“It’s completely scientifically dishonest to pooh-pooh the potential here when you are talking about some of the most toxic chemicals that we know,” said Kramer, who is founder and president of consulting firm Epidemiology International in Hunt Valley, Maryland.

Anybody who makes a comment like this is simply lying. The materials in the dispersant are nowhere NEAR being "the most toxic chemicals that we know". ALL of the components in the dispersants are COMMON HOUSEHOLD CHEMICALS, in use by thousand and tens of thousands of people every day. Simply because they happen to be mixed up and a sticker that says "Corexit 9500" is put on the tank does NOT automatically make them more toxis.
