Particle Resuspension: From Indoor and Outdoor Sources to the Human Receptor

Abstract Number: 19 Working Group: Invited by Conference Chair
Abstract Particle resuspension is a major contributor to both indoor and outdoor aerosols. While we benefit from decades of research in this field, there has recently been more attention on particle resuspension due to its role in exposure to bioaerosols that impact human health. This presentation will address particle resuspension from source to receptor, including adhesion and detachment mechanisms, primary factors affecting resuspension, and the role of resuspension in human exposure to aerosols. Current models for resuspension, validated by both wind tunnel and bulk air experiments, will be discussed along with best estimates for resuspension source emission terms and intake fractions for inhalation exposure. The work has many applications, including controlling particle adhesion and removal in the manufacturing processes for the semiconductor, xerographic, and pharmaceutical industries, understanding residential exposures to pollutants associated with indoor dust from resuspension via human activity, and protecting soldiers in the field from exposure to chemical and biological agents.
