摘要：
A survey about mold problems in Finnish homes was made. Of the 135 reported cases 30 homes were chosen for bioaerosol measurements. Indoor and outdoor air fungal spores and bacteria were sampled in the spring and fall. Corresponding data, gathered from 18 reference homes sampled in the spring, were used as reference material. The range of the fungal spore levels was 10-2300 colony-forming units/m3 (cfu/m3) in moldy homes and 165-850 cfu/m3 in the reference homes. The mean indoor/outdoor ratio of fungal spores in moldy homes was 4.2 vs. 0.6 in the reference homes. Mesophilic actinomycetes were found in moldy homes but not in the reference homes. No thermophilic actinomycetes were found in moldy or reference homes. In seven complaint sites the total bacteria levels were exceedingly high, 4500-12 200 cfu/m3, which probably resulted from poor ventilation.
