Human walking influences indoor air quality mainly by resuspending dust particles settled on the floor. This study characterized walking‐induced particle resuspension as a function of flooring type, relative humidity (RH), surface dust loading, and particle size using a consistent resuspension mechanism. Five types of flooring, including hardwood, vinyl, high‐density cut pile carpet, low‐density cut...
Abstract The role of human occupancy as a source of indoor biological aerosols is poorly understood. Size‐resolved concentrations of total and biological particles in indoor air were quantified in a classroom under occupied and vacant conditions. Per‐occupant emission rates were estimated through a mass‐balance modeling approach, and the microbial diversity of indoor and outdoor air during occupancy...
