Rubbish
Hydrogen sulfide is considered a broad-spectrum poison, meaning that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H2S is comparable with that of hydrogen cyanide. It forms a complex bond with iron in the mitochondrial cytochrome enzymes, thereby blocking oxygen from binding and stopping cellular respiration.
Since hydrogen sulfide occurs naturally in the body, the environment and the gut, enzymes exist in the body capable of detoxifying it by oxidation to (harmless) sulfate.[6] Hence, low levels of sulfide may be tolerated indefinitely.

REALLY?????
Oh my Gosh! So this means that what could have caused an extinction of the dinosaurs, (which left mammals in place, obviously) really is the hydrogen sulfide. But mammals, like humans, would not be as effected by the gas...
I love Free Republic, seriously. You guys are awesome!
