What is Corexit for oil?
One commonly used brand name is Corexit, but there are dozens of different dispersant mixtures. They work by breaking up oil slicks into lots of small droplets, similar to how dish detergent breaks up the greasy mess on a lasagna pan.
Why did BP use Corexit?
Conclusions from the report strongly suggest that the dispersant Corexit was widely applied in the aftermath of the Deepwater Horizon explosion because it caused the false impression that the oil disappeared. In reality, the oil/Corexit mixture became less visible, yet much more toxic than the oil alone.
Is Corexit still used today?
The use of Corexit is approved in the US by the U.S. Environmental Protection Agency (EPA).
Is Corexit still being used?
COREXIT 9500 is the chemical dispersant currently being used in the Gulf in attempts to remedy the Deep Water Horizon spill. It is produced by the Nalco company and they have sold at least $40 million of the product to BP.
Is Corexit toxic to marine organisms?
Our results indicate that Corexit 9500A is highly toxic to microzooplankton, particularly to small ciliates, and that the combination of dispersant with crude oil significantly increases the toxicity of crude oil to microzooplankton.
How bad was the BP oil spill?
— On April 20th, 2010, a BP oil rig called Deepwater Horizon exploded 50 miles off the coast of Louisiana. Eleven people were killed and the explosion triggered the biggest marine oil spill in global history. “All hell broke loose. A total of five million barrels of oil spilled into the gulf.

Corexit 9527, considered by the EPA to be an acute health hazard, is stated by its manufacturer to be potentially harmful to red blood cells, the kidneys and the liver, and may irritate eyes and skin. Like 9527, 9500 can cause hemolysis (rupture of blood cells) and may also cause internal bleeding.

Will Corexit be used for future deepwater drilling?
As deepwater drilling expands off U.S. coasts, it is inevitable that other incidents will occur. Renewed reliance on Corexit is planned for future oil spills, and BP has declared it will continue to use the deadly dispersant as long as the government permits doing so.
