First study of dispersants in Gulf spill suggests a prolonged deepwater fate
Date:1/26/2011

ype of dispersant/hydrocarbon combination in the deep ocean, she added, "We need toxicity studies."

"The decision to use chemical dispersants at the sea floor was a classic choice between bad and worse," Valentine said. "And while we have provided needed insight into the fate and transport of the dispersant we still don't know just how serious the threat is; the deep ocean is a sensitive ecosystem unaccustomed to chemical irruptions like this, and there is a lot we don't understand about this cold, dark world."

"The good news is that the dispersant stayed in the deep ocean after it was first applied," Kujawinski says. "The bad news is that it stayed in the deep ocean and did not degrade."
