Yes its Hydrogen Sulphide (H2S) aka: rotten egss, aaka: OMF's
Chemistry 101:
H2S is actually a more toxic gas that Hygrogen Cyanide ??? And the really evil thing is that after the first few seconds of exposure to a DANGEROUS level off the gas the olfactory sensors shut down and you can no longer smell it.
Thats why its so Ef**n dangerous.
It is heavier that air and that is why you should never enter a sewer or slurry pit without the Gas meters and PPE!!
I prefer the practical rather than theoretical, as in the recent demonstration caught on infrared security cameras at a US airport.
Professor that looks lighter than air?
