Summary: “On CNN, Dr. Susan Shaw, Marine toxicologist
reported a gruesome condition of a shrimper who was exposed to Corexit 9500. He
suffered internal bleeding from the rectum, vomiting, and other problems. Dr. Shaw
overall states it is a problem of ocean pollution that will have a large impact
on marine life and humans. Dr. Susan Shaw has a Doctoral Degree (DrPH) in
Public Health/Environmental Health Sciences from Columbia University.”
Analysis: This CNN video from YouTube on Corexit use
in the gulf cleanup is neither valid nor invalid. It simply seems that the
situation remains unsolved till scientist can estimate its true make up, causes,
and affects. Main problem: they lack significant data on how dispersants affect
oil, what creatures live in deep water ecosystems, how to translate laboratory toxicity
test to conditions in the ocean , and how oil and dispersants affects marine
life, people, and other organisms over time.
Info on COREXIT:
Corexit 9500 is a solvent, originally developed by EXXON. it is now
Manufactured by Nalco of Naperville, Illinois. It is only toxic by 2.61 ppm
(parts per million) wile oil is at 11 ppm. Corexit is supposedly the most toxic
dispersal agent of its kind. But it is the dispersant that’s more toxic. It could
be the mixture of it and oil makes it much more toxic (this has yet to be
proved)
