Smog Alerts

Smog, a combination of “smoke” and “fog” is a mixture of air pollutants.  In Georgia the two most important pollutants that threaten human health are ground-level ozone and particle pollution.

Air pollution levels can vary throughout the day. Ozone concentrations increase during the day as temperatures rise and pollutants react with one another. The highest levels occurring between 2-7 p.m. On the other hand, particle pollution can be experienced at any time of the day, and unlike ozone which is driven by heat, high levels of particle pollution can occur year-round.

The Clean Air Campaign issues Smog Alerts on days when concentrations of ozone or particle pollution – or both are expected to reach unhealthy levels.

The Air Quality index (AQI) has five color-coded levels alert the public of the health advisories for each day.

Good 0 – 50 Air quality is good. Enjoy activities.
Moderate 51 – 100 People who are unusually sensitive to air pollution should consider reducing prolonged or heavy exertion.
Unhealthy for Sensitive Groups 101 – 150 People with heart or lung disease (including asthma), older adults and children should cut back or reschedule strenuous activities.
Unhealthy 151 – 200 Everyone, especially people with heart or lung disease (including asthma), older adults and children should cut back or reschedule strenuous activities. Sensitive groups should avoid strenuous activities.
Very Unhealthy 201 – 300 Everyone, especially people with heart or lung disease (including asthma), older adults and children should significantly cut back on physical activities. Sensitive groups should avoid all physical activities.
