I confess to the same problem.  I do indoor air quality investigations
and am always sticking my nose in air conditioning units, attics and
the like.  I do worry a bit about getting some god-awful dose in the
quadrillions of mold spores up my nose one day.  I've never even heard
of a good substitute for one's nose though.  First of all, some of
these odors can be detected by the nose at concentrations that would
make your GC/MS give up - low parts per trillion.  Second, who even
knows what all these volatile secondary metabolites are?  I'm sure most
have never been identified or studied.
