亞熱帶地區室內的生物性氣膠空氣品質

Microbiological Indoor Air Quality in Subtropical Areas

許多的研究發現，空氣中的真菌直接或間接地與呼吸系統方面疾病有關，而台灣的氣候條件相當適合於真菌生長。本研究於81年5月及6月以二階生物氣膠衝擊器，在台北地區六個家戶進行真菌採樣，採樣地點包括室外、客廳、臥室、廚房及浴室。結果發現真菌平均濃度都在1000 CFU/m3以上（420-4200 CFU/m3），吸入性真菌佔了總數的百分之八十，而且主要出現的真菌菌屬包括Cladosporium、Penicillium、Yeast及Aspergillus。另一方面除了浴室外，室外真菌濃度與室內（客廳、臥室及廚房）真菌濃度有顯著的相關性。

In Taiwan, a subtropical country, bioaerosols are regarded to be quick to grow, because of high relative humidity and high temperature all year around. Field investigations of microbiological indoor air quality were performed in six apartments in the Taipei area. Two-stage Andersen viable impactors were used to determined the concentration, genus, and respirable fraction of fungi indoors and outdoors. The fungi characteristics in living rooms, bedrooms, kitchens, bathrooms, and outdoors were compared. The concentration of indoor and outdoor fungi in different locations of the six apartments were found to vary widely. The geometric mean concentrations of indoor and outdoor fungi were higher than 1000 CFU/m3. Moreover, more than 80% of indoor and outdoor fungi were observed to be respirable. In addition, the ratios of indoor to outdoor fungi sources. In some homes, the concentrations of the asthma-related fungi genus, Aspergillus, Penicillium, and Cladosporium, were found to exceed 500 CFU/m3.
