Occupational Bioaerosol Exposure in Academic Libraries and Its Implications For Respiratory Health

Abstract

University libraries are enclosed indoor workplaces where librarians may experience repeated exposure to airborne bioaerosols, particularly fungal spores, arising from book handling, dust accumulation, and limited air circulation in certain zones. While indoor air quality (IAQ) has received growing attention, microbial exposure in library settings remains underexplored, despite its potential contribution to respiratory discomfort and occupational health concerns. This study aimed to quantify airborne fungal concentrations across selected library work areas and examine their association with respiratory symptoms among librarians.
