ubiquitously evil pollutant lurking that can be eliminated. I am guessing that this line of reasoning is not going to be very popular among the “tough on crime” types that perpetrate our political airwaves these days.
