安庆师范学院菱湖校区主要功能区空气微生物污染调查与分析

Investigation and Analysis of Microbe Pollution in Different Environmental Function Districts of the Campus of Anqing Teachers College

采用撞击法和自然沉降法分别对安庆师范学院菱湖校区主要场所空气微生物(细菌)总数进行监测,对照相关评价指标,作出空气微生物污染状况评价,并对两种方法的捕获效果进行了比较,撞击法和自然沉降法测得空气细菌总数间存在显著的正的线性相关关系(r=0.719,p<0.05);撞击法比自然沉降法捕获效率更高;校内除男生寝室属于轻微污染外,其他主要功能区空气属于清洁或较清洁,空气质量较好。

The sum of atmosphere bacteria in main environmental function districts of the campus of Anqing Teachers＇ College is tested using impacting method and sedimentation method,the situation of air microorganism pollution is evaluated on the basis of the correlative standards.Apart from those,the effects of the two air sampling methods are contrasted.We can draw the following conclusions.There is a significant correlation between the bacterial counts collected by sedimentation and impacting methods（（r=0.719,p0.05）,Compared with sedimentation method,the impacting method has better efficiency when we collect bacteria in the air.Except air quality of male dormitory is slightly polluted,air quality of other main function districts is clear or comparative clear level.
