I will predict that the air is fine and everyone should take a deep breath
with little concern.  The degradation of Latex products you describe is
quite common and more accelerated as we all switch to cheaper products made
with inferior raw materials.  Some of the currently available Latex gloves
are so filled with contaminants (used as fillers) spontaneous combustion
during shipment has been observed.

The photographic degradation is also more common now due to inferior inks
and dyes.  Unless the prints were made using platinum salts degradation is

Hi Gang:

Excusing the cross-posting....  We have researchers whose latex gloves,
rubber bands and other latex-containing articles degrade at an alarming
rate.  This is annoying.  Lately, a photographer in this building has found
her images degrading as well.  This is now causing consternation amongst
building occupants.

All the obvious have been checked - it is a laboratory building with
one-pass air and the degradation is not localized to a single floor or lab.

Ideas?  Don't be shy about suggesting the outrageous.
