摘要
目的研究校园室内空气微生物的污染情况。方法于2004年4—5月用柯赫沉降法,在早上、中午和晚上(早上6:30—7:30、中午11:30—12:30、晚上18:00—19:00)3个时间段,对聊城大学校园室内(学生宿舍、校园餐厅、校阅览室、校园网吧和校医院各设6、12、9、5、6个采样点)空气微生物(细菌、霉菌)进行采样,每个采样点重复采样3次。结果校园室内空气细菌平均含量为2.39×103cfu/m3,空气质量为细菌较清洁水平。校园网吧空气细菌的含量较高(7.99×103cfu/m3),达轻度污染水平。校园室内空气霉菌平均含量为0.62×103cfu/m3,空气质量为霉菌较清洁水平。校园餐厅的空气霉菌含量较高(1.52×103cfu/m3),达轻度污染水平。各采样地点不同时段空气细菌、霉菌含量比较,差异无统计学意义(P>0.05)。结论聊城大学校园室内空气质量为细菌、霉菌较清洁水平。
Objective To understand the microorganism pollution in the indoor air in the campus of Liaocheng University. Methods In April and May, 2004, the content of airborne microbes in the indoor air in Liaocheng University campus was determined by the gravity plate method. Results The average content of bacteria in the indoor air was 2.39×10^3cfu/m^3, the average content of mildew was 0.62×10^3cfu/m^3. The predominant microorganism in the internet bars in the campus was bacteria. Conclusion In general, the indoor air quality in Liaocheng University campus is at comparative clear level.
