2025-10-03UFP-Advisory-Group-Meeting-2025.10
Meeting minutes from the UFP Advisory Group discussing research priorities for ultrafine particle health effects, mitigation strategies, and exposure reduction in aviation-impacted communities. Participants included University of Washington researchers, public health officials, school district representatives, and community leaders focusing on air quality and health impacts near Sea-Tac Airport. -
2025-10-01Impacts of Aviation Emissions on Air Quality Near Hanscom Field, Bedford, Massachusetts – Results of a Two-Season Monitoring Campaign
A comprehensive study measuring ultrafine particles, lead, and other air pollutants from aviation emissions at Hanscom Field across four surrounding Massachusetts towns. The study found that UFP concentrations were up to two-fold higher at downwind sites and often exceeded WHO guidelines, with the highest impacts in Bedford and Lexington. -

A rendered illustration showing Zunum Aero hybrid-electric aircraft (registration N713TZ visible on fuselage) flying over the Seattle metro area, with Lake Washington, downtown Seattle skyline, and Mount Rainier visible in the background. Three aircraft of varying sizes are depicted, consistent with Zunum Aero's regional electric aviation concept promotional materials. -
2025-08-11Impacts of Aviation Emissions on Community Health
Researchers from the University of Washington presented findings to King County's Airport Round Table Advisory Committee showing that aviation emissions pose significant public health risks to nearby communities. Airports account for 70% of airborne lead emissions in King County, primarily from piston-engine aircraft burning leaded aviation gasoline, and multiple studies link living close to such airports with elevated blood lead levels in children. The presentation also highlighted broader health harms from aviation pollutants—including ultrafine particles and nitrogen oxides—affecting neurological, cardiovascular, and respiratory health. -

Impacts of Aviation Emissions on Community Health
Presentation by UW Center for Environmental Health Equity (CEHE) team — Elena Austin, Edmund Seto, Timothy Larson, Ningrui Liu, and Janice North (DEOHS/Epidemiology) — to the Airport Round Table Advisory Committee on August 11, 2025. Covers aviation air pollution health impacts in King County including leaded aviation gasoline (avgas), ultrafine particles, nitrogen oxides, and Jet -
2025-07-282025/2026 StART Shared Federal Aircraft Noise & Emissions Policy Priorities
The StART (Sea-Tac Airport Roundtable) coalition has outlined its 2025/2026 federal policy priorities aimed at reducing aircraft noise and air emissions around Seattle-Tacoma International Airport. Key goals include passing new legislation to fund failed noise insulation repairs and expand EPA authority over aviation emissions, securing funding for sustainable aviation fuel programs, and pushing the FAA to fully implement noise and emissions provisions from the 2024 FAA Reauthorization Act that have stalled under new federal leadership. The group also plans a Washington, D.C. advocacy trip in spring 2026 to advance these priorities with Congressional and Administration officials. -
