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. -
ultra-fine-particles
Infographic comparing sizes of airborne particulate matter relative to a human hair (50 micrometres in diameter): ultrafine particles (<100 nanometers), fine particles (<2.5 micrometres), and coarse fine particles (<10 micrometres). The diagram uses scaled spheres to visually illustrate how these pollution particles relate in size to a strand of human hair. -
Washington State Department of Ecology – Air Quality Index Map, Seattle/Sea-Tac Region
Screenshot of Washington's Air Monitoring Network interactive map (Air Quality Program, WDOE, version 2.73.4.19) showing PM2.5 Air Quality Index readings across the greater Seattle–Sea-Tac–Puget Sound area. All visible monitoring stations display green indicators (Good, AQI 0–50). -
2022-05-26Air Quality Monitoring (AQM) Presentation: Sea-Tac Airport Flight Tracks and Airfield Overview
Presentation by Leonard John Mark Smith (Smith AQM) showing aerial maps and flight track data for Sea-Tac Airport. Includes Port Of Seattle lease boundary and zone match line boundary map at 1-inch equals 1,000 feet scale, an aerial overview of the airfield with labeled areas including Transportation Security Administration (TSA), Weatherhaven, and Mount Rainier International -
2022-05-26Air Quality Monitoring (AQM) Presentation: Sea-Tac Airport Flight Tracks and Airfield Overview
This document contains airfield mapping and flight-track data related to Seattle-Tacoma International Airport (Sea-Tac), showing Port of Seattle lease boundaries, zone match lines, and recorded aircraft flight paths in the surrounding region. It includes a radar playback capture from August 14, 2019, depicting a FedEx 397 missed approach and an Alaska 807 departure with a non-standard turn at approximately 2,130 feet MSL. The materials appear to be part of an airport noise or operations review archive documenting aircraft movement patterns around Sea-Tac. -
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. -
2021-12-01MATES V draft report, chapter 5: Ultrafine particles and black carbon measurements
This report chapter examines measurements of ultrafine particles (UFPs) — very tiny airborne particles smaller than 0.1 micrometers — and their potential health effects, including risks to neurological, respiratory, and cardiovascular health. UFPs make up roughly 90% of all airborne particles and are primarily produced by fuel combustion sources such as diesel engines, gasoline engines, and jet engines. People living near heavily trafficked roads, airports, refineries, and railyards may face elevated exposure to these particles. -

2021-01-18Ambient air quality monitoring platform
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. -
The Sea-Tac Airport Annual Air Quality Monitoring Proposal (STAAQM)
This post describes a proposal we have put forward to Washington State legislators Senator Karen Keiser (33rd) and Representative Jesse Johnson (30th). In one sentence, we want an annual report of all key aviation-related emissions for every neighborhood affected by the operations from Sea-Tac Airport. We refer to this proposal as Sea-Tac Airport Annual Air
