What next, poison that kills entire swathes of people? I know that Night Shyamalan’s The Happening was panned for its atrociousness, but hey, the man is a prescient science fiction turns to fact maven if this story is any indication.

Plants facing stressful conditions like drought produce their own aspirin-like chemical, US researchers say.

The chemicals are produced as a gas to boost the plant’s biochemical defences, say scientists from the National Center for Atmospheric Research in Colorado.

  • EPA scales back rules on wetlands

    Where for the n’th time, you get to use “EPA”, and “scales back rules” in one sentence.

    E.P.A. Scaled Back Rules on Wetlands – New York Times

    After a concerted lobbying effort by property developers, mine owners and farm groups, the Bush administration scaled back proposed guidelines for enforcing a key Supreme Court ruling governing protected wetlands and streams. The administration last fall prepared broad new rules for interpreting the decision, handed down by a divided Supreme Court in June 2006, that could have brought thousands of small streams and wetlands under the protection of the Clean Water Act of 1972. The draft guidelines, for example, would allow the government to protect marsh lands and temporary ponds that form during heavy rains if they could potentially affect water quality in a nearby navigable waterway. But just before the new guidelines were to be issued last September, they were pulled back in the face of objections from lobbyists and lawyers for groups concerned that the rules could lead to federal protection of isolated and insignificant swamps, potholes and ditches.

    This is the consequence of a tortured Supreme Court ruling from June of last year where Justice Kennedy could not make up his mind on what was a wetland and what was not, so he helped hand down a very confusing verdict open to all kinds of interpretation. At that time, here’s what I said…

    This will make things confusing for a while, and you all know who confusion favors!

    Well, I told ya!

  • 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!

    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.

  • 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!

  • Canada and Greenhouse Gases – Epic Fail

    Canada’s greenhouse emissions soaring: UN report

    The figures are based on the 2009 national inventory report that Environment Canada quietly filed last week with the United Nations to meet its international reporting obligations. The full 673-page inventory is available on the UN’s website and shows Canada has the dubious distinction of having its emissions climb more since 1990 than any other G8 nation.

    Canada ranks “first among the G8 nations” for increasing emissions, the report notes, even though Canada had committed to cut them. It notes that while Canada’s emissions have soared, Germany chopped its emissions by 18 per cent between 1990 and 2006, and the United Kingdom slashed its by 15 per cent.

    Hey, we’re first in the G8 in something! The increase was driven primarily by increasing Tar Sands emissions thanks to the oil boom. Cars and coal also contributed.

    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.
