Photo: British Petroleum (BP) mix of oil spill and extremely toxic Corexit from after the Deepwater Horizon explosion, and the biggest oil spill in world history of approximately 210 million gallons (780,000 cubic meters) of Louisiana sweet crude oil into the Gulf of Mexico on April 20, 2010! The spill covered up to 68,000 square miles or 180,000 square kilometers!
Three years ago, when BP’s Deepwater Horizon began leaking some 210 million gallons of Louisiana Crude into the Gulf of Mexico, the U.S. government allowed the company to apply chemical “dispersants” to the blossoming oil slick to prevent toxic gunk from reaching the fragile bays, beaches, and mangroves of the coast, where so much marine life originates. But a number of recent studies show that BP and the feds may have made a huge mistake, for which everything from microscopic organisms to bottlenose dolphins are now paying the highest price.
After the spill, BP secured about a third of the world’s supply of dispersants, namely Corexit 9500 and 9527, according to The New York Times. Of the two, 9527 is more toxic. Corexit dispersants emulsify oil into tiny beads, causing them to sink toward the bottom. Wave action and wind turbulence degrade the oil further, and evaporation concentrates the toxins in the oil-Corexit mixture, including dangerous compounds called polycyclic aromatic hydrocarbons (PAHs), known to cause cancer and developmental disorders.
When BP began spraying the Gulf, critics cried foul. They said Corexit is not only toxic to marine life on its own, but when combined with crude oil, the mixture becomes several times more toxic than oil or dispersant alone.
Not surprisingly, BP Chief Executive Bob Dudley defended use of the dispersant. “The toxicity of Corexit is about the same as dish soap, which is effectively what it is and how it works,” he told stockholders. “In hindsight no one believes that that was the wrong thing and it would have been much worse without the use of it. I do not believe anybody—anybody with almost common sense—would say waves of black oil washing into the marshes and beaches would have been a better thing, under any circumstances.”
BP says that Corexit is harmless to marine life, while the Environmental Protection Agency has waffled, saying both that “long term effects [of dispersants] on aquatic life are unknown” and that data “do not indicate any significant effects on aquatic life. Moreover, decreased size of the oil droplets is a good indication that, so far, the dispersant is effective.”
But many scientists, such as Dr. William Sawyer, a Louisiana toxicologist, argue that Corexit can be deadly to people and sea creatures alike. “Corexit components are also known as deodorized kerosene,” Sawyer said in a written statement for the Gulf Oil Disaster Recovery Group, a legal consortium representing environmental groups and individuals affected by the Deepwater Horizon spill. “With respect to marine toxicity and potential human health risks, studies of kerosene exposures strongly indicate potential health risks to volunteers, workers, sea turtles, dolphins, breathing reptiles and all species which need to surface for air exchanges, as well as birds and all other mammals.” When Corexit mixes with and breaks down crude, it makes the oil far more “bioavailable” to plants and animals, critics allege, because it is more easily absorbed in its emulsified state.

Sawyer tested edible fish and shellfish from the Gulf for absorption of petroleum hydrocarbon (PHC), believed to have been facilitated by Corexit. Tissue samples taken prior to the accident had no measurable PHC. But after the oil spill, Sawyer found tissue concentrations up to 10,000 parts per million, or 1 percent of the total. The study, he said, “shows that the absorption [of the oil] was enhanced by the Corexit.”
In April 2012, Louisiana State University’s Department of Oceanography and Coastal Sciences was finding lesions and grotesque deformities in sea life—including millions of shrimp with no eyes and crabs without eyes or claws—possibly linked to oil and dispersants.
The shocking story was ignored by major U.S. media, but covered in depth by Al Jazeera. BP said such deformities were “common” in aquatic life in the Gulf and caused by bacteria or parasites. But further studies point back to the spill.
A just-released study from the University of South Florida found that underwater plumes of BP oil, dispersed by Corexit, had produced a “massive die-off” of foraminifera, microscopic organisms at the base of the food chain. Other studies show that, as a result of oil and dispersants, plankton have either been killed or have absorbed PAHs before being consumed by other sea creatures.
Hydrocarbon-laden, mutated seafood is not the only legacy left behind by Corexit, many scientists, physicians, environmentalists, fishermen, and Gulf Coast residents contend. Earlier this week, TakePart wrote about Steve Kolian, a researcher and founder of the nonprofit group EcoRigs, whose volunteer scientists and divers seek to preserve offshore oil and gas platforms after production stops, for use as artificial reefs and for alternative energy production.

