Strong evidence suggests that clothing serves as a reservoir of chemical pollutants and particles, including bioaerosols, which may have health significance. However, little is known about the role that clothing may play in exposing people to airborne chemicals and particles. This project aims to better understand the role of clothing in exposure to gaseous species and particulate matter including bioaerosols. The results of this project will add knowledge and understanding of the role of clothing in contributing to primary and secondary exposure routes and could ultimately help strengthen exposure and risk assessments. The knowledge gained could also prove worthwhile for characterizing interventions to mitigate the transfer of airborne pollutants from clothing to the respiratory tract.
