How does the EPA measure air pollution?
The most basic is the Ambient Air Monitoring Program, which collects national air quality data on criteria pollutants: Carbon Monoxide (CO), Oxides of Nitrogen (NO2 and NO3), Ozone (O3), Lead (Pb), Particulate Matter (PM) – both particulates with aerodynamic diameters below 10 micrometers (PM-10) and particulates with …

How is pollution measured?

The Environmental Protection Agency manages the national ambient air quality monitoring network. We also measure the levels of a number of atmospheric pollutants. The pollutants of most concern are those whose main source is traffic such as Particulate Matter and Nitrogen Dioxide.
