目的研究空气中微生物的分布规律,为空气质量监测提供依据。方法采用平皿自然沉降法进行空气采样,培养后计数菌落。结果学校与医院、学校与餐饮娱乐场所空气微生物含量比较差异有统计学意义(P<0.01或P<0.05),医院和KTV在真菌含量上差异有统计学意义(P<0.05);学校下午真菌含量与上午相比差异有统计学意义(P<0.05),医院上午和下午、上午和晚上、下午和晚上的真菌含量差异都存在有统计学意义(P<0.01或P<0.05);不同海拔中,山脚与山腰、山顶与山腰真菌含量上差异有统计学意义(P<0.01)。结论不同地点、不同时间段、不同海拔空气中微生物各有差异,空气微生物与空气质量相关。其中学校、医院、餐馆都存在一定的空气微生物感染的隐患。
Objective To study the distribution of microorganisms in air and provide the basis for air quality monitoring. Methods The natural sedimentation method was used for air sampling and the colonies were counted after culture. Results There was significant difference in air microbes content between schools and hospitals, schools and dining and entertainment venues (P <0.01 or P <0.05), there was significant difference in fungal contents between hospitals and KTV (P <0.05) (P <0.05). There were significant differences in the fungal contents in the morning and afternoon, morning and evening, afternoon and evening in the hospital (P <0.01 or P <0.05) (P <0.01). There was a significant difference in the fungal contents between the mountainside and mountainside, the mountaintop and the mountainside (P <0.01). Conclusion There are differences in airborne microorganisms in different locations, different time periods and different altitudes, and airborne microbes are related to air quality. One of the schools, hospitals, restaurants there are some hidden dangers of airborne microorganisms.
