In this study, we investigated indoor air quality and symptoms of respiratory illness in 264 nursing workers at 28 day-care centers in Taipei. Geometric mean concentrations of indoor and outdoor bacteria were 735 colony-forming units in air (CFU/m3) and 384 CFU/m3, respectively. In addition, geometric mean concentrations of indoor and outdoor fungi were 1,212 CFU/m3 and 1,032 CFU/m3, respectively. Aspergillus, Cladosporium, and Penicillium-microfungi that occurred most commonly-were found indoors and outdoors. Geometric mean concentrations of house dust mite allergens, Der p I and Der p V, were 58 ng/g dust and 14 ng/g dust, respectively. In addition, the observed high prevalence of dampness or mold problems in the day-care centers indicated that dampness was very common in this subtropical region. We found a significant relationship between dampness and work-related sick building syndrome in the day-care-center workers. Furthermore, concentrations of fungi were lower in the day-care centers equipped with air conditioners/air cleaners than in centers that lacked such equipment. Also, Aspergillus was associated strongly with work-related sick building syndrome in the day-care-center workers.
在本研究中，我们调查了台北28家日托中心的264名护理人员的室内空气质量和呼吸道疾病症状。室内和室外细菌的几何平均浓度分别为每立方米空气中735个菌落形成单位（CFU/m³）和384 CFU/m³。此外，室内和室外真菌的几何平均浓度分别为1212 CFU/m³和1032 CFU/m³。在室内和室外均发现了最常见的曲霉属、枝孢属和青霉属微真菌。屋尘螨过敏原Der p I和Der p V的几何平均浓度分别为每克灰尘58纳克和14纳克。此外，日托中心潮湿或发霉问题的高发生率表明，在这个亚热带地区潮湿现象非常普遍。我们发现日托中心工作人员的潮湿与工作相关的病态建筑综合征之间存在显著关联。此外，配备空调/空气净化器的日托中心的真菌浓度低于没有此类设备的中心。而且，曲霉与日托中心工作人员的工作相关病态建筑综合征密切相关。
