Buildings with indoor air quality (IAQ) complaints frequently have high airborne concentrations of Penicillium species, while buildings with few IAQ complaints have an indoor air (IDA) fungal ecology similar to outdoor air (ODA), where Cladosporium species is usually the dominant microorganism. These studies compared fungal air profiles, measured continually over 6 h in a documented sick building, in IDA in a room experiencing IAQ problems with fungal profiles measured concurrently in ODA. The dominant species collected at both sites were Penicillium species, Cladosporium species, and Alternaria species. In the IDA, Penicillium species were always the dominant organisms, ranging from 150 to 567 cfu/m3 (89.8-100% of the total fungi). In the ODA, Cladosporium species were dominant in four samples (40.0-70.6%), while Penicillium species were dominant (52.7-79.6%) in two. These data demonstrate that, even though ODA fungal profiles are changing continuously, IDA fungal profiles in "sick" buildings tend to remain unchanged.
存在室内空气质量（IAQ）问题投诉的建筑物中，空气中青霉菌属的浓度通常较高，而几乎没有IAQ问题投诉的建筑物，其室内空气（IDA）真菌生态与室外空气（ODA）相似，在室外空气中枝孢菌属通常是主要的微生物。这些研究比较了在一栋有记录的病态建筑中持续6小时测量的真菌空气分布情况，该建筑的一个房间存在IAQ问题，同时还比较了该房间室内空气（IDA）中的真菌分布与室外空气（ODA）中同时测量的真菌分布。在两个地点采集到的主要菌种为青霉菌属、枝孢菌属和链格孢属。在室内空气中，青霉菌属始终是主要生物，浓度范围为150至567 cfu/m3（占真菌总数的89.8 - 100%）。在室外空气中，枝孢菌属在四个样本中占主导（40.0 - 70.6%），而青霉菌属在两个样本中占主导（52.7 - 79.6%）。这些数据表明，尽管室外空气真菌分布在不断变化，但“病态”建筑中的室内空气真菌分布往往保持不变。
