The concentrations of bacterial and fungal bioaerosols were measured in a retirement home and a school dormitory from May 2012 to May 2013. In the present work, two active and passive methods were used for bioaerosol sampling. The results from the present work indicated that Bacillus spp., Micrococcus spp., and Staphylococcus spp. were the dominant bacterial genera, while the major fungal genera were Penicillium spp., Cladosporium spp., and Aspergillus spp. The results also indicated that the indoor-to-outdoor (I/O) ratios for total bacteria were 1.77 and 1.44 in the retirement home and the school dormitory, respectively; the corresponding values for total fungal spores were 1.23 and 1.08. The results suggested that in addition to outdoor sources, indoor sources also played a significant role in emitting bacterial and fungal bioaerosols in the retirement home and the school dormitory indoor.
2012年5月至2013年5月期间，在一家养老院和一所学校宿舍对细菌和真菌生物气溶胶的浓度进行了测量。在本研究中，使用了两种主动和被动方法进行生物气溶胶采样。本研究结果表明，芽孢杆菌属、微球菌属和葡萄球菌属是主要的细菌属，而主要的真菌属是青霉属、枝孢菌属和曲霉属。结果还表明，养老院和学校宿舍中总细菌的室内外（I/O）比值分别为1.77和1.44；总真菌孢子的相应值分别为1.23和1.08。结果表明，除了室外来源外，室内来源在养老院和学校宿舍室内排放细菌和真菌生物气溶胶方面也起着重要作用。
