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.

House mulls bill on food label removal – Boston.com:

“This bill would strip state governments of the ability to protect their residents through state laws and regulations relating to the safety of food and food packaging,” the attorneys general wrote.

The obvious target, they said, is California’s Proposition 65, a law passed by voters requiring companies to warn the public of potentially dangerous toxins in food. The law has prompted California to file lawsuits seeking an array of warnings, including the mercury content in canned tuna and the presence of lead in Mexican candy.

Prop 65 is a California Law that requires the state of California to “publish, at least annually, a list of chemicals known to the state to cause cancer or reproductive toxicity” and for businesses to post warning labels. Well naturally, it kinda depresses sales of canned tuna if you have mercury warnings on the labels, mmm, lead in my candy, so delicious…

This is obviously not good for the consumer, I undestand that businesses feel the burden of extra labeling, depressed sales, etc, but why should the onus always be on the consumer? If the assumption that it is the consumer’s responsibility to find out that there is mercury in his/her tuna and that the informed consumer will make informed choices, why not make it easier on the consumer to find out and then rely on him/her to make that choice? What are the companies afraid of, exactly?

Cleaner Air Brings Drop in Death Rate – New York Times

When air pollution in a city declines, the city benefits with a directly proportional drop in death rates, a new study has found.

In other news, Dog bites man (I have never typed “dog bites man” into google news before – shocking…)

Well, the Dockery and company published a seminal set of articles on the 6 city study back in the 90s that are the gold standard of air pollution epidemiology. It takes large long-term studies like these to establish even tenuous correlations, and their graphs connecting particle concentrations and mortality were beautiful straight lines.

This follow up is pretty cool because the cities had made most of the reductions in the 70s and 80s after the passage of the Clean Air Act and this study clearly demonstrates that the bar for lowering mortality/cancer rates by lowering fine particle levels has not been reached yet. The abstract of the paper is below the fold.

In response to a stupid “global warming sceptics”, scientists waste their precious time to prove the obvious all over again.

BBC NEWS | UK | ‘No sun link’ to climate change

Dr Lockwood initiated the study partially in response to the TV documentary The Great Global Warming Swindle, broadcast on Britain’s Channel Four earlier this year, which featured the cosmic ray hypothesis.

“All the graphs they showed stopped in about 1980, and I knew why, because things diverged after that,” he told the BBC News website.

“You can’t just ignore bits of data that you don’t like,” he said.

The grist features a must read post on endocrine disruption (ED). Great first paragraph, BTW, but read the whole thing. Before Viagra, had any one other than doctors and the unfortunate masses suffering such dysfunction ever heard of erectile dysfunction? The effects of direct to consumer drug marketing of diseases and disorders is the subject of other posts, but this one’s about endocrine disruptors!

Side note, Erectile dysfunction has 2.3 million hits in google, Endocrine Disruption (or disruptors) has 1.7 million, so, at least google is catching up!

The ED you should really be worried about: Endocrine disruption | Gristmill: The environmental news blog | Grist

What a crazy world we live in when almost everyone knows what the acronym ED stands for. Millions of dollars have been poured into creating awareness of ED, erectile dysfunction, because it is profitable. This 21st-century sales-pitch strategy — “disease mongering” — has proven to be good for the bottom line. The irony of all this is that there is another ED out there into which millions have also been poured — to keep it a secret. That ED is endocrine disruption, and if the public were to learn about it, bottom lines could shrink instead of grow.

Endocrine disruption should be right at the top of the list of most critical technological disasters facing the world today, up with climate change. With little notice, vast volumes and combinations of synthetic chemicals have settled in every environment in the world, including the womb environment. Synthetic chemicals at very low concentrations in the womb change how genes are programmed, cells develop, tissues form, and organs function, and thus undermine the potential and survival of developing animals, including humans. The chemicals threatening the integrity of future generations are derived from the processing of crude oil and natural gas, the same processes that are driving climate change. This is an integral part of the climate change story.
