EPA study finds controversial Gulf dispersant is not a serious risk

The Environmental Protection Agency said Wednesday that testing has shown that Corexit, the controversial chemical dispersant presently being dumped into the Gulf of Mexico to combat the oil spill, is practically nontoxic to slightly toxic.
In a statement posted to the agencys website, the EPA announced that none of the eight dispersants tested, including the product in use in the gulf, displayed biologically significant endocrine disrupting activity. The dispersants were tested on shrimp and small fish, but not on humans.”..........
Thank you, Kimberly.
However, the main problem with Corexit seems to be the very work of its being a dispersant. It breaks up the petroleum into its constituent parts. Therefore, instead of the naturally congealed crude coming to the surface, many toxins are released into the seawater.
Also, see the chart linked above, which shows the existence or other dispersants of less intrinsic toxicity.
