Kids Air Quality Index (AQI)
Air Quality Index For Kids! Do you ever wonder how much pollution is in the air? The AQI is the measurement that we use to keep track of the air quality in the San Joaquin Valley. As you can see from the chart below, from 0-50 is considered good air quality, 51-100 is considered moderate air quality, and 101 and above is unhealthy air quality. When air quality is unhealthy, slow down when you play and limit your time outside, especially if you have asthma.

To find out what today’s air quality is in your area, click on http://www.valleyair.org/aqinfo/forecast.htm or call 1-800-SMOG-INFO.
