Exaust Smell?

Ouch! I'd forgotten about that! I DO think you're right about it being regulated, probably to prevent formation of sulfuric acid compounds, which ARE dangerous. And, I see from Wikipedia that some people can have deadly allergic reactions to it. However, we all know from chemistry lab days that it takes very little sulfur dioxide to make a stink bomb and you certainly smell it around geysers, volcanoes and even some hot springs.

I imagine our noses are very sensitive to even minute amounts of that compound - amounts that are below any regulated limit.

Thanks for keeping me humble and reminding me I don't know everything, Lars!
