四川大学新校区空气卫生质量调查与评价

Investigation and Assessment on Air in New College Campus in Sichuan University

目的研究高校新校区学生主要活动场所空气微生物污染状况,评价学生活动场所的空气质量。方法采用平板沉降法,于夏季早、晚分别检测四川大学江安新校区6个不同环境空气中的细菌、霉菌和嗜血链球菌数。结果除浴室外,新校区内不同环境空气中平均细菌数都达到国家非污染空气的标准,教室、计算机房、一餐厅、女生宿舍空气均属于清洁空气;男生宿舍、阅览室和二餐厅则属于普通空气;浴室属于重污染空气。学生宿舍、二餐厅霉菌数稍高于其他环境,以浴室的空气中霉菌数最多。各测试点的嗜血链球菌数均低于相关标准。结论四川大学江安新校区除极少数环境需要加强管理外,主要学生活动场所的空气非常清洁。
