Air samples and swab samples of the air conditioning vents were collected from 29 automobiles in the metropolitan region of Atlanta, GA, and cultured for fungi. Among the fungi observed, species of Acremonium, Aspergillus, Alternaria, Aureobasidium, Cladosporium, and Penicillium were in the highest densities. Transparent adhesive tape imprints, SEM observations, and enrichment culture of components of five systems demonstrated fungal hyphae on the metal surfaces and within the matrix of various insulation materials. The evaporator removed from one automobile because of a series of complaints of noxious odors was densely colonized by Penicillium viridicatum. The amplification of known allergenic and odor-producing fungi occurred within the automobile air conditioning systems.
