The manufacturer's safety data sheet states "No toxicity studies have been conducted on this product," and later concludes "The potential human hazard is: Low." (
well isn't that just a ray of reassuring sunshine on an otherwise shitty day?)
According to the Alaska Community Action on Toxics, the use of Corexit during the Exxon Valdez oil spill caused "respiratory, nervous system, liver, kidney and blood disorders" in people.[9] According to the EPA, Corexit is more toxic than dispersants made by several competitors and less effective in handling southern Louisiana crude.
Reportedly Corexit is toxic to marine life and helps keep spilled oil submerged. The quantities used in the Gulf will create 'unprecedented underwater damage to organisms.'[16] 9527A is also hazardous for humans: 'May cause injury to red blood cells (hemolysis), kidney or the liver'.
