UW study shows Seattle’s historically redlined communities have worse air quality
By Isabella Breda Seattle Times staff reporter As Seattleites awoke to a hazy concoction of wildfire and Fourth of July firework smoke Wednesday morning, a new study dropped, revealing that some neighborhoods in the city are regularly subject to worse air pollution, reflective of historic racist policies. Those neighborhoods, according to research published Wednesday from the University of Washington, -
MOV-UP report vehicle — UCAR atmospheric monitoring Prius
A white Toyota Prius Hybrid bearing the UCAR (University Corporation for Atmospheric Research) logo on its door, equipped with roof-mounted scientific instrumentation including sensors and probes. The vehicle is numbered 144 and appears to be configured for atmospheric or environmental data collection fieldwork. -
2022-10-05Indoor air quality intervention in schools: effectiveness of a portable hepa filter deployment in five schools impacted by roadway and aircraft pollution sources
A study examining the effectiveness of portable HEPA filters in reducing ultrafine particles (UFPs) from aircraft and traffic sources in five schools near Sea-Tac International Airport. The research found that HEPA cleaners significantly reduced indoor UFP concentrations to one-half to one-tenth of outdoor levels. -

UWDEOHS-particle deposition
An educational infographic titled 'Particle Size & Lung Deposition' illustrating how airborne particles of different sizes deposit in various regions of the respiratory tract: particles >10 μm in the nose and throat, 2.5–10 μm in the windpipe and large airways, 0.1–2.5 μm in small airways, and <0.1 μm in small airways and alveolar sacs. The diagram includes an anatomical illustration of the human respiratory system with a magnified inset of alveolar sacs. -
UWDEOHS-PM particle size
An educational diagram comparing the sizes of airborne particulate matter categories: PM0.1 (ultrafine particles, 0.1 microns), PM2.5 (combustion particles, organic compounds, metals; <2.5 microns), and PM10 (dust, pollen, mold; <10 microns). These are shown relative to a human hair (50–70 microns in diameter) and fine beach sand (90 microns in diameter). -
2022-02-14Characterization of annual average traffic-related air pollution levels (particle number, black carbon, nitrogen dioxide, PM2.5, carbon dioxide) in the greater Seattle area from a year-long mobile monitoring campaign
Researchers conducted a year-long mobile air quality monitoring campaign across the greater Seattle area, measuring traffic-related pollutants including ultrafine particles, black carbon, nitrogen dioxide, fine particulate matter, and carbon dioxide at 309 locations. The study developed predictive models of annual average pollution levels to support health research on how traffic emissions affect Seattle residents, particularly the elderly. The findings showed strong spatial variation in pollution levels linked to traffic and land use patterns across the region. -
2021-12-01Healthy Air, Healthy Schools Study: Phase 1 Report
The Healthy Air, Healthy Schools Study Phase 1 Report, published in December 2021 by the University of Washington for the Washington State Legislature, investigates air quality conditions affecting schools in communities near Seattle-Tacoma International Airport, including SeaTac, Burien, Federal Way, Normandy Park, and Des Moines. The study was conducted in partnership with Federal Way Public Schools and Highline Public Schools, with researchers from UW's Environmental & Occupational Health Sciences and Civil & Environmental Engineering departments. It represents the first phase of a broader effort to understand how local air pollution — potentially influenced by airport and related traffic activity — impacts the health of students in these communities. -
2021-05-01Healthy schools; A school based air quality intervention
A 2021 Washington State legislative funding request of $912,810, sponsored by Representatives Tina Orwall and Jesse Johnson, seeks to deploy HEPA portable air cleaners in 20 schools across SeaTac, Des Moines, Federal Way, Normandy Park, and Burien to reduce students' exposure to outdoor air pollution from traffic and wildfire smoke. The University of Washington's Department of Environmental and Occupational Health Sciences would lead the project, measuring indoor air quality improvements and student performance outcomes. The initiative builds on an ongoing 2021 pilot study monitoring air quality in five schools within the Highline and Federal Way School Districts.
