Bioaerosol Emissions From Municipal Solid Waste Transfer Points: Seasonal Characteristics, Quantitative Health Risks, and the Role of PPE Protection

of E. coli and S. aureus bioaerosol for all exposure scenarios in the summer was 1.66-2.18 and 1.45-1.63 times, respectively, higher than that in the autumn. For all exposure populations, the DB with PPE was approximately one order of magnitude lower than that without PPE. Exposure concentration to the DB without PPE was the first predominant input parameter for all exposure scenarios. Sensitivity analysis recommends using PPE as a key mitigation strategy to manage bioaerosol health risks during different seasons and worker roles. This research delivered novel data and provided guidelines for controlling the bioaerosol emission health risks from MSW transfer points.
