The use of volatile organic compounds (VOCs) to detect mold growth in
damp buildings depends on a comprehensive knowledge of the biosyntheti
c pathways available to indoor molds as well as their biological varia
tion. Recent reports concerning (VOCs) formed during the growth of mol
ds from damp buildings on laboratory substrates indicate considerable
variation, presumably because of the sensitivity of mold VOC biosynthe
sis to environmental conditions or large biological variation.
