   Actually metallic selenium, or some salts thereof - ain't bad.  But: 
when a selenium rectifier goes casters-up - it emits Hydrogen Sulphide gas 
- which is very, very much not good for you - and also the main component 
in what makes rotten eggs smell like rotten eggs.

   Been there, done that - used to fix old TVs and radios as a kid - had a 
big one in my room that made 28VDC for my Command Set collection in Jr. 
High - it let go one evening - we had a swamp cooler then - it was on - I 
lost most of my Points with the rest of the family....

    Cheers
