Oil Spill Commission report: Evidence indicates "ionic surfactant" in Corexit 9527 & 9500 "inhibits biodegradation"; "Dispersants and dispersed oil are typically more toxic than oil"


Reports Detail Confusion During Oil Disaster, Courthouse News Service, October 8, 2010:

"[D]ispersants and dispersed oil are typically more toxic than oil alone to embryos and larvae."... [t]he dispersant report says...

"Little or no prior testing had been done on the effectiveness and potential adverse environmental consequences of subsea dispersant use, let alone at those volumes," the report states.

"[S]ome evidence indicates that ionic surfactant in Corexit 9527 and 9500 inhibits biodegradation..."

  • I would like to point out that there are published results as to what this substance does in one of Dr. Riki Ott's books. She had the documents published about the health effects from the Exxon Valdez spill before they were order to be sealed till 2023. However, we are now finding out they have many versions of corexit more than mentioned in this article.

    Sure, there was little or no prior testing. There sure as hell is a big experiment going on right now in the Gulf of Corexito! Bastards.

    2-BUTOXY ETHANOL is a main ingredient in Corexit EC9527A (30-60%)- BP used this Corexit throughout April and May [at least]. According the the "Hazardous Substance Fact Sheet" about 2-BUTOXY ETHANOL, it is a "serious" health hazard for humans, it has been shown to cause liver cancer in animals.

    MSDS on Corexit EC9527A says:
    "**EMERGENCY OVERVIEW**
    WARNING
    Eye and skin irritant. Repeated or excessive exposure to butoxyethanol may cause injury to red blood cells
    (hemolysis), kidney or the liver. Harmful by inhalation, in contact with skin and if swallowed."

    "ENVIRONMENTAL PRECAUTIONS :
    Do not contaminate surface water"

    "HUMAN HAZARD CHARACTERIZATION :
    Based on our hazard characterization, the potential human hazard is: High."

    "SYMPTOMS OF EXPOSURE :
    Acute :
    Excessive exposure may cause central nervous system effects, nausea, vomiting, anesthetic or narcotic effects.
    Chronic :
    Repeated or excessive exposure to butoxyethanol may cause injury to red blood cells (hemolysis), kidney or the
    liver."

    Corexit 9527 "is readily absorbed through the skin".

    BP switched to Corexit 9500 yet the MSDS for this says, "No toxicity studies have been conducted on this product."

    BP dumped millions of gallons of this stuff into our water. How in the world does anyone that water is safe or that seafood from that same water is safe to eat?!!!

    Middle school science and logic can figure this out. Smart aren't they? lol
