2016-12-27Ultrafine Particles Near Airports
Presentation by Professor Timothy Larson, University of Washington Department of Civil and Environmental Engineering (CEE/UWDEOHS), on ultrafine particles (UFPs) near airports, delivered December 2016. Covers UFP characteristics, size ranges (sub-100nm), and comparison to diesel smoke, combustion products, tobacco smoke, carbon black, and other particulates. Collaborative research with USC researchers Scott Fruin and Neelakshi Hudda, and -
2016-12-01Ultrafine Particles Near Airports
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. -

1999-05-20Sea-Tac Airport spatial nitrogen dioxide study final report
A 1999 University of Washington study measured nitrogen dioxide (NO2) levels around Seattle-Tacoma International Airport to determine whether aircraft operations were harming local air quality. Researchers found that NO2 levels at all monitoring sites remained well below federal safety standards, and that regional conditions and nearby freeways — not aircraft — were the primary drivers of local pollution. The study concluded that airport operations had only a small, difficult-to-isolate effect on community NO2 levels, estimated at less than 7 parts per billion above background levels.
