| Abstract: | Presents the indoor and outdoor airborne fungal concentration correlation and particle size of a student office in a university.The results show that the variation range of indoor airborne fungal concentration is 1698to 4429 cfu/m3,and the outdoor concentration range is3569 to 29452 cfu/m3,with the highest values at 12:00.The ratio of indoor and outdoor airborne fungal concentration is below 1,and Spearman correlation analysis shows a significant positive correlation between indoor and outdoor airborne fungi,and linear regression analysis shows that outdoor airborne fungal concentration is a significant factor affecting indoor fungal concentration,representing outdoor airborne fungi being the main source.The indoor fungal concentration is significantly positively correlated with the number of indoor occupants.Indoor and outdoor airborne fungi gradually increase from stage Ⅰ to stage Ⅳ,and then decrease from stage Ⅴ to stage Ⅵ,with the highest value at stage Ⅳ.More than 85.0%of the particle size of indoor and outdoor airborne fungi can reach people's lower respiratory tract. |
