EPA report on effects of using chemical dispersants in the Gulf oil spill

"It will take some time for us to find out whether nature's own forces have been able to deal with much larger amount of oil than we thought possible – or whether there are going to be large effects from dispersed oil that are hard to see right now, but which may be with us for some time – effects less physical but just as profound."

-- Richard Denison, a senior scientist with the Environmental Defense Fund in Washington, on research from the US Environmental Protection Agency (EPA) showing BP did not make things worse by using dispersants to combat the Gulf oil spill
