"Exposure to airborne particles is detrimental to human health and indoor exposures dominate total exposures for most people. Also, the release of aerosolized chemical and biological agents within or near a building can lead to exposures of building occupants to hazardous agents and costly building remediation. Researchers in the Indoor Environment Department are using experimental and modeling techniques to evaluate the transport and deposition of particles in the indoor environment. This includes evaluations of particle deposition at cracks in building envelopes, in ventilation systems and to indoor surfaces, as well as the resuspension and tracking of previously deposited particles by human activities. This research provides needed information for improving exposure evaluations of ambient particles and hazardous aerosols. -- Air flow and pollutant transport group
