| 英文摘要 | Landfill sites are regarded as prominent sources of bioaerosols for the surrounding atmo-sphere. The present study focused on the emission of airborne bacteria and fungi in four seasons of a sanitary landfill site. The main species found in bioaerosols were assayed using high-throughput sequencing. The SourceTracker method was utilized to identify the sources of the bioaerosols present at the boundary of the landfill site. Furthermore, the health conse-quences of the exposure to bioaerosols were evaluated based on the average daily dose rates. Results showed that the concentrations of airborne bacteria in the operation area (OPA) and the leakage treatment area (LTA) were in the range of (4684 +/- 477)-(10883 +/- 1395) CFU/m(3) and (3179 +/- 453)-(9051 +/- 738) CFU/m(3), respectively. The average emission levels of fungal aerosols were 4026 CFU/m(3) for OPA and 1295 CFU/m3 for LTA. The landfill site received the maximum bioaerosol load during summer and the minimum during winter. Approximately 41.39%- 86.24% of theairborne bacteria hada particle sizeof 1.1 to4.7 mu m, whereas 48.27%-66.45% of the airborne fungi had a particle size of more than 4.7 mu m. Bacillus sp., Brevibacillus sp., and Paenibacillus sp. were abundant in the bacterial population, whereas Penicillium sp. and Aspergillus sp. dominated the fungal population. Bioaerosols released from the working area and treatment of leachate were the two main sources that emerged in the surrounding air of the landfill site boundary. The exposure risks during summer and autumn were higher than those in spring and winter. (c) 2021 The Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.
