New York Odor from the Marshes?

Byoliveridley

Turns out that the fugitive emission of nasty sulfur gases in New York that had Fox News suspecting terrorism for a while may have come from more mundane sources.

Sniffing Out the Truth – New York Times

But we haven’t, and we think we can support one of the theories of the odor’s source that has been suggested. Based on our familiarity with the local aquatic environment and regional meteorology, we believe that the odor was caused by gases released from saltwater marshes in the metropolitan area. Let us explain. The intertidal sediments in this region are home to micro-organisms that produce sulfur compounds. When these sediments interact with saltwater that contains low levels of oxygen, gases are released. These gases include hydrogen sulfide and a variety of thiols (like the gas additives thiophane and mercaptan) — all of which have an odor similar to rotten eggs.

First, there was a low tide in the coastal marshes from roughly 4 a.m. to 6 a.m. Second, we experienced winds from the south and an atmospheric inversion, which created something like a low-lying bubble of air.

The result of the two factors? The low tide exposed the marsh sediments and hastened the release of sulfur gases into the atmosphere. The inversion trapped the odor close to the groundand the southerly winds then carried it to Lower Manhattan, where it remained until atmospheric conditions changed.

Damn, this is CSI NY (Atmospheric Chemistry and Modeling Division), good stuff!

Our explanation highlights the consequences of excessive nutrient loading and the resulting low oxygen levels in local coastal waters. (By nutrient loading, we mean exposing water to sewage, fertilizer, chemicals or other pollutants.) Of course, these consequences go beyond odor — they kill marsh vegetation, degrade the wider marine habitat and make it unsafe to swim or fish.

Indeed, so the cause, while natural is not really natural, it is from untreated sewage. New Yorkers, stop blaming New Jersey! Look at yourself!

    Environmental Racism, Global Warming Edition

    Byoliveridley

    As armchair critics debate endlessly on the virtues and vices of carbon trading versus carbon taxes, they are in no danger of losing their armchairs (or their homes, or their money, or their livelihood). Africa and Asia, not so lucky.

    Poor Nations to Bear Brunt as World Warms – New York Times

    Two-thirds of the atmospheric buildup of carbon dioxide, a heat-trapping greenhouse gas that can persist in the air for centuries, has come in nearly equal proportions from the United States and Western European countries. Those and other wealthy nations are investing in windmill-powered plants that turn seawater to drinking water, in flood barriers and floatable homes, and in grains and soybeans genetically altered to flourish even in a drought. In contrast, Africa accounts for less than 3 percent of the global emissions of carbon dioxide from fuel burning since 1900, yet its 840 million people face some of the biggest risks from drought and disrupted water supplies, according to new scientific assessments. As the oceans swell with water from melting ice sheets, it is the crowded river deltas in southern Asia and Egypt, along with small island nations, that are most at risk.

    I read another story about Bangladesh recently, apparently in Bangladesh, there will be both flooding and drought due to cimate change!

    We are fighting climate change on the front line,” Professor Nishat
    told The Independent earlier this year. “But the battle has to be
    integrated across all countries.”

    Bangladesh has good reason to feel aggrieved at global warming. Its
    annual carbon emissions only 0.172 tons per capita, compared to 21 tons
    in the US.

    If the rivers dry up, it would leave Bangladesh completely at the mercy of the rains.

    What is to be done? There are no simple answers, but this is a global issue that requires a global solution. There needs to be a relentless push for efficiency and conservation, with technologies being made available sans intellectual property and patent protection to help India and China control emissions. Efficiency is where the low hanging fruit are. This wikipedia article is a decent compendium of options.

    Europe has started on the control path already. The U.S has to act, will it do anything this year? Or do we have to wait for this? I am very cynical about the West’s ability and willingness to act in this regard. When the prime contributors and benefiters of a harmful action are not the same as the ones who will face the worst consequences, where’s the will? As life in the third world becomes more miserable, the rich countries can always build more walls.

    No fun and games here!

    Could not get any clearer than this.

    ScienceDaily: Study Verifies More Hazardous Waste Facilities Located In Minority Areas

    The other side of that argument is that the hazardous waste facilities came first, which causes the neighborhood demographics to change. As that argument goes, the more affluent white people move out, and poorer minority people are forced to stay or move in, said Paul Mohai, a professor in the U-M School of Natural Resources and Environment. However, done in collaboration with Robin Saha, a former U-M PhD student and post-doctoral scholar, now an assistant professor at University of Montana, shows that minorities were living in the areas where hazardous waste facilities decided to locate before the facilities arrived. Their study also shows that the demographics in the neighborhoods were already changing and that white residents had already started to move out when the facility was sited. “What we discovered is that there are demographic changes after the siting but they started before the siting,” Mohai said. “Our argument is that what’s likely happening is the area is going through a demographic shift, and it lowers the social capital and political clout of the neighborhood so it becomes the path of least resistance.”

    This is not just about the money. Over and above social capital and political clout, it seems that race trumps all.

    Using the new method, researchers have found that racial disparities in the location of hazardous waste facilities are much greater than previous studies have shown. Furthermore, the disparities persist even when controlling for economic and sociopolitical variables, suggesting that racial targeting, housing discrimination and other factors uniquely associated with race influence the location of the nations’ hazardous waste facilities.

    Depressing.

