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.

  • Conflicts of Interest in Bisphenol A Decision Making

    I have written about bisphenol A recently. It’s a chemical found in polycarbonate plastics that has been linked with some crazy effects in mice at ambient levels including disruption of oogenesis (egg production) and effects two generations removed (grandmother effects).

    Public health agency linked to chemical industry – Los Angeles Times

    For nearly a decade, a federal agency has been responsible for assessing the dangers that chemicals pose to reproductive health. But much of the agency’s work has been conducted by a private consulting company that has close ties to the chemical industry, including manufacturers of a compound in plastics that has been linked to reproductive damage.

    In 1998, the Center for the Evaluation of Risks to Human Reproduction was established within the National Institutes of Health to assess the dangers of chemicals and help determine which ones should be regulated. Sciences International, an Alexandria, Va., consulting firm that has been funded by more than 50 industrial companies, has played a key role in the center’s activities, reviewing the risks of chemicals, preparing reports, and helping select members of its scientific review panel and setting their agendas, according to government and company documents.

    This kind of work is too important to be left to contractors like Sciences International (however good they may be), which also has contracts with companies that manufacture and market products containing Bisphenol A. It’s very simple, most companies, for profit entities and even non-profits dependent on funding sources tend to maximize short term gain over long term good. While the political arm of the government does that as well, the institutions stable enough to do reliable work on policy issues that affect our long term well being are few in number. Government run research with stable funding, good employees and good management will do this work well, it’s a good match between the nature of the work and the nature of the organizations.

    The ever excellent Pump Handle has more, I read their post as I was writing this one and so, nothing more to say, really, except, remember Children of Men! Fertility is not to be toyed with, any chemical that has the ability to affect egg production two generations down needs to be handled with care. 

  • Benzene in Soft Drinks – Analytical Artifact?

    An update on the benzene story from last month.

    Chemical & Engineering News: Latest News – Dispute Over Benzene In Drinks

    In late 2005, FDA began analyzing beverages containing benzoate and ascorbic acid. The majority of samples contained either no detectable benzene or levels below 5 ppb, says Robert E. Brackett, director of FDA’s Center for Food Safety & Applied Nutrition. FDA’s results are preliminary. After its survey is complete, the agency will determine what, if any, additional action is necessary, Brackett wrote to EWG. Changes in FDA’s analytical procedures may account for the differences in results. To collect benzene in the earlier tests, FDA used a purge-and-trap method, in which the samples were heated to 100 °C for 30 minutes. Recently, the agency has been using a static-headspace methodology, which does not involve much heat. In the earlier tests, the high heat was probably creating benzene, says an FDA source who asked not to be identified.

    The explanation seems to make sense. Low level analysis is riddled with instances such as these, where the analyte you’re looking for is  introduced into the sample after the fact. It is impossible to decide without looking at the protocol whether this happened or not. Since the source of the benzene is from the reaction of ascorbic acid (aka Vitamin C) and benzoate salts, notably sodium benzoate, it would have been clear to anyone doing the analysis to avoid conditions that would result in the formation of benzene during the analysis, or maybe not…

    Static Headspace analysis usually involves some heating as well, at much lower temperatures for shorter periods of time, though in the case of something as hydrophobic as benzene, not much heat would be required. So, the artifacts in static headspace would in this case be lower than in purge and trap analysis.

    Still not a concern in the grand scheme of aggregate benzene exposure.

  • Oil Sands work even with carbon pricing

    More on this later, but according to this lifecycle analysis, oil produced from the oil sands of Alberta can be cost competitive with crude oil even if carbon costs are taken into account.

    However, ramp up of production will lead to very high water usage and massive local and regional impacts.

    In other words, Alberta, you’re screwed, rest of the world, you’ll die at the same rate!

    Opinion Polls and Yes Prime Minister

    This story from the grist about a push poll arranged by Rasmussen showing 67% support for the reinstatement of offshore oil drilling in the United States reminded me of this most delightful exchange from Yes Prime Minister, still one of my all time favourite television shows and one that taught me almost everything I needed to know about parliamentary politics at a tender age. The show is about British politics through the eyes of an earnest but bumbling politician, his very experienced bureaucratic handler and his secretary with divided loyalties. The show is incredibly insightful and funny at the same time. But, before I get to my favourite part, some background…

    It’s that time of the year when the republicans want to enrich their oil buddies by opening up oil drilling offshore of the U.S. This year, the high price of gas provides a convenient excuse and rallying point. After all, who wouldn’t want to pay less for gas. Of course, a U.S government study done by the Energy Information Administration in 2007 indicates that at best, you would see a 3% increase in production by 2030, and we all know how much that would affect gasoline prices this summer. Yet, here’s the first question from the “poll”

    In order to reduce the price of gas, should drilling be allowed in offshore oil wells off the coasts of California, Florida, and other states

    No really, what are you supposed to say? Can such reputable firms lie to you like that? Anyway, Joseph Romm from the original gristmill post breaks it down completely so I don’t have to. but after reading his post, come back and read the following exchange from Yes Prime Minister, and do listen to the actual audio clip from the show.

