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). -
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). -
Human Respiratory System Gas Exchange
A labeled educational illustration depicting the human respiratory system (trachea, bronchus, lungs, heart, diaphragm, alveoli, pulmonary arteriole and venule) and a detailed diagram of alveolus gas exchange showing oxygen intake and carbon dioxide expulsion via capillaries and red blood cells.

Effects of Ultrafine Particles
Infographic from Daily News, illustrated by staff artist Warren Huskey, explaining how atmospheric ultrafine particles (diameter less than 0.1 micrometers) enter the human body and cause adverse health effects including possible brain cancer, heart attacks, and liver invasion. It details particle size comparisons (PM10, PM2.5, and ultrafines) relative to human hair thickness of 60 microns. -
Lung Cancer
A detailed medical infographic titled 'Lung Cancer' covering risk factors, types (small cell and non-small cell), stages, early detection methods, and treatments. Includes sections on environmental/external risk factors such as asbestos, beryllium, radon, and Agent Orange, with particular relevance to veterans. -
king county air ventilation
Infographic by Mark Nowlin for The Seattle Times, sourced from the Centers for Disease Control and Prevention, illustrating how various ventilation methods (no ventilation, open window, portable HEPA air filter, HVAC system) reduce airborne particles that may contain coronavirus. Data shows particle reduction percentages at end of a 4-hour visit and 1 hour later for six ventilation scenarios. -
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. -
Compendium of WHO and other UN guidance on health and environment
Welcome to the global repository of interventions for creating healthier environments and improving health The Compendium is a comprehensive collection of available WHO and other United Nations (UN) guidance for improving health by creating healthier environments. It provides an overview and easy access of 500 actions, and a framework for thinking about health and environment -
2022-01-01Compendium of WHO and other UN guidance on health and environment: 2022 update
This 2022 WHO compendium brings together guidance from the World Health Organization and other United Nations agencies on the links between human health and environmental factors. It covers topics such as air quality, water, sanitation, and climate-related health risks, providing policymakers and practitioners with a consolidated reference for evidence-based standards. The document is produced in collaboration with UNDP, UN Environment, and UNICEF.
