air quality
Atmospheric purity rating
Air quality is a measure of how clean or polluted the air is in a given place.
Government agencies monitor air quality and issue alerts when pollution levels pose health risks: The air quality index today is unhealthy for sensitive groups.
Poor air quality results from vehicle emissions, industrial output, wildfires, and other sources of particulate matter and gases.
