WHERE did you come up with this??? Any hydrogen sulfide immediately dissolves in seawater, and then precipitates as a harmless solid, as soon as it finds a calcium or iron ion.
3000 ppb (actual 3 ppm) of benZENE (not benZINE) is about what is normally present in gasoline. You breath it every time you fill your cars gas tank. Have you died yet???
And "metholine chloride" (actually methylene chloride) is not a constituent of oil, nor is it naturally found in the earth. So this has to be total bullshit.
And your ravings about Corexit are completely nuts. There is nothing in Corexit that has that kind of toxicity.
Some of my "completely nuts ravings" cited right here, little man:

Excerpt:
A more recent report published by the Natural Resources Defense Council (NRDC) analyzes offshore air quality data released by BP. The findings replicate conclusions in earlier reports that the level of toxins in the air is unsafe for humans. "Nearly 70% (275 out of 399) of offshore air samples had detectable levels of hydrocarbons and nearly 1 in 5 (73 out of 399) had levels greater than 10 parts per million (ppm), which is an EPA cutoff level for further investigation. 6 samples exceed 100 ppm which in a previous monitoring summary was labeled as the action limit."
