This presentation from the 2024 International Society of Exposure Science annual meeting describes a mobile air quality monitoring study conducted in Seattle, Washington, aimed at measuring exposure to pollutants from specific pollution sources. Researchers from the University of Washington used a multi-pollutant mobile monitoring campaign to assess how residents are exposed to various types of air pollution across different locations in the city. The study covers methods, results, and conclusions related to source-specific air pollution exposure assessment.

A University of Washington research team presented findings to a community advisory group showing that HEPA air purifiers in classrooms near Sea-Tac Airport reduced ultrafine particle (UFP) levels from 50% down to just 10% of outdoor concentrations. The meeting, held August 8, 2022, also covered a small pilot health study suggesting short-term cardiovascular and respiratory differences in people exposed to aircraft UFPs while walking under flight paths. Participants from government agencies, community organizations, and public health departments discussed next steps including expanded outdoor monitoring, wildfire response planning, and potential new funding through the HEAL Act.

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.

This research presentation describes a mobile air monitoring study conducted in Seattle to measure ultrafine particulate matter and black carbon pollution levels for elderly residents participating in the Adult Changes in Thought (ACT) study, which investigates aging and dementia. Researchers used a vehicle-mounted monitoring system to collect repeated short-term air quality samples across the Seattle area, aiming to estimate long-term pollution exposure for cohort participants aged 65 and older. The study is funded by the National Institute of Environmental Health Sciences and the National Institute on Aging.

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.

This December 2020 report, prepared by Public Health Seattle & King County in response to Washington State House Bill 1109, examines how noise and air pollution from airport operations affect the health of communities near Sea-Tac Airport compared to the rest of King County. It reviews evidence on pollutants such as ultrafine particulates, their links to conditions like asthma, heart disease, and reduced life expectancy, and includes findings from a University of Washington study on air quality. The report concludes with recommendations for addressing these public health impacts.
