BP’s Corexit Oil Tar Sponged Up by Human Skin

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.

The report states: “Toxicology studies to determine effects of Corexit® dispersant on dermal absorption rates of carcinogenic PAHs through wet skin are needed to assess risk to human health and safety.”

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:

  1. 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.
  2. 26 of 32 sampling sites in Florida and Alabama had PAH concentrations exceeding safe limits. 
  3. Only three locations were found free of PAH contamination.
  4. 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.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
