WHERE did you come up with this??? 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."

Smiling takes 6.

I'm lazy.
All this link does is show that the media is just as gullible as you are. NONE of those levels is terribly dangerous. You are exposed to more than that (for the hydrocarbons) every time you fill up the gas tank on your car. And all 1.2 ppm of H2S does is cause a stink. It will NOT kill or injure you.
HERE is accurate information:
At some threshold level, believed to average around 300–350 ppm, the oxidative enzymes become overwhelmed. Many personal safety gas detectors, such as those used by utility, sewage and petrochemical workers, are set to alarm at as low as 5 to 10 ppm and to go into high alarm at 15 ppm."
Dude, I'm a chemist (PhD). I "know" about chemistry, and about the toxicity of chemicals. And I certainly know at least how to SPELL the words. NO American regulatory agency would mis-spell chemical names as are done in your post. Your source is bogus, as is the information contained therein. Not worth the electrons used to transmit it.
