Abstract
Water extracts of thermal and acoustic fiberglass insulations used in the duct work of heating, ventilation and air conditioning (HVAC) systems supported germination of conidia and growth ofAspergillus versicolor (Vuillemin) Tiraboschi 1908–9 andAspergillus fumigatus Fresenius 1863. Urea, formaldehyde and unidentified organics were detected in the extracts. Formaldehyde in concentrations similar to those found in the extracts restricted the growth of both species in enriched media.A. versicolor, the more common species associated with fiberglass insulations, was more resistant to formaldehyde thanA. fumigatus.Keywords
