smog level
Urban air quality
Smog level refers to the measured concentration of smog—the hazy mixture of pollutants, particularly ground-level ozone and particulate matter—in the air at a given time and place.
Health agencies issue warnings when smog levels rise: The smog level today is unhealthy for sensitive groups.
High smog levels trigger air quality alerts and advisories to limit outdoor activity.
