校园空气微生物和悬浮物污染评价及相关性分析

在对广西师范大学育才校区教学区、宿舍区、运动场和交通区大气微生物和总悬浮颗粒物(TSP)进行监测的基础上,评价与分析了育才校区大气污染状况。依照中国科学院生态中心推荐使用的空气微生物评价标准,育才校区大气微生物污染轻微,其中交通区和运动场大气微生物含量相对较高,但都能达到清洁空气的标准;大气总悬浮颗粒物污染下午较严重,多数测定值超过了国家环境空气质量标准中的二级标准限值,而上午的测定值相对较低;四个功能区中TSP浓度值为交通区>运动场>教学区>宿舍区。上午空气中TSP浓度与细菌总数具有显著相关性,与霉菌总数相关关系不显著;下午TSP测定值与空气中细菌总数和霉菌总数的相关关系均不显著;校园空气中细菌总数和霉菌总数为极显著相关。

Air Micro-organisms and Suspended Particles Pollution Evaluation and Correlation Analysis on Campus

Based on the monitoring of atmospheric total suspended particles and micro-organisms of teaching areas, living quarters, sports fields and traffic areas of campus Yucai of Guangxi Normal University, this article evaluated and analysis of its situation of air pollution. According to the standards of air microbiological evaluation which is recommended by the Ecological Center of Chinese Academy of Sciences, the atmospheric microbial contamination is not so serious, although the traffic areas and sports fields content more micro-organisms than other areas, but they still can achieve to clean air standards; atmospheric pollution of the total suspended particulate matter is more serious in the afternoon and most over the grade two standard limits of The People's Republic of China ambient air quality standards, but all of The measured value was lower in the morning for these four functional areas, the atmospheric total suspended particles of the traffic zone is more than sports fields,the teaching zone of it is in the third and the living quarters is the least. the atmospheric total suspended particles have significant correlation with the total number of bacteria but not with the mold in the morning ;in the afternoon,it have no significant correlation with the number of bacteria as well as the mold. But the number of bacteria and the mold of campus have a very significant relation.
