Grad student measures hazardous levels of air pollution at cigar show

Byoliveridley

Sure makes my graduate work in air quality seem a little tame!

The man behind the subterfuge (Researcher 2, male) was Ryan David Kennedy, 34, a scrappy Canadian graduate student with crooked glasses who is studying the impact of tobacco on air quality.He crossed the border at Buffalo on Monday morning and on Tuesday crashed the giant cigar party and trade show sponsored by the publisher of Cigar Aficionado magazine at the Marriott Marquis in Times Square.

At a Cigar Show, an Air-Quality Scientist Under Deep, Smoky Cover – New York Times

Well, what did he find? Particulate matter readings four times higher than “hazardous”. Sometimes I think of strapping on a sampler and going to the local bar just out of curiosity. I can leave the bar if it gets smoky, the bartenders and wait staff can’t. I don’t see why this is not a clear case of hazardous working conditions leading to an immediate indoor smoking ban.  but what do I know, I’m just a scientist!

Happy Thanksgiving.

    One Person's Carbon Offset – Another's Child labor?

    Byoliveridley

    The ‘carbon offset’ child labourers – Times Online

    “Pumping furiously on a foot treadle in the afternoon heat, six-year-old Sarju Ram is irrigating her impoverished family’s field, improving the crop and – without knowing it – helping environmentally sensitive holiday-makers assuage their guilt over long-haul flights to dream destinations.

    But Sarju and her four brothers and sisters working flat out in a clump of trees that provide scant shelter from the sun illustrate a growing argument over claims that British environmentalists’ efforts to curb greenhouse emissions are inadvertently fuelling an increase in child labour.”

    Carbon Offsets are a pricing mechanism setup where people can sign up to pay various companies to compensate for their greenhouse gas emissions by funding mitigation projects, such as planting trees, funding renewable energy projects, and in this case, paying money to farmers (and their families) to pump their water using a foot pump. Terrapass is one such well known company and there are many others.

    I am not so sure I would characterize this as exploitative child labor. There’s plenty of that going around in conventional manufacturing in Asia, not to mention children being used to kill. Compared to this general egregiousness, the prospect of a farmer’s kid, who would be working on the farm anyway, biking away for half an hour so his family can get some extra money does not sound all that bad. Yes, the colonialistic aspects of the story hit me in the face and makes me want to condemn a practice where a rich Westerner pays a poor farmer to pedal away for hours so she can fly to the Galapagos for a eco-vacation.

    But, in the end, these offsets do something. No, they will not do anything to slow (well, maybe a little, imperceptibly, perhaps?) CO2 emissions. Obviously, there’s no substitute to comprehensive worldwide carbon reduction strategy which prices carbon correctly, does not put barriers on technology transfer, and does not transfer greenhouse emissions from the US to Western Europe to China and India in the name of efficiency while doing nothing to ensure that that this manufacturing uses clean technology. Offsets make people aware of their actions, and choices they can make. This makes them (I hope) more likely to support major climate change legislation. It is more about attitudinal change than major change. But calling this child labor and exploitation is, I think, unwarranted.

  • Do compact fluorescent bulbs reduce mercury pollution?

    Byoliveridley

    In places that rely heavily on coal for electricity, such as West Virginia or China, the researchers say switching to CFLs can reduce mercury emissions significantly. But cleaner-powered places like California and Norway would do better to stick to incandescent bulbs when it comes to reducing mercury. “The places known for sustainability are the places that have the potential to do the most harm by bringing this technology in,” says environmental engineer Julie Zimmerman of Yale, a coauthor of the study.

    Do compact fluorescent bulbs reduce mercury pollution?.

    The good news is that in general, CFLS reduce mercury emissions significantly compared to using regular bulbs in most cases. Very unfair on CFL mercury! This works if you assume that every mg of mercury in a CFL is going to be released into the air, which is bogus. They can be, and are recycled, or they end up being landfilled, where they will not escape for a while. I’ve never broken one in many years of use. This is not a fair comparison at all, and if you have to reach to California and Norway to make a point, you’ve lost it. The reason California and Norway (more about Norway in a later blog post) are more energy efficient is because they use more energy efficient systems (like CFLs) in the first place. Therefore, they do not have to rely on coal for energy requirements. Of course, they are also lucky to have hydroelectric/geothermal sources, but they avoid coal for good reason.

    If you reduce power usage by increasing efficiency, you don’t have to build more power plants (clean or otherwise) and that is good for everyone concerned.

    Yes, the take home message is that due to the presence of a hazardous ingredient, CFLs need to be viewed as a bridge technology to LEDs. Point taken, but given that they have all those advantages over regular light bulbs, this is no bridge to nowhere!

