Hogwash!!!

Boy, it’s all arsenic all the time on this blog!

Chemical & Engineering News: Latest News – In Katrina’s Wake, An Arsenic Threat

An incredible 72 million m³ of debris was created when Hurricane Katrina wreaked havoc in Louisiana and Mississippi in 2005. A survey of this debris now reveals that an estimated 1,740 metric tons of arsenic could leach into groundwater from unlined landfills where the materials are being disposed (Environ. Sci. Technol., DOI: 10.1021/es0622812).

Here’s EPA’s page on arsenic treated wood, and here’s the cheerleader page for same (mmm, industry advocacy websites, delicious!). Note that the EPA is currently working with the manufacturers to “voluntarily” phase out the use of Chromated Copper Arsenate in residential settings. Note that there are several alternatives available, all of them less toxic and equally effective. While this “voluntary” action limits direct exposure for certain types of people, old wood ending up in unlined landfills will overwhelmingly affect people who live near said landfills, namely the poor, and African American. 

Even lined landfills leak eventually, and while other organic matter may degrade before the leaking, arsenic and heavy metals are not going anywhere. Unlined landfills, which is a fancy way of saying hole in the ground where you throw trash in, are completely unacceptable in this day and age in a so called developed country like the US of A. On the other hand, it is fashionable to refer to Louisiana as a third world country, so I guess anything goes for those kinds of people, eh.

Read both these stories and go bang your head on a wall repeatedly.

Europe creates attractive clean energy scene – International Herald Tribune

But a commitment by European governments to budding clean-energy entrepreneurs is creating a more welcoming environment than in America, where erratic support and onerous financial rules have given pause to some start-ups and investors.

American ‘Coal Rush’ Hits Some Hurdles

The nation’s demand for electricity is growing, and utilities want to build new power plants to satisfy that appetite. Most of those plants — perhaps as many as 150 — would burn coal.

Well, at least the coal rush is hitting a few hurdles. But even if half those plants don’t come about, that’s still 70+ coal fired power plants, nice!

The interesting part of the IHT story to me was this.

Venture capitalists and private equity investors in North America have been more bullish, providing $3.5 billion to clean-energy developers in 2006, roughly triple the amount raised in Europe, the Middle East and Africa, according to New Energy Finance, a research firm based in London.

So, if the US had the right incentives, Americans would be investing there, creating jobs there, improving infrastructure there instead of in Europe. I guess those very “patriotic” American lawmakers don’t think that far ahead. Note also that all the tax cuts to wealthy Americans leaves a lot of cash floating around for them to invest in projects in other parts of the world. These are investments the US won’t reap a benefit on as a country, or create jobs for the working proletariat – Nice tax cuts, more patriotism, I guess. Such a poor return on investment on these tax cuts.

Who said CDs were dead, this is, hands down, the coolest paper on screening techniques I have seen in a while. I haven’t seen the rest of the paper, not Open Access, of course, but the abstract does make it sound cool.

Microimmunoanalysis on Standard Compact Discs To Determine Low Abundant Compounds

“High-density competitive indirect microimmunoassays were performed in both sides of compact discs by direct absorption of immunoreagents on polycarbonate surface, using gold- or enzyme-labeled immunoglobulins as tracers for displaying the immunoreaction. The operational principle is based on the use of a low-reflectivity compact disc as analytical platform that allows the reflection/transmission (30/70%) of the CD reader laser beam ( 780 nm). The reflected light is used to scan the disc track keeping it in movement. The transmitted light is detected by a planar photodiode integrated on the CD drive. The variation of the optical transmission of the light caused by the immunoreaction products is related to the sample concentration. As a proof of concept, low abundant compounds, commonly used as pesticides, were detected in a 60-min total assay time, with a limit of detection ranging from 0.02 to 0.62 ug/L for 2,4,5-TP, chlorpyriphos, and metolachlor. The obtained results show the enormous prospective of compact discs in combination with CD players for multiresidue and drug discovery applications.”

Why are techniques like these important in the world of environmental analysis? Because they change the paradigm from laboratory based techniques to field based analysis. You don’t have to take a bunch of samples, spend a lot of time and money shipping them to a lab and waiting for the results. You can pop your samples into a CD player and one hour later (less than a 74 minute listening time on a CD!), you’ll have results.

Awesome stuff, I’d love to see it in action, or even try to replicate the work. It looks like you have to make some modifications to the player to make it work, but hey, there are millions of CD players that are going to be obsoleted in the next few years.

The battle for Quebec in the federal election campaign heated up on Thursday with Conservative Leader Stephen Harper telling a Montreal audience that Liberal Leader Stéphane Dion's carbon tax proposal threatens Canada's national unity.

"The carbon tax will do more than undermine the economy," Harper said to a crowd of business leaders. "By undermining the economy and by re-centralizing money and power in Ottawa, it can only undermine the progress we have been making on national unity."

CBC.ca – Canada Votes – Dion’s Green Shift threatens national unity: Harper.
Mr. Harper is calling for disaster if there’s any kind of serious carbon dioxide mitigation plan. His party’s plan, as I mentioned a few days back, is pretty toothless, and his attitude does not bode well for climate change mitigation policy in Canada.
