Mr. President, my concern is that this toxic and damaging chemical [Corexit, produced by Nalco] is still being used and it will compound the long-term damage to our state, our citizens, our eco-system, our economy, our seafood industry, our wildlife and our culture...Due to the threats to public safety and ecological realities, I am compelled to write this letter requesting answers to my questions regarding the role of the United States Government in administering the response to the crises in the Gulf. It is apparent that the response directed by our government was inadequate because it allowed the use of Corexit dispersants which increased the toxicity level of the spilled oil and delivered no substantial benefit... Have acutely toxic chemical compounds been formed by the mixing of Gulf crude with toxic dispersants...?
