摘要 :高校图书馆人员流动频繁 ,且储藏大量珍贵的图书文献 ,易形成真菌气溶胶污染.真菌气溶胶污染不仅增加了人体
患哮喘和呼吸道疾病的风险 ,还会加速纸张发霉减少图书的储藏年限.本文以西安某高校图书馆为研究对象 ,分析了真菌
气溶胶的浓度 、粒径等分布特征 ,对典型馆室颗粒物浓度进行对比 ,并分析了不同环境因素与真菌气溶胶的相关性.结果
表明 ,测试期间图书馆四个典型馆室真菌气溶胶平均浓度为 743 CFU/m 3,室内颗粒物平均浓度为大小为 49. 8 “g/n? ,并
且室内外颗粒物浓度比 (I/O) 平均为 0. 93. 真菌气溶胶粒径范围主要集中在 2. 1-3. 3 “m和 1.1-2.1 真菌气溶胶浓
度与颗粒物浓度 、相对湿度 、人员数量和书籍年代之间存在正相关关系 ,相关系数分别为 0.484 、0.240 、0.492 、0. 326,
而与温度之间呈负相关性 ,相关系数为 一0.33 &

Abstract : University library staff are frequent and a large number of precious books and documents are stored,
which is easy to form fungal aerosol pollution ・ The fungal aerosol pollution not only increases the risk of asthma
and respiratory diseases in the human body, but also accelerates the mildew of the paper and reduces the storage
period of the book. This paper takes a university library in Xi'an as the research object, analyzes the distribution
characteristics of fungal aerosol concentration and particle size, compares the concentration of typical chamber
particles , and analyzes the correlation between d辻ferent environmental factors and fungal aerosols ・ The results
showed that the mean concentration of fungal aerosols in the four typical chambers of the library during the test
were 743 CFU/m 3, the mean concentration of indoor particulate matter was 49. 8 pig/m 3 , and the mean indoor-to-
foreign particulate matter concentration ratio (I/O) was 0. 93. The fungal aerosol particle size range is mainly
concentrated in 2・ 1 to 3. 3 #m and 1・ 1 to 2. 1 pm ・ There was a positive c
