Re: H2S isn't just a nasty smell
Ha! I read that as HS2. Too much time spent complaining on rail forums.
H2S is nasty. One of the effects it has is to paralyse the olfactory nerve, so you stop smelling it pretty quickly. As you go down the periodic table, the smell gets worse too. I have heard tell of one chap who was working with hydrogen telluride; when he got on the tube to go home, at the next stop the entire carriage emptied, but he couldn't smell a thing.
