a little bit about what they are using.The dispersal agent Corexit 9500 is a solvent originally developed by Exxon and now manufactured by the Nalco Holding Company of Naperville, Illinois that is four times more toxic than oil (oil is toxic at 11 ppm (parts per million), Corexit 9500 at only 2.61ppm). In a report written by Anita George-Ares and James R. Clark for Exxon Biomedical Sciences, Inc. titled “Acute Aquatic Toxicity of Three Corexit Products: An Overview” Corexit 9500 was found to be one of the most toxic dispersal agents ever developed. Even worse, according to this report, with higher water temperatures, like those now occurring in the Gulf of Mexico, its toxicity grows.

The United States Environmental Protection Agency (EPA) in discovering BP’s use of this dangerous dispersal agent ordered BP to stop using it, but BP refused stating that their only alternative to Corexit 9500 was an even more dangerous dispersal agent known as Sea Brat 4.

The main differences between Corexit 9500 and Sea Brat 4 lie in how long these dangerous chemicals take to degrade into their constituent organic compounds, which for Corexit 9500 is 28 days. Sea Brat 4, on the other hand, degrades into an organic chemical called Nonylphenol that is toxic to aquatic life and can persist in the environment for years.

A greater danger involving Corexit 9500, and as outlined by Russian scientists in this report, is that with its 2.61ppm toxicity level, and when combined with the heating Gulf of Mexico waters, its molecules will be able to “phase transition” from their present liquid to a gaseous state allowing them to be absorbed into clouds and allowing their release as “toxic rain” upon all of Eastern North America.

Even worse, should a Katrina like tropical hurricane form in the Gulf of Mexico while tens of millions of gallons of Corexit 9500 are sitting on, or near, its surface the resulting “toxic rain” falling upon the North American continent could “theoretically” destroy all microbial life to any depth it reaches resulting in an “unimaginable environmental catastrophe” destroying all life forms from the “bottom of the evolutionary chart to the top”.
