This December 2016 presentation by University of Washington Professor Tim Larson examines ultrafine particles (UFPs) — tiny airborne particles smaller than 0.1 micrometers — found near airports, with a focus on emissions from aircraft and other combustion sources. Conducted in collaboration with researchers from UW and USC, the study explores how these microscopic particles, which are far smaller than diesel smoke or tobacco smoke particles, may pose environmental and health concerns for communities near airports like Sea-Tac. The research provides scientific context for understanding air quality impacts associated with airport operations.Open full document
Notes
Presentation by Professor Tim Larson (CEE, University of Washington) on ultrafine particles (UFPs) near airports, delivered December 2016. Covers what UFPs are, their size range (sub-100nm), and sources including diesel smoke, combustion products, tobacco smoke, and aviation emissions. Collaborative research between UW (DEOHS) and USC researchers Scott Fruin and Neelakshi Hudda. References ACI EUROPE UFP Study 2012. Relevant to airport air quality, UFP exposure, and community health impacts near Sea-Tac Airport.
