The EPA has been monitoring levels of Benzene, Hydrogen Sulfide and other VOCs (Volatile Organic Compounds) around the Gulf Coast and is finding that the gasses are reaching levels that are known to cause illness. Both BP and the Federal Government are well aware of these gasses and their health effects but all I have heard BP say about the growing number of people becoming ill is that they, "probably have food poisoning."
The EPA is posting their finding on their website at:http://www.epa.gov/bpspill/
Edit: Forgot to mention to wait around for the second video that started as soon as this one is finished...
Thanks for reminding us "Porksandwich"
