Bioaerosol exposure is a significant health risk for workers in solid waste disposal facilities, yet data on their seasonal variability and exposure risks remain limited. This study comprehensively assesses bacterial and fungal bioaerosols at a Solid Waste Disposal Facility in Istanbul, focusing on critical zones such as the landfill, biomethanization unit, and landfill leachate treatment plant. Seasonal air samples were collected using an Anderson cascade impactor, and the results showed that bioaerosol concentrations were highest in the landfill area, equalization tank, and bioprocess tanks during spring. Indoor bacterial bioaerosols consistently exceeded permissible levels throughout the year. Meteorological factors significantly influence bioaerosol levels, including ventilation coefficient and boundary layer height. Morphological analysis provided insights into various bacterial and fungal species. Employees' exposure risks were assessed using time-weighted average concentrations for the first time, and employees' individual differences provided realistic hazard quotient values. A questionnaire evaluating employees' attitudes toward biological risks and personal protective equipment usage emphasized gaps in awareness and behaviour. These findings highlighted the need for risk management strategies, such as improved ventilation systems, optimized work schedules, and training programs to promote consistent personal protective equipment use, especially N95 masks. The results contribute to developing measures to minimize bioaerosol exposure and protect employees' health in similar facilities worldwide.