  • Obama: Warming must be tackled now – Climate Change- msnbc.com

    Byoliveridley

    He wasn’t expected to make an appearance, let alone a splash, but President-elect Barack Obama on Tuesday delivered a videotaped message to a climate change summit convened by California Gov. Arnold Schwarzenegger, vowing quick action to curb emissions and engage in international talks.

    You can be sure that the United States will once again engage vigorously in these negotiations, and help lead the world toward a new era of global cooperation on climate change," he told hundreds of scientists, executives, governors and even foreign officials gathered in Los Angeles.

    No longer the climate outcast, is the president of the United States, that proud designation among the so called developed country leaders would now be Steven Harper.

  • Imagine a world covered with solar cells

    Byoliveridley

    it could happen soon, imagine your car parked in the sun with a plastic solar coating on the roof. Imagine every building surface generating clean electrical energy. Well, it could happen very soon (if hyperbolic sciencedaily press releases are to be believed, at any rate!).

    ScienceDaily: New Plastic Solar Cell Breaks Efficiency Record

    In order to be considered a viable technology for commercial use, solar cells must be able to convert about 8 percent of the energy in sunlight to electricity. Wake Forest researchers hope to reach 10 percent in the next year, said Carroll, who is also associate professor of physics at Wake Forest.

    Because they are flexible and easy to work with, plastic solar cells could be used as a replacement for roof tiling or home siding products or incorporated into traditional building facades. These energy harvesting devices could also be placed on automobiles. Since plastic solar cells are much lighter than the silicon solar panels structures do not have to be reinforced to support additional weight.

    Screw ethanol, put all your energy into developing solar and wind energy, battery technology and electric vehicles. See how much better an idea that is compared to corn ethanol.

    An off patent miracle cancer cure?

    Byoliveridley

    Interesting news coming out of Canada from a Dr. Anselm at the University of Alberta about a well known chemical dichloroacetic acid (like vinegar with two chlorines!).

    Cheap, safe drug kills most cancers – health – 17 January 2007 – New Scientist

    It sounds almost too good to be true: a cheap and simple drug that kills almost all cancers by switching off their “immortality”. The drug, dichloroacetate (DCA), has already been used for years to treat rare metabolic disorders and so is known to be relatively safe.

    It also has no patent, meaning it could be manufactured for a fraction of the cost of newly developed drugs.

    Here’s the PubMed citation for the article, filled with biology I will have no hope of understanding! I read the press release on sciencedaily a few days back and did a little background digging.

    A clinical trial conducted by Colombia University studying the effects of dichloroacetate on MELAs (stroke like symptoms) was halted early because everyone taking the medication showed significant effects of neural toxicity. This study was commented on by Dr. Anselm who theorized that the effect could be caused by a specific gene mutation not seen in a lot of the patients he works with.

    So, there is some reason for caution on this wonder drug, it may be toxic at certain doses to certain people. Most chemotherapetic drugs are horrendously toxic too. But if this is not a concern, Dr Anselm, meet Sunil Shaunak and his wonderful proposal to setup an alternative pipeline for drug approval that does not involve big/small pharma. I Am sure between Bill Gates, or George Soros, a few million bucks can be rustled up for a cancer cure.

  • BC's Election

    Byoliveridley

    Is over and the centre-right Liberals won. Many in the traditional environmental movement are trumpeting it as a referendum on the BC Carbon Tax. I am not so sure. The so called people who were supposed to vote for the opposition left leaning NDP, but did not because of their (admittedly stupid) opposition to the “gas tax” also gave the Green Party their lowest share of the vote in the last few years. I am finding it hard to imagine a left leaning voter voting for the Liberals instead of the NDP, rather than throwing her vote on the Green Party.

    The truth is probably a lot simpler. Carole James of the NDP did not resonate with voters as an alternative for many reasons, poor campaign positioning, lack of vision, poor media coverage, etc. and in tough economic times, BC just made what it considered a safe choice.

    Of course, BC also made a “safe” choice and rejected a proportional representation system for the province. More will be known once any exit poll data is released, but a proposal which came within a couple of percentage points of passing in the last election failed roundly this time. There is early speculation that it was how the question was asked. I would have preferred a multi-party proportional system to reduce the stranglehold of the two major parties and get some Green Party representation in the legislature.

    Anyway, full speed ahead for BC’s puny Carbon Tax, which will go all the way to $30 a ton in a couple of years, let’s see what that does to compensate for The Liberal’s penchant for massive road building, offshore drilling ideas and “business friendly” privatization of the commons approach to governance.
