BP CHOSE MORE TOXIC, LESS EFFECTIVE OIL DISPERSANT -- GUESS WHY ...

"...Corexit and manufactured by Nalco Co., a company that was once part of Exxon Mobil Corp. and whose current leadership includes executives at both BP and Exxon. And another 805,000 gallons of Corexit are on order, the company said, with the possibility that hundreds of thousands of more gallons may be needed if the well continues spewing oil for weeks or months.

But according to EPA data, Corexit ranks far above dispersants made by competitors in toxicity and far below them in effectiveness in handling southern Louisiana crude.
Of 18 dispersants whose use EPA has approved, 12 were found to be more effective on southern Louisiana crude than Corexit, EPA data show. 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."

UPDATE
Climate Progress’ Joe Romm notes that as toxic as Corexit is, dispersed oil is more toxic.

Out of Sight: BP’s dispersants are toxic — but not as toxic as dispersed oil


Plus the threat the disaster poses to America's primary coral reef


Chemically dispersing oil spills “solves the political problem of visible oil but not the environmental problem,” Robert Brulle, a 20-year Coast Guard veteran and an affiliate professor of public health at Drexel University, told me. These dispersants “do not actually reduce the total amount of oil entering the environment,” as a 2005 National Academy of Sciences report on the subject put it.
In short: out of sight, out of mind. But not out of the body of marine life.
Dispersants decrease the amount of oil that directly reaches the shores or the creatures that live on the shores or sea surface. But they increase the exposure to oil by creatures that live in the water or on the sea floor — like, say, shrimp or oysters.

As Jim Hightower explains it, is that “the wealthiest 1 percent of Americans possess more net worth today than the bottom 90 percent of us combined. Worse, these privileged few and their political henchmen have structured a new economic ‘normal’ of long-term joblessness, low wages, no benefits or worker rights, miserly public services, and a steadily widening chasm between the rich and the rest of us.” We must restore sanity to this nation.
