| 摘要 | Both of indoor and outdoor air pollution levels have considerable negative impacts on human health while people spend over 80% of their time indoors. The main purpose of this paper is to investigate the variability of pollutants on the university campus and the exposure of staff and students to pollutants in buildings and outdoors on campus. Indoor/outdoor (I/O) particulate mass concentration (PM10, PM2.5 and PM1) and gas concentration (CO2, CO, NO) were measured with QARPEDIEM miniature sensors in the library with mechanical ventilation. The measurement took place during February 2019 on university campus, which belongs to the Université de Lille, in France. First of all, the daily variations and statistical characteristics of particle and gas indoor and outdoor concentration were displayed, which shows higher air pollutants indoor levels during weekdays than weekends. Then, the correlation analysis of CO2 indoor levels and human presence in the library and the particle mass concentration difference between a small room and balcony in library were present, which indicates particle indoor concentration changing with the number of people occupied. Moreover, the I/O ratio of particles and CO2 as well as air exchange rate of the library were calculated, and the results show that the coarse particles indoor concentration was associated with indoor resuspension activities. |
