"The dispersant is the problem and the concern is air quality and the need to wear respirators of some sort."

Nope. Not so. The EPA is constantly monitoring at multiple sites all along the coast, in both air and water, and NO dispersant has been detected in either (with a lower detection limit of 500 ppb).

All the historical data on dispersant monitoring and all the other potential toxics is at the EPA's "Deepwater Horizon Response" website.

So, the Obama EPA is totally trustworthy. Okey doke.

“””While this is important information to have, additional testing is needed to further inform the use of dispersants. The next phase of EPA’s testing will assess at the acute toxicity of multiple concentrations of Louisiana Sweet Crude Oil alone and combinations of Louisiana Sweet Crude Oil with each of the eight dispersants for two test species.””””

Hmmm....
