Smell manure?

FEED – May 2006

Congress may exempt factory farms from pollution laws Large agribusiness companies are pushing their friends in Congress to exempt factory farms from the pollution reporting and cleanup provisions in key pollution laws. The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, also known as Superfund) and the Emergency Planning and Community Right to Know Act (EPCRA) provide an essential safety net for protecting water supplies from livestock pollution and for providing warnings of toxic air emissions from factory farms. Over 140 representatives are supporting a bill, H.R. 4341, that would give this sweetheart deal to factory farms. The bill may soon be attached to a “must-pass” spending bill in an effort to speed this ill-conceived measure through Congress. Please call your representative and urge him or her to oppose this dangerous legislation. To learn more, read the Sierra Club’s fact sheet (pdf) on this issue.

Factory farms tend to be located in rural areas next to communities that do not have the power to stop them/mobilize against them. This provision will further stack the deck against these communities. Anyone who thinks manure, pesticide runoff, ammonia, etc are not hazardous to the ecosystem and to human health needs to live next to one of these “farms”. I am hazarding a really wild guess that Congressman Hall (the sponsor) does not have to deal with issues such as these.

BBC NEWS | Science/Nature | Warming set to ‘devastate’ coral

Bleaching in 1998 occurred in all reef regions of the world; 16% of the world’s reefs were lost in that one year, alone. But the western Indian Ocean suffered most because of an interaction between El Nino and another periodic climate phenomenon called the Indian Ocean dipole.

In the seven years since, the damaged reefs have been largely unable to reseed. Many simply collapsed into rubble and became covered in algae.

This collapse removed food and shelter from predators for a large and diverse amount of marine life. The survey showed four fish species could already be locally extinct, and six species are at critically low levels.

The survey also revealed that the diversity of fish species in the heavily impacted sites had plummeted by about 50%.

Well, this is bad news, there has been earlier indication that coral reefs were not necessarily doomed by higher ocean temperatures because this would just cause a shift in the coral species to varieties thriving at higher temperatures/exhibiting adaptive behaviors. Obviously, this did not happen fast enough to regenerate the reef.

This is so sad, though there is more than a kernel of truth to it. Individual efforts mostly make people feel better about themselves (hey, I recycle, makes me feel good!). It is the Onion and it does go too far. Of course individual efforts add up, and more importantly, force the important players like government and big industry to modify their behavior just a little bit (at least that is what I tell myself).

Every day, without fail, I meticulously organize my recyclables into five distinct categories, thereby subtracting an eyedropper’s worth of garbage from the countless tons of waste that ferment in our landfills. It only takes a few extra minutes, but just think of the impact it totally lacks. I also refuse to use anything but “Earth-friendly” paper products—some of which contain up to 10 percent recycled materials. For me, it’s worth shouldering the extra cost, but, unfortunately, only a scant few of us bother to do the same. And growing some of my own organic vegetables in my backyard garden also, to my immense gratification, reduces the use of toxic chemical-based pesticides and herbicides present in corporate farming techniques by as much as 0.0000000000000000000000000000000000000001 percent.

News of possible interest only to me. It seems obvious that oil present in sediment enhances sorption and storage of PCBs than soot/black carbon. After all, it is a liquid phase and is present in higher amounts than black carbon. PCBs are so hydrophobic that almost any organic material has a higher affinity for PCBs than water/sediment. Carbon is a strong PCB adsorbent only for planar PCBs, and then only if it is itself graphitic, hence planar. In all other cases, oil should outcompete  carbon for PCBs. Glad they found experimental evidence. In all my (three) years of analyzing for PCBs, the oily samples are always the highest concentration ones.

Abstract:

The often-observed enhanced sorption of hydrophobic organic chemicals (HOCs) to sediments is frequently attributed to the presence of soot and soot-like materials. However, sediments may contain other hydrophobic phases, such as weathered oil residues. Previous experiments have shown that these residues can be efficient sorbents for certain PAHs. In this study we investigated sorption of PCBs to sediments contaminated with different concentrations and types of oils, and from that derived oil-water distribution coefficients (Koil). Sorption of PCBs to both fresh and weathered oils was proportional to sorbate hydrophobicity, and no effects of PCB planarity were observed. Furthermore, the experiments demonstrated that different oils sorbed PCBs similarly and extensively (Koil up to 108.3 for PCB 169), and that weathering caused an almost 2-fold increase in sorption of the lower chlorinated PCBs. Koil values indicated that at the PCB equilibrium concentrations tested (pg-ng/L range), for many congeners weathered oil is a stronger sorbent than pure soot and soot-like materials. Due to attenuation of adsorption to the latter materials in sediments (caused by competitive adsorption with organic matter), sedimentary weathered oil will therefore, if present as a separate phase, defeat sedimentary soot, coal, and charcoal as PCB sorbent in most cases. Consequently, weathered oil probably is the ultimate sedimentary sorbent for PCBs and should be included in HOC fate models.

Federal Study Finds Accord on Warming – New York Times

A scientific study commissioned by the Bush administration concluded yesterday that the lower atmosphere was indeed growing warmer and that there was “clear evidence of human influences on the climate system.”

Wait, we still need to study this more, we need to eliminate all uncertainty before we act, we need more proof, we need to be more certain :-;

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.

Seeing red over ‘green scare’ – Los Angeles Times:

For example, Gore blames the disappearing snows of Mt. Kilimanjaro on global warming, but a 2003 study in Nature identified the clear-cutting of surrounding moisture-rich forests as the culprit. In the famously fact-checked New Yorker, Editor David Remnick pens a love letter to Gore in which he laments that Earth will “likely be an uninhabitable planet” if we don’t heed Gore’s jeremiads. Oh … come … on!

Well, it’s hard to figure out where to begin refuting nonsense like this, which has been refuted a million times. You don’t take down scientific consensus by pointing out minor inaccuracies in work done by Al Gore, of all people. Yes, it can be argued (Kaser et al., INTERNATIONAL JOURNAL OF CLIMATOLOGY 24 (3): 329-339 MAR 15 2004) that Kilimanjaro’s ice cap regression may have to do more with loss of moisture than with temperature. That does not make a case of the “Green Meanie” ( typical demonising phrase – should we call Goldberg an ignorant ostrich, well, does not have the same evocativeness!). Repeat after me, one inaccuracy does not disprove millions of observations. I suggest he read Field Notes from a Catastrophe, written in language even he could understand to find  a few more experimental observations to “debunk”.

Major news media have gone after scientists who argue there’s still time to study global warming (IRAQ’s WMD – substitute) rather than plunge into some half-baked environmental jihad (IRAQ WAR – substitute) that could waste possibly trillions of dollars.

Sweet words coming out of one of the war’s most fervent supporters. I like people who can have it both ways on a single day and pretend to not see the contradictions.

Maybe he should read this editorial published right below his.