    Fishing Major threat to Turtles

    Byoliveridley

    Well, not the least bit surprising, sea turtles have always been very difficult to track, and we’re finally getting verification that, gasp, turtles’ lives cannot be described in simple juvenile = open sea, adult = coast behavior.

    BBC NEWS | Science/Nature | Fishing ‘major threat’ to turtles

    Until now scientists have believed that young turtles live in the open ocean, but change to a coastal habitat when they reach a certain size.

    But researchers working in Cape Verde found that most adults nesting there retain their open water behaviour, with the attendant risk posed by longline boats.

    “The bottom line is that we thought juveniles experienced this risk out in the open ocean with longline fisheries,” said Brendan Godley from the University of Exeter.

    “We thought that if you got them past that, then unless they’re being taken by inshore fisheries, you’re OK,” he told the BBC News website.

    “But now you’ve got adults exposed to longline fisheries, which is very worrying.”

  • Recycling Paper

    Byoliveridley

    recycle.gifNow you’re having this conversation over dinner about recycling (yes, I have had this conversation before with lots of people), and there pipes up this voice which says “Well, I read somewhere that it costs more money to recycle than to just throw it away”, and you think, “waitaminnit, that can’t be right, but where’s the proof?” Well, at least for paper, here it is, and bless the EU for taking the trouble (I read about this in the Environmental Valuation and Cost-Benefit News Blog).

    Lifecycle Analysis and Cost Benefit Analysis on Paper Recycling

    No, I did not read all 160 pages, but sure did read the Executive Summary…

    The LCA review concludes that the majority of LCAs indicate that recycling of paper has lower environmental impacts than the alternative options of landfill and incineration. The result is very clear in the comparison of recycling with landfilling, and less pronounced, but still clear, in the comparison of recycling with incineration. The CBA review concludes that in little more than half of the CBAs, paper recycling has higher socioeconomic benefits than other management options. In the remainder of the studies, the socio-economic benefits of incineration, landfill or other options are higher than those gained from recycling. It is often said that CBAs are generally favourable to other waste management options than recycling. However due to the heterogeneity of the methodologies used in the reviewed CBAs, it is not possible to confirm or to reject this statement.

    They looked at 9 different regions and did an LCA and CBA for each. Apparently, and I did not know this, the LCA evaluation system is well standardized and codified, so it is easy to compare results between regions, but the CBA mechanisms are not as well codified, hence more sensitive to the assumptions made.

    Fascinating reading aside, the answer is clear, recycle your paper! At least they make it easy in Chapel Hill.

    How NAFTA infringes on local environmental regulations

    Byoliveridley

    Dow AgroSciences is considering using the controversial investor-protection provisions of the North American free-trade agreement to seek compensation from the federal government over Quebec's ban on the cosmetic use of pesticides.

    The company, a maker of the weed-killer 2,4-D, filed a notice of intent to submit a claim to arbitration under NAFTA in late August. The 27-page legal action was posted yesterday on the Foreign Affairs website, where it is listed as a dispute to which Canada is a party.

    via globeandmail.com: Ban on pesticides may face NAFTA test

    Here is Sierra Club’s assessment of 2,4-D. It is not as bad as, say, DDT, but not something an average householder would ever need to use. Limiting use and exposure is in everyone’s best interest except Dow’s, which is why they have filed this lawsuit.

    I would say it infringes on a province’s right to set strict health and safety standards for its people, but if we accept that corporations have more rights than people, we would expect this kind of lawsuit to happen with more frequency.

    Note that a much more egregious actor, lindane, which was deregistered by even the Bush EPA is subject of a similar challenge in Canada, and Bisphenol A is probably next.

    Can’t blame the companies for exploiting loopholes (that they no doubt inserted, of course), but it seems that countries should always have the right to enforce stricter standards if they so desire.

    Hog Factories are Evil Part 1232

    Byoliveridley

    This rather interesting study tracks the movement and evolution of antibiotic resistance from hog cesspools (lagoons) caused by factory production (hog farming) of pig meat. You see, in order to pack that many hogs together and not cause them to keel over and die from disease, they have to be pumped full of antibiotics. Guess where the antibiotics end up? In their “refuse”.

    As always, I leave you with The Meatrix if you want to know more about factory farming.

    Antibiotic Resistance Tracked From Hog Farms to Groundwater

    The routine use of antibiotics in swine production can have unintended consequences, with antibiotic resistance genes sometimes leaking from waste lagoons into groundwater, according to new research from the University of Illinois.

    Researchers report that some genes found in hog waste lagoons are transferred, “like batons,” from one bacterial species to another. This migration across species and into new environments sometimes dilutes, and sometimes amplifies, genes conferring antibiotic resistance, they say.

    The new report, in the August issue of “Applied and Environmental Microbiology,” tracks the passage of tetracycline resistance genes from hog waste lagoons into groundwater wells at two Illinois swine facilities.

    Tetracycline is widely used in swine production. It is injected into the animals to treat or prevent disease, and is often used as an additive in hog feed to boost the animals’ growth.

    Its near-continuous use in some hog farms promotes the evolution of tetracycline-resistant strains in the animals’ digestive tracts and manure.

    This is the first study to take a broad sample of tetracycline resistance genes in a landscape dominated by hog farming, said principal investigator R.I. Mackie, a professor in the University of Illinois-Champaign department of animal sciences and an affiliate of the Institute for Genomic Biology.