    Yes Prime Minister – Season 1Episode 2 (warning: Strangely formatted website)

    Sir Humphrey: “You know what happens: nice young lady comes up to you. Obviously you want to create a good impression, you don’t want to look a fool, do you? So she starts asking you some questions: Mr. Woolley, are you worried about the number of young people without jobs?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Are you worried about the rise in crime among teenagers?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Do you think there is a lack of discipline in our Comprehensive schools?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Do you think young people welcome some authority and leadership in their lives?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Do you think they respond to a challenge?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Would you be in favour of reintroducing National Service?”

    Bernard Woolley: “Oh…well, I suppose I might be.”

    Sir Humphrey: “Yes or no?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Of course you would, Bernard. After all you told you can’t say no to that. So they don’t mention the first five questions and they publish the last one.”

    Bernard Woolley: “Is that really what they do?”

    Sir Humphrey: “Well, not the reputable ones no, but there aren’t many of those. So alternatively the young lady can get the opposite result.”

    Bernard Woolley: “How?”

    Sir Humphrey: “Mr. Woolley, are you worried about the danger of war?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Are you worried about the growth of armaments?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Do you think there is a danger in giving young people guns and teaching them how to kill?”

    Bernard Woolley: “Yes”Sir Humphrey: “Do you think it is wrong to force people to take up arms against their will?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “Would you oppose the reintroduction of National Service?”

    Bernard Woolley: “Yes”

    Sir Humphrey: “There you are, you see Bernard. The perfect balanced sample.”

    That is what I think about opinion polls!

  • American Idiot

    But Mr. Peterson, when asked by reporters Tuesday about the report’s findings, said they run counter to what many in his region are experiencing

    “We’ve just had the biggest floods and coldest winters we’ve ever had,” he said. “They’re saying to us [that climate change is] going to be a big problem because it’s going to be warmer than it usually is; my farmers are going to say that’s a good thing since they’ll be able to grow more corn.”

    Farm Belt Lawmakers Challenge Climate Bill – WSJ.com

    So, it appears that every party in power South of the Border needs an influential legislator making ridiculous statements deliberately confusing weather and climate to derail even the weak sauce that is passing through the US congress right now.

    Millions of people are in the process of becoming climate refugees while this “Corn”gressman and his big agriculture cronies dither, lie and weaken climate change action.

    At what point in time does deliberate obstruction of action that will save lives and homes become sabotage and assault?

  • Liquid Coal – Temporarily Frozen

    Liquid coal is back in the news (at least my news!). Via the excellent Grist, Jon Tester (D-Montana – think coal!) casts a principled vote to kill an amendment that would have “mandated” a certain amount of liquid coal be used as part of an omnibus energy package bill.

    Panel rejects coal amendment

    Thomas accused Tester and other Democrats of failing to act on their words of praise for transportation fuels made from coal. But Tester said he couldn’t support the amendment because it would have scuttled the entire bill to which it was attached.

    Tester voted against the provision during a meeting of the Senate Energy and Natural Resources Committee to assemble an energy package. The legislation contains measures boosting biofuels, energy efficiency and research and development on carbon capture and storage technology.

    Thomas’s amendment would have required 21 billion gallons of coal-based fuels to be used annually by 2022. The bill already had a provision mandating 36 billion gallons of biofuels by 2022. The amendment was defeated on a 12-11 party-line vote.

    The Democratic and Republican heads of the Energy Committee had tried to prevent the coal-to-liquids issue from coming up during the panel’s meeting. They wanted to pass a bill out of committee easily and deal with contentious issues, including that one, during debate on the Senate floor

    With such powerful friends, this amendment will not go away. Expect it to be brought back on to the senate floor when it leaves committee. The coal senators of Illinois, West Virginia, Kentucky and the mountain west love the money this will bring to their states. They can pretend to look away from all the devastating effects of coal mining, and the CO2 emissions, etc. by invoking “energy security”. I give you senator Craig Thomas (R-Coal):

    “The bill we’re talking about of course does not include coal and the new opportunities to change the process for developing coal, which would not only enhance our security but it would also reduce and help with the global warming situation,” Thomas said. “I really think if we don’t deal with one of our most abundant resources then we fail to deal with energy security.”

    Yes, using liquid coal will “reduce and help with the global warming situation”. I mean, can’t you at least come up with a plausible half-truth?

    Liquid coal produces more CO2 than gasoline, so how will it help with the global warming situation? Seriously…
