The Variations of Fungal Community Structure and Composition During Haze Events in Beijing, China

Abstract
Haze events have become a severe air pollution problem in Beijing, since 2013. Airborne microbes are important components of particulate matter, which may threaten human healthy. However, the variations of fungi in haze events remain unclear. In this study, we characterized the airborne fungal community structure and composition in response to nine haze events that occurred between October 1, 2015, and January 5, 2016. We also explored the key environmental factors that significantly affect airborne fungal community structure. Our results indicated that although airborne fungal alpha diversity and community structure were stable during haze events, particulate matter, gaseous pollutants and relative humidity still had obvious effect on airborne fungal community structure. Meanwhile, we also found that Cladosporium, Aspergillus, Cordyceps and Torulawereenriched on haze days. Our study extends the knowledge about the airborne fungal characteristics in haze events.
