Tests suggest oil dispersant washing up on Alabama beaches, Press-Register, August 6, 2010:
The stained, brown water seen washing up in pockets along Alabama beaches for the last two weeks appears to contain the dispersant widely used on oil from the Deepwater Horizon spill, according to a preliminary analysis.
Ed Overton, a Louisiana State University chemist... [who] is analyzing oil samples for the federal government... said... "indications [are] that there was a dispersant signal in the sample." ... [T]he signal was similar to a Corexit sample.
Harriet Perry, a scientist at the Gulf Coast Research Lab in Ocean Springs [said]... "It looks like they found [COrexit]," Perry said of work by research colleagues at Tulane University [researching crab larvae]... "For a droplet to be that small, it has to be dispersed oil... It's supposed to biodegrade rapidly. It's supposed to disappear in days, not weeks, but that may not be happening."
