Sorry, Georgia boys, but that so-called report is about as useful as trying to piss into the wind during a hurricane. NOT ONE concentration number anywhere to be found, and it is the CONCENTRATION of the oil that determines toxicity...nothing more, nothing less. The highest number I have seen ANYWHERE is 5 ppm for oil in the plumes, which is well below the toxicity limit for anything but a very few highly vulnerable marine species (and mostly the larvae of them, not the adult forms). And that number was from weeks ago. The concentration today is probably MUCH, MUCH less.
The oil that is in the Gulf is disappearing due to a large number of different removal mechanisms. If the oil is present as suspended microscopic droplets, it's pretty much harmless, and getting more harmless as time passes.
