2025-10-03UFP-Advisory-Group-Meeting-2025.10
★Advisory group meeting presentation focused on urban ultrafine particles, likely related to aviation emissions and air quality impacts on airport communities. The meeting appears to be part of ongoing research or policy discussions regarding particulate matter from aircraft operations. -
2025-01-23HB 1303 Bill Analysis – Increasing environmental justice by improving government decisions
★Washington State House Bill 1303 proposes strengthening environmental justice by adding new requirements to the State Environmental Policy Act (SEPA) review process, requiring environmental justice impact statements for projects in vulnerable or overburdened communities. The bill also prohibits state and local air authorities from issuing certain construction approvals for new air pollution sources in those same communities. Note: This bill focuses on statewide environmental permitting and community health protections, and does not directly address Sea-Tac Airport noise policy. -
2022-08-20The Effect of Occupational Exposures to Aircraft Ultrafine Particles on Acute Cardiorespiratory Health, and Control Using Personal Protective Equipment
★A University of Washington thesis by Mariah Dittmore investigates whether short-term exposure to ultrafine particles from aircraft engines causes measurable cardiorespiratory harm at concentrations found in surrounding communities, and whether personal protective equipment can reduce that harm. The research builds on a 2018 Los Angeles study that linked walking near aircraft pollution to elevated blood inflammation markers, while noting that roadway traffic posed its own distinct respiratory risks. The findings are relevant to policy discussions around Seattle-Tacoma International Airport and the health of workers and residents exposed to aircraft emissions. -
STCP Air Quality Measurement Sites Near Sea-Tac Airport
A map from the Sea-Tac Communities Plan (document reference POS 690, page 5.1.0) showing seven air quality measurement sites near Seattle-Tacoma International Airport. Sites 1–4 are ESL sites and sites 5–7 are Puget Sound Air Pollution Control Agency sites; the plan was sponsored by the Port of Seattle and King County. -
PSCAA AQI Index
An Air Quality Index (AQI) reference table published by the Puget Sound Clean Air Agency, showing four levels of concern (Good 0-50, Moderate 51-100, Unhealthy for Sensitive Groups 101-150, and Unhealthy 151-200) with corresponding descriptions and public health recommendations. The agency's logo is visible in the lower right corner. -
2025-12-012025 Report: Overburdened Communities Highly Impacted by Air Pollution
A report by the Washington State Department of Ecology’s Air Quality Program examining overburdened communities that are highly impacted by air pollution. The document includes publication information, contact details for regional offices, and ADA accessibility information. -
2025-11-07Ultrafine particles and black carbon concentrations and determinants in aircraft cabins of a French airline: Paris-aircraft study
A French study measured ultrafine particle (UFP) and black carbon (BC) air pollution inside aircraft cabins across 16 European commercial flights, finding average concentrations of 9,122 particles/cm³ for UFP and 207 ng/m³ for BC. Pollution levels were highest during ground phases such as boarding and taxiing, then dropped during flight, with outdoor airport air identified as the primary source of cabin air pollution. These findings suggest that airport ambient air quality plays a greater role in passenger exposure than in-flight sources. -

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. -
2025-10-03Urban Ultrafine Particles – Advisory Group Meeting
The University of Washington held an Advisory Group Meeting on October 3, 2025, focused on urban ultrafine particles (nano-particles) and their sources, including aviation-related emissions near areas like Sea-Tac Airport. The meeting aimed to foster dialogue, address knowledge gaps from the MOV-UP study, identify priority research questions, and guide scientific research on air quality monitoring. Advisors were asked to provide feedback on study design and methodology, with a time commitment including annual meetings and optional review of study outputs.
