Arsenic a rising risk?

This is new information? Tell that to the millions of Bangladeshis and Indians suffering from Arsenic for many years now.

As groundwater use increases due to population pressure and overexploitation of freshwater, expect this problem to get worse.

Arsenic in Drinking Water Said to Be Rising Risk – New York Times

Naturally occurring arsenic in drinking water poses a growing global health risk as large numbers of people unknowingly consume unsafe levels, researchers said on Wednesday.

The problem is bigger than scientists had thought, and it affects nearly 140 million people in more than 70 countries, according to new research presented at the annual Royal Geographical Society meeting in London.

  • Volcanos and Climate Geoengineering

    The first thing that occurred to me when I heard about the Sarychev eruption was whether it was going to be large enough to inject significant quantities of sulphate aerosol into the stratosphere. Apparently, it is.

    Sarychev Eruption Generates Large Cloud of Sulfur Dioxide

    When sulfur dioxide reacts with water vapor, it creates sulfate ions (the precursors to sulfuric acid), which are very reflective. Powerful volcanic eruptions can inject sulfate aerosols into the stratosphere, beyond the reach of cleansing rainfall. At these altitudes, the sulfates can linger for months or years, cooling the climate by reflecting incoming sunlight. (The effect is stronger when the eruptions occur at tropical latitudes.) Carn says the persistence of such high concentrations of sulfur dioxide in the OMI data throughout the week indicates that the plume from Sarychev Peak reached high altitudes. Data from other satellites (such as CALIPSO) suggest that the volcanic plume reached altitudes of 10–15 kilometers, and perhaps as high as 21 kilometers.

    In 1991, the eruption of Mount Pinatubo in the Philippines injected enough sulphate into the atmosphere to cause a 0.5° C drop in global temperature. This was caused by about 20 million tonnes of SO2. We are nowhere close to these kind of emission levels. After all, Pinatubo was one of the two biggest volcanic events of the century.

    Injecting sulphate particles into the stratosphere has been proposed for a while now, I first wrote about it in 2006 when a prominent atmospheric chemist, Paul Crutzen wrote an article proposing this. The science behind this proposal is basic, sulphate aerosols of the size that would be formed from the oxidation of SO2 are the right size to scatter and reflect solar radiation back into space (my Masters thesis did a first order estimate of this effect from Indian emissions!). If injected directly into the stratosphere, they can stay there for a long time and will not deposit to the the Earth’s surface as acid rain. The issue is managing all the crazy regional variations in climate that would result, and the attendant complications in assigning blame, etc. It would also not help the oceans, which would acidify to hell with all the CO2.

    Anyway, so much for that, the volcano is causing all kinds of havoc with Pacific travel and making for all kinds of cool pictures, which are about the most interesting thing happening at this point in time. We shall see how the sulphate situation plays out in the days to come when the dust settles.

    Melamine – now in Pigs

    The pet food recall gets scarier. The FDA does not have this issue under control. It is not a conspiracy to hide anything, it’s just the pace at which the FDA operates, and its lack of mandate to really regulate animal feed.

    Pet Foods May Have Been Intentionally Poisoned

    The FDA and Agriculture Department also were investigating whether some pet food made by one of the five companies supplied by Wilbur-Ellis was diverted for use as hog feed after it was found unsuitable for pet consumption.

    “We understand it did make it into some hog feed and we are following up on that as well,” Sundlof said.

    Later Thursday, California officials said they believe the melamine at the quarantined hog farm came from rice protein concentrate imported from China by Diamond Pet Food’s Lathrop facility, which produces products under the Natural Balance brand and sold salvage pet food to the farm for pig feed.

    “Although all animals appear healthy, we are taking this action out of an abundance of caution,” State Veterinarian Richard Breitmeyer said in a statement. “It is unknown if the chemical will be detected in meat.”

    Officials are investigating American Hog Farm’s sales records to determine who may be affected by the quarantine, said Steve Lyle, a spokesman for the California Department of Food and Agriculture. The 1,500-animal farm operates as a “custom slaughterhouse,” which means it generally does not supply meat to commercial outlets.

