EPA finds that BP dispersants are no worse than others

The EPA released the results of its second phase of texts on oil dispersants today, which show that the dispersant BP has used in the Gulf of Mexico oil spill has about the same toxicity as seven other dispersants tested.
The lab results show that BP’s chosen dispersant, Corexit 9500A, when mixed with Louisiana Sweet Crude Oil is “generally no more or less toxic” than mixtures of the oil and other dispersants, according to the EPA.
