英文摘要 | Teachers and students work and study on campus for a long time, so the campus's air quality needs attention. This study focuses on the microbial pollution in the air of campus from the beginning to the end of the haze. The total suspended particulate sampler and high-throughput sequencing were used to analyze the concentration and diversity of microorganisms. Then, the concentrations of particles and ions were calculated and compared with normal weather. PICRUSt software was used to predict functional gene composition. The spreading character of haze was described by Principal Component Analysis and The Hybrid Single-Particle Lagrangian Integrated Trajectory Model. The hazard index was calculated to assess the health risk of haze. The results showed that the average concentration of bacteria (88 CFU/m(3)) was higher during the haze than in normal weather (59 CFU/m(3)). Bacterial concentration in the air is the highest at the later stage. The diversity of bacteria during the haze was 1.6 times that in normal weather. The main intestinal bacteria during haze are Bacteroides. The haze did not change the functional genes of bacteria. Fungi changed slightly in haze weather compared with normal weather. The average concentration of particulate matter (508.72 mu g/m(3)) during haze weather was higher than that in normal weather (291.67 mu g/m(3)). The proportion of primary ions in the air decreased during the haze. The relative humidity is an essential factor affecting bioaerosols. One hour after the haze passed through the sampling point, the diffusion range was about 233.35km(2). The risk of bioaerosol for men is higher than that for women. Therefore, personal protection should be strengthened during the haze. |
