For indepth and quite devastating coverage of the BP induced crisis in the Gulf, I suggest looking at the World Socialist Website’s many great articles with a heavily leftist, but well researched and articulated, bent HERE.

Bea told the WSWS that a contact had provided him with a toxicity statement for Corexit, the dispersant BP is using—so far about 500,000 gallons have been dumped on the surface and near the seabed, and about 800,000 more gallons are on order. “It clearly says, if you breathe too much of it or if you ingest too much of it, if you let too much sit on your skin, it’ll kill you,” Bea said. “And of course I’m sitting here thinking if I’m a fish, I don’t know that.”
A Thursday report in the New York Times, “Less Toxic Dispersants Lose Out in BP Oil Spill Cleanup,” reveals that Corexit is one of the most highly toxic dispersants on the market, and one of the least effective.
“Of 18 dispersants whose use EPA has approved, 12 were found to be more effective on southern Louisiana crude than Corexit, EPA data show,” according to Paul Quinlan of the Times’ Greenwire blog. “Two of the 12 were found to be 100 percent effective on Gulf of Mexico crude, while the two Corexit products rated 56 percent and 63 percent effective, respectively. The toxicity of the 12 was shown to be either comparable to the Corexit line or, in some cases, 10 or 20 times less, according to EPA.”

So why is it being used? Once again, the most immediate profit concerns predominate. Corexit is produced by Nalco Co., a firm headed up by executives from both BP and industry leader Exxon. “It’s a chemical that the oil industry makes to sell to itself, basically,” said Richard Charter of Defenders of Wildlife.
