Air pollution is an important risk factor for various diseases, such as COPD (a common lung disease), stroke, ... Air quality indexes (AQIs) ...
Passive or "diffusive" air sampling depends on meteorological conditions such as wind to diffuse air pollutants to a sorbent medium. Passive samplers, such as diffusion tubes, have the advantage of typically being small, quiet, and easy to deploy, and they are particularly useful in air quality studies that determine key areas for future continuous monitoring.
IQAir used as its primary indicator of each country or territory’s air quality the average concentration of PM2.5, or particulate matter with a diameter of 2.5 micrometers or smaller, measured ...
The U.S. has a measurement system for air quality called the air quality index (AQI). The AQI has six color-coded categories with a value system that runs from zero to 500.
