英文摘要	Studies on microbial populations in near-ground aerosols during fog-haze days could help enhance our knowledge concerning the relationship between fog-haze and human health. In this study, microbial populations in aerosols near-ground during a fog-haze event in Beijing were analyzed using clone library methods. Results showed that the bacterial diversity in aerosols during fog-haze days was lower than that after fog-haze days. Proteobacteria alone and Proteobacteria with Firmicutes were respectively detected in 1.5 and 20 m aerosols during fog-haze days. In addition to Proteobacteria and Firmicutes, Bacteroidetes alone and Acidobacteria with Verrucomicrobia were respectively found in aerosols at 20 and 1.5 m after fog-haze days. The fungal species observed during fog-haze days were completely different from those detected after fog-haze days. Ascomycota and Basidiomycota were respectively detected during and after fog-haze days. The distribution of microbial diversity in aerosols exhibited meteorological and site-associated variations. The same potential pathogenic microorganisms were detected at different heights during fog-haze days. This study on the characteristics of microbial population in aerosols could provide a comprehensive understanding of the factors causing the harmful effects of particles on humans during fog-haze days.
