In order to deeply analyze the pollution situation, distribution characteristics and exposure level of microbial aerosol in different functional buildings, the concentration, particle size distribution and resident exposure level of bacterial aerosol in different functional places of hospitals were studied in this paper. The results show that: 1) There are harmful environmental exposure and environmental health risks in the standardized training of residents in China, which need to be paid enough attention to improve their occupational environment. 2) the concentration level of indoor bacterial aerosol in various places of hospital in winter is outpatient hall > nurse station > doctor’s office > outdoor > general ward. 3) The median diameter of indoor bacterial aerosols in hospital buildings is smaller than that of outdoor ones, and there are differences in particle size distribution of indoor bacterial aerosols in different types of places. When indoor pollution sources are strong or indoor ventilation is poor, the particle size distribution characteristics of bacterial aerosols are mainly affected by indoor pollution sources.
