Reply #3: Read the lab study - that was NOT the conclusion. Here's the link:

http://www.iosc.org/papers/00020.pdf That report - it's only one-page - did NOT say anything like "COREXIT 9500 was found to be one of the most toxic dispersant agents ever developed." It reported the levels at which it and 9517, the other Nalco dispersant, are toxic to various forms of aquatic life. In tiny concentrations of just a few ppms, it is toxic to marine life, particularly mollusks and fish eggs, which is itself really shocking. There is no mention of its effects on land life forms, and may not have been tested for that. That would also be shocking.

But, please do not distort the meaning of this.
