The fungal spore concentration (FSC) in the air poses a risk for human health. This work studied the FSC in university libraries and how it is affected by environmental factors. A total of 347 samples were obtained using a Microbio MB2(®) Aerosol Sampler. The wind speed (WS), cross wind (CW), temperature (T), relative humidity (HR), barometric pressure (BP) and dew point (DP) were recorded using a Kestrel(®) 4500 weather station. The median indoor/outdoor FSC was 360/1230 CFU m(-3). FSC correlated inversely with BP, HR and DP; and positively with WS and CW; whereas T showed negative or positive correlation with FSC, depending on the region or sampling time. Eleven fungal genera were found and the dominant isolates were identified as Aspergillus niger, Aspergillus tamarii and Aspergillus oryzae. All fungi identified are known to be allergenic. It was concluded that environmental variables can influence the air FSC in different ways.
空气中的真菌孢子浓度（FSC）对人类健康构成风险。这项研究调查了大学图书馆中的真菌孢子浓度及其受环境因素的影响。使用Microbio MB2(®)气溶胶采样器共采集了347个样本。使用Kestrel(®) 4500气象站记录风速（WS）、侧风（CW）、温度（T）、相对湿度（HR）、气压（BP）和露点（DP）。室内/室外真菌孢子浓度的中位数分别为360/1230 CFU m(-3)。真菌孢子浓度与气压、相对湿度和露点呈负相关；与风速和侧风呈正相关；而温度与真菌孢子浓度的相关性则取决于区域或采样时间，可能呈负相关或正相关。研究共发现了11个真菌属，主要分离株被鉴定为黑曲霉、塔宾曲霉和米曲霉。所有鉴定出的真菌均具有致敏性。研究得出结论，环境变量能够以不同方式影响空气中的真菌孢子浓度。
