    Hydrogen sulfide is also detectable in very small amounts. I am very 
familiar with it since some photographic chemicals, notably toners, 
produce enough to require use out of doors.  You might also mention 
sulfur dioxide, another gas emitted by photographic chemicals, notably 
acid fixing baths. I happen to be sensitive to it, it can trigger asthma 
like symptoms.  Fortunately, its possible to avoid it in chemical 
photography.  There are lots and lots of chemical hazards, many hiding 
under the kitchen sink (or wherever you put your cleaning stuff). When I 
was a kid one of the farm kids I knew managed to drink lye! But he came 
from an accident prone family.
