摘要

Exposure to bioaerosols poses important health effects on occupants. To elucidateseasonal and room variations of household airborne bacteria, this study investigated30 residential homes during summer and winter throughout Nanjing, SoutheastChina, with a humid subtropical climate. Culturing and 16S rDNA sequencing methodswere combined in this study. Results showed that the community structure andcomposition in the same season but different homes show similarity, however, they inthe same home but in different seasons show a huge difference, with Sphingomonas(25.3%), Clostridium (14.8%), and Pseudomonas (7.6%) being the dominant bacteria insummer, and Pseudomonas (57.1%) was dominant bacteria in winter. Culturable concentrationsof bacteria were also significantly higher in summer (854 ± 425 CFU/m~3)than in winter (231 ± 175 CFU/m~3), but difference by home or room was relativelyminor. More than 80% of culturable bacteria (<4.7 μm) could penetrate into lowerrespiratory tract. The seasonal variations of bacterial community and concentrationswere closely associated with seasonal variations of temperature, humidity, and PM_(2.5).Higher concentrations and larger sizes were observed in the bathroom and kitchen,typically with higher humidity than other rooms.
