The University of Washington School of Public Health was directed by Washington State to study ultrafine particle air pollution near Sea-Tac Airport, the state's busiest international airport. The study assessed air quality within 10 miles of the airport along flight paths, distinguishing between aircraft and other pollution sources, and comparing affected areas with unaffected ones. Findings were shared with local governments and community members, with a final report due December 1, 2019.

A University of Washington Epidemiology researcher, Anna Harrington, presents findings showing that communities near Seattle-Tacoma International Airport have higher rates of preterm births and are home to a disproportionate share of King County's people of color and low-income residents. The presentation proposes a qualitative research study to explore how airport community stakeholders perceive the public health risks of SeaTac air pollution on pregnant people, and what barriers they face in reducing that exposure. The study aims to understand whether risk perceptions and mitigation strategies differ based on the racial identity and income level of pregnant individuals.

A University of Washington research team held an advisory group meeting in August 2022 to discuss ultrafine particle (UFP) pollution in urban areas near airports. The meeting covered topics including indoor air quality in schools affected by aircraft emissions, short-term health effects of UFPs, and plans for mobile air quality monitoring. The multidisciplinary team includes environmental health scientists, researchers, and public health experts examining how aviation-related pollution impacts surrounding communities.

Researchers from the University of Washington School of Public Health examined how aircraft flight traffic at Seattle-Tacoma International Airport relates to ultrafine particle pollution and noise levels in surrounding communities. The study highlights that neighborhoods such as Beacon Hill and other South King County areas already rank among the most environmentally burdened in Washington State, facing cumulative hazards including both air and noise pollution from aircraft. The findings are intended to inform policy discussions about the health impacts of airport operations on nearby, often disadvantaged, communities.

In October 2020, the City of Burien considered joining Des Moines, Federal Way, Normandy Park, and SeaTac in funding a $62,500 University of Washington study examining how ultrafine particles from aircraft emissions penetrate school buildings near Sea-Tac Airport. The first phase of the study would assess the air filtration efficiency of five schools located north and south of the airport, while a proposed second phase ($250,000) would test interventions to improve indoor air quality and measure their impact on student health and academic performance. Each participating city was asked to contribute $12,500, with the City Manager recommending approval of an Interlocal Agreement to move the project forward.

A University of Washington study found that King County neighborhoods with the highest air pollution levels, concentrated in South King County, also experienced the highest COVID-19 infection rates. These areas are predominantly lower-income communities of color with below-average COVID-19 testing access. Researchers note that environmental health disparities, not air pollution as a direct cause, mirror the patterns of COVID-19 spread, and call for more testing resources and culturally appropriate outreach in affected communities.

Researchers at the University of Washington conducted the MOV-UP study to measure ultrafine particle (UFP) pollution around Seattle-Tacoma International Airport and the neighborhoods affected by its air traffic. The study aimed to determine how much of the UFP exposure in surrounding communities comes specifically from jet aircraft, which emit extremely tiny particles (under 30 nanometers) along flight paths, versus other sources like diesel vehicles on nearby roads. Findings and community feedback were shared with local governments to inform air quality and noise policy decisions.

This presentation by Kim Serry, a University of Washington public health graduate student, reviews research on the community health impacts of airports, covering pollutants, health effects, and which populations are most affected. The session, produced in partnership with Public Health Seattle King County and the UW Center for Health Innovation and Policy Science, also examines local conditions relevant to the Sea-Tac area. The 30-35 minute recorded presentation concludes with an open question-and-answer period.

A 2019 University of Washington study found that communities within 10 miles of Seattle-Tacoma International Airport are exposed to ultrafine particle pollution uniquely linked to aircraft emissions, distinct from roadway traffic pollution. These microscopic particles — 700 times thinner than a human hair — are not currently regulated by federal or state air-quality standards, and prior research has associated them with breast cancer, heart disease, prostate cancer, and lung conditions. The policy brief calls on Washington State legislators to fund a follow-up two-year study to investigate the health impacts on nearby communities, which tend to be poorer and more racially diverse than King County as a whole.
