Odor is a
volatilized
chemical
compound,
generally at
a very low
concentration,
that humans
or other
animals
perceive by
the sense of
smell..This
sense is
mediated by
specialized
sensory
cells of the
nasal
cavity.
The widest
range of
odors
consists of
organic
compounds
such as
mercaptans,
amins,
indoles,
scatoles,
etc.;
although
some
inorganic
substances,
such as
hydrogen
sulfide and
ammonia, are
also
odorants. |