    “Mostly it is not so-called mainstream pork. This is an operation that sells to folks who come in and want a whole pig,” said Lyle said.

    Officials urged those who purchased pigs from American Hog Farm since April 3 to not consume the

    Well, the issue is not the safety of the melamine contaminated pork, the risk to humans is possibly low. The problem is that these ingredients are out of control, and unaccounted for, and being diverted to places they should not be. The systemic flaws are many, and I hope the FDA will issue some new guidelines to tighten up animal feed standards.

    Another tidbit:

    FDA officials would not release the names of the other two manufacturers that Wilbur-Ellis supplied, citing its ongoing investigation

    Is it just me, or does this always happen on a Friday???

  • Liquid Coal – Flooding back to life!

    See, it was only a matter of time before liquid coal made its egregious way back to front and center of the “energy security” debate.

    Lawmakers Push for Big Subsidies for Coal Process – New York Times

    Prodded by intense lobbying from the coal industry, lawmakers from coal states are proposing that taxpayers guarantee billions of dollars in construction loans for coal-to-liquid production plants, guarantee minimum prices for the new fuel, and guarantee big government purchases for the next 25 years.

    Liquid coal produces more CO2 than gasoline, so, all the coal makers are claiming that they will sequester the CO2, and use renewable energy to produce the coal, it’s a lie, and an expensive one at that.

    It is going to be more expensive, more polluting, and more profitable for big coal companies at tax payers expense than any other options available.

    In addition to construction loan guarantees, Mr. Boucher would
    protect the first six liquid plants from drops in energy prices. If oil
    prices fell below about $40 a barrel, the government would
    automatically grant loans to the first six plants that make coal-based
    fuels. If oil prices climbed to $80 a barrel, companies would have to
    pay a surcharge to the government.

    But the most important guarantee, many coal producers said, is the prospect of signing 25-year purchase contracts with the Air Force.

    Wow, why can’t solar or wind energy get these kinds of incentives?

    “There is financial uncertainty, which is inhibiting the flow of
    private capital into the construction of coal-to-liquid facilities,”
    said Mr. Boucher, who supports most of the proposals and is drafting
    portions of the energy bill.

    Yes, there is “financial uncertainty” because without the taxation of the American public, there is no hope of making money with this thing. It’s just a giant boondoggle to transfer money from the public sphere into coal companies.

    The US is losing its collective mind!

  • White House Refused to Open Pollutants E-Mail

    The White House in December refused to accept the Environmental Protection Agency’s conclusion that greenhouse gases are pollutants that must be controlled, telling agency officials that an e-mail message containing the document would not be opened, senior E.P.A. officials said last week.

  • Corn Can't Solve Our Problem – washingtonpost.com

    A must read for anyone who likes articulate scientists writing very approachable articles about important subjects!
    Corn Can’t Solve Our Problem – washingtonpost.com

    If every one of the 70 million acres on which corn was grown in 2006 was used for ethanol, the amount produced would displace only 12 percent of the U.S. gasoline market. Moreover, the “new” (non-fossil) energy gained would be very small — just 2.4 percent of the market. Car tune-ups and proper tire air pressure would save more energy.

    Proper tire pressure is not sexy, and does not lead to billions of dollars of profits!

    The net effect is that ethanol from corn grown in the Corn Belt does increase atmospheric greenhouse gases, and this increase is only about 15 percent less than the increase caused by an equivalent amount of gasoline

    Corn is such a boondongle, it’s amazing what the ADMs and Monsantos of the world can do.

    This means that when tropical woodland is cleared to produce sugar cane for ethanol, the greenhouse gas released is about 50 percent greater than what occurs from the production and use of the same amount of gasoline. And that statistic holds for at least two decades.

    Brazil will not solve all your problems (unless they’re samba related!). Increased demand for ethanol from Brazil could lead to clearcutting of the rain forest/other fallow grassland.

    Across the full process of growing high-diversity prairie hay, converting it into an energy source and using that energy, we found a net removal and storage of about a ton and a half of atmospheric carbon dioxide per acre. The net effect is that ethanol or synthetic gasoline produced from this grass on degraded land can provide energy that actually reduces atmospheric levels of carbon dioxide.

    It’s a very well written article.
