Build the idea
The AQI communicates pollution risk
The Air Quality Index converts concentrations of major pollutants into categories and health guidance. Ground-level ozone and fine particles are common concerns. Sensitive groups may need precautions at lower levels than the general population.
Different indices measure different hazards
The UV Index communicates potential harm from ultraviolet radiation. Heat Index estimates how hot conditions feel when humidity limits evaporative cooling. These are not interchangeable with air temperature or the AQI.
Monitoring supports stewardship
Sensors and forecasts help communities issue guidance. Individual actions can reduce exposure, while community choices can reduce emissions and improve resilience. Wildfire smoke can sharply raise particle pollution even far from the fire.
Stop and explain
Check your thinking
1. Why might asthma patients receive guidance before others?
Possible response: They can be more sensitive to ozone or particle pollution.
2. Why can high humidity raise Heat Index?
Possible response: It slows sweat evaporation, reducing the body's cooling.