EcoRigs divers took water and marine life samples at several locations in the months following the blowout. Now, they and countless other Gulf residents are sick, with symptoms resembling something from a sci-fi horror film, including bleeding from the nose, ears, breasts, and even anus. Others complain of cognitive damage, including what one man calls getting “stuck stupid,” when he temporarily cannot move or speak, but can still hear.
“If we are getting sick, then you know the marine life out in the Gulf is too,” Kolian said. The diver and researcher completed an affidavit on human and marine health used in GAP’s report.
Kolian’s team has done studies of their own to alarming results. “We recently submitted a paper showing levels of hydrocarbons in seafood were up to 3,000 times higher than safety thresholds for human consumption,” he said. “Concentrations in biota [i.e. all marine life] samples were even greater.”
Kolian’s friend and colleague, Scott Porter, described in his affidavit to GAP how Corexit had caused dispersed crude to coat the bottom of the sea in a sickening, deadly film. In July 2011, he and other divers traveled to a part of the Florida Panhandle, known as the Emerald Coast for its pristine seawater, to collect samples for the Surfrider Foundation.
“When we went diving, however, the water had a brownish white haze that resembled what we saw in offshore Louisiana at 30 feet below sea level,” Porter’s affidavit stated. “I have never witnessed anything like that since I began diving in the Emerald Coast 20 years ago. We witnessed…a reddish brown substance on the seafloor that resembled tar and spanned a much larger area than is typical of natural runoff.”
In areas covered with the substance, “we noticed much less sea life,” Porter continued. “There were hardly any sand dollars or crabs and only some fish, whereas we would normally see an abundance of organisms. It was desolate.”

However, the oil well was not officially capped and finally sealed until September 19, 2010! Reports continue to circulate that the well still leaks an estimated 400 gallons of oil per day into the gulf! Enjoy your seafood!
“It’s as safe as Dawn dishwashing liquid.” That’s what Jamie Griffin says the BP man told her about the smelly, rainbow-streaked gunk coating the floor of the “floating hotel” where Griffin was feeding hundreds of cleanup workers during the BP oil disaster in the Gulf of Mexico. Apparently, the workers were tracking the gunk inside on their boots. Griffin, as chief cook and maid, was trying to clean it. But even boiling water didn’t work.
“The BP representative said, ‘Jamie, just mop it like you’d mop any other dirty floor,’” Griffin recalls in her Louisiana drawl.
Griffin did as she was told: “I tried Pine-Sol, bleach, I even tried Dawn on those floors.” As she scrubbed, the mix of cleanser and gunk occasionally splashed onto her arms and face.
Within days, the 32-year-old single mother was coughing up blood and suffering constant headaches. She lost her voice. “My throat felt like I’d swallowed razor blades,” she says.
Then things got much worse.
Like hundreds, possibly thousands, of workers on the cleanup, Griffin soon fell ill with a cluster of excruciating, bizarre, grotesque ailments. By July, unstoppable muscle spasms were twisting her hands into immovable claws. In August, she began losing her short-term memory. After cooking professionally for 10 years, she couldn’t remember the recipe for vegetable soup; one morning, she got in the car to go to work, only to discover she hadn’t put on pants. The right side, but only the right side, of her body “started acting crazy. It felt like the nerves were coming out of my skin. It was so painful. My right leg swelled—my ankle would get as wide as my calf—and my skin got incredibly itchy.”
“These are the same symptoms experienced by soldiers who returned from the Persian Gulf War with Gulf War syndrome,” says Dr. Michael Robichaux, a Louisiana physician and former state senator, who treated Griffin and 113 other patients with similar complaints. As a general practitioner, Robichaux says he had “never seen this grouping of symptoms together: skin problems, neurological impairments, plus pulmonary problems.” Only months later, after Kaye H. Kilburn, a former professor of medicine at the University of Southern California and one of the nation’s leading environmental health experts, came to Louisiana and tested 14 of Robichaux’s patients did the two physicians make the connection with Gulf War syndrome, the malady that afflicted an estimated 250,000 veterans of that war with a mysterious combination of fatigue, skin inflammation, and cognitive problems.
BP claims to have used 1.8 million gallons of Corexit, about 1/3 of the world’s supply, to ‘disperse’ the oil spill! The Coast Guard granted BP 74 exemptions for Corexit surface use in 48 days! The EPA and the federal government were aware of this!
