The University of Washington's Department of Environmental and Occupational Health Sciences is developing two mobile air quality monitoring platforms to identify pollutant mixtures in Washington communities affected by sources such as non-roadway transportation, industrial emissions, and burn events. The $925,000 project will equip hybrid SUV vehicles with instruments measuring ultrafine particles, black carbon, nitrogen dioxide, carbon monoxide, and other pollutants, enabling flexible and simultaneous monitoring at multiple locations. The project will also produce standardized sampling protocols and community engagement strategies to support long-term air quality trend analysis.

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.

Researchers from the University of Washington studied ultrafine particles (UFPs) — tiny airborne pollutants less than 100 nanometers in diameter — near Seattle-Tacoma International Airport. Their findings highlight that jet aircraft engines produce exceptionally small particles (under 30 nanometers), while diesel vehicles also contribute elevated UFP levels within about 200 meters of major roads. Although UFPs are currently unregulated, a growing body of scientific evidence suggests they pose significant health risks to nearby communities.
