We examined 12,026 fungal air samples (9,619 indoor samples and 2,407 outdoor samples) from 1,717 buildings located across the United States; these samples were collected during indoor air quality investigations performed from 1996 to 1998. For all buildings, both indoor and outdoor air samples were collected with an Andersen N6 sampler. The culturable airborne fungal concentrations in indoor air were lower than those in outdoor air. The fungal levels were highest in the fall and summer and lowest in the winter and spring. Geographically, the highest fungal levels were found in the Southwest, Far West, and Southeast. The most common culturable airborne fungi, both indoors and outdoors and in all seasons and regions, were Cladosporium, Penicillium, nonsporulating fungi, and Aspergillus. Stachybotrys chartarum was identified in the indoor air in 6% of the buildings studied and in the outdoor air of 1% of the buildings studied. This study provides industrial hygienists, allergists, and other public health practitioners with comparative information on common culturable airborne fungi in the United States. This is the largest study of airborne indoor and outdoor fungal species and concentrations conducted with a standardized protocol to date.
我们检测了来自美国各地1717栋建筑的12026份真菌空气样本（9619份室内样本和2407份室外样本）；这些样本是在1996年至1998年进行的室内空气质量调查期间采集的。对于所有建筑，室内和室外空气样本均使用安德森N6采样器采集。室内空气中可培养的空气传播真菌浓度低于室外空气。真菌水平在秋季和夏季最高，在冬季和春季最低。从地理上看，真菌水平最高的地区是西南部、远西部和东南部。在所有季节和地区，室内和室外最常见的可培养空气传播真菌是枝孢菌、青霉菌、无孢子真菌和曲霉菌。在所研究的6%的建筑室内空气中以及1%的建筑室外空气中鉴定出了黑曲霉。这项研究为工业卫生学家、过敏症专科医生和其他公共卫生从业者提供了关于美国常见可培养空气传播真菌的比较信息。这是迄今为止采用标准化方案对空气传播的室内和室外真菌种类及浓度进行的最大规模研究。
