BP's Corexit Oil Tar Sponged Up by Human Skin

Mother Jones

The Surfrider Foundation has released its preliminary "State of the Beach" study for the Gulf of Mexico from BP's ongoing Deepwater Horizon disaster.

Sadly, things aren't getting cleaner faster, according to their results. The Corexit that BP used to "disperse" the oil now appears to be making it tougher for microbes to digest the oil. I wrote about this problem in depth in "The BP Cover-Up."

The persistence of Corexit mixed with crude oil has now weathered to tar, yet is traceable to BP's Deepwater Horizon brew through its chemical fingerprint. The mix creates a fluorescent signature visible under UV light. From the report:

The program uses newly developed UV light equipment to detect tar product and reveal where it is buried in many beach areas and also where it still remains on the surface in the shoreline plunge step area. The tar product samples are then analyzed…to determine which toxins may be present and at what concentrations. By returning to locations several times over the past year and analyzing samples, we've been able to determine that PAH concentrations in most locations are not degrading as hoped for and expected.

Worse, the toxins in this unholy mix of Corexit and crude actually penetrate wet skin faster than dry skin (photos above)—the author describes it as the equivalent of a built-in accelerant—though you'd never know it unless you happened to look under fluorescent light in the 370nm spectrum. The stuff can't be wiped off. It's absorbed into the skin.

And it isn't going away. Other findings from monitoring sites between Waveland, Mississippi, and Cape San Blas, Florida over the past two years:

The use of Corexit is inhibiting the microbial degradation of hydrocarbons in the crude oil and has enabled concentrations of the organic pollutants known as PAH to stay above levels considered carcinogenic by the NIH and OSHA.

26 of 32 sampling sites in Florida and Alabama had PAH concentrations exceeding safe limits.
Only three locations were found free of PAH contamination.

Carcinogenic PAH compounds from the toxic tar are concentrating in surface layers of the beach and from there leaching into lower layers of beach sediment. This could potentially lead to contamination of groundwater sources.

Toxic Gulf Brew Still Reaping Death and Misery

Pure Energy Systems News, Mar. 12, 2011

The crude oil that gushed into the Gulf of Mexico (while BP continually under-reported the flow rate of gushing oil) was obviously harmful to the ecologic environment. However, instead of utilizing safe techniques to remove their toxic sludge they chose fast and risky methods to remove as much oil as possible from the public eye. In order to minimize the public relations nightmare and hide much of the magnitude of their guilt, chemical dispersants were utilized.

Disturbingly, BP had many alternative dispersants at their disposal that exhibit less toxicity [than Corexit]. One of these is named, "Dispersit" and is made by Polychem, a division of U.S. Polychemical Corporation. It is claimed to be water based, non-toxic, and poses almost no risk to humans. However, even if BP had not chosen to use Dispersit, they had a dozen other EPA approved dispersants on a list they could have chosen from. For some reason these safer alternatives were ignored.

News Release : First Study of Dispersants in Gulf Spill Suggests a Prolonged Deepwater Fate

Source: Woods Hole Oceanographic Institution, Jan. 27, 2010

To combat last year’s Deepwater Horizon oil spill, nearly 800,000 gallons of chemical dispersant were injected directly into the oil and gas flow coming out of the wellhead nearly one mile deep in the Gulf of Mexico. Now, as scientists begin to assess how well the strategy worked at breaking up oil droplets, Woods Hole Oceanographic Institution (WHOI) chemist Elizabeth B. Kujawinski and her colleagues report that a major component of the dispersant itself was contained within an oil-gas-laden plume in the deep ocean and had still not degraded some three months after it was applied.

“We don’t know if the dispersant broke up the oil,” she added. “We found that it didn’t go away, and that was somewhat surprising.”
