Indoor aeromycota in relation to residential characteristics and allergic symptoms.

Describes a study of indoor aeromycota in 15 homes in Canada. Significant differences in airborne spore concentrations were found in the different types of room. Living rooms held the highest count of airborne propagules, followed by family rooms, kitchens, bathrooms and bedrooms. Kitchens had the greatest variety of fungi. Increased numbers of spores were the result of dampness and carpets, in general. Concentrations of airborne fungi were found to be reduced by the presence of forced air heating systems, humidifiers, air filters and air conditioners. Susceptible persons were found to report less irritation in homes with air conditioners, air filters, humidifiers and forced air heating systems. More irritation/allergic reactions were reported in damp dwellings.
