Digital BW, The Print

Cellulose appears to act like a sponge for the glycols that cause the
out-gassing with glossy (barrier) papers.  As such, in addition to air
drying, leaving the print pressed under some plain paper over night will
soak up a fair amount of these chemicals.

I've never heard of one, and if anyone has scientific data I'd love to see
it.

Based on what I've seen and measured I think 24-hours is 
best--minimum. If you're a paranoid wait 96-hours, but I think 
anything beyond that would be splitting hairs.

Most definitely. With high humidity (in the 80s and 90s) I'd wait a 
lot longer, but then I wouldn't want to store my prints in those 
conditions...
