Air Quality Central District
In the Earth's lower atmosphere, near ground level, ozone is a harmful air pollutant also known as "smog." Ground-level ozone is formed when nitrogen oxides and volatile organic compounds (gases emitted by cars, power plants, industrial plants, gasoline dispensing facilities, painting operations, and natural sources) react chemically in the presence of sunlight. Ground-level ozone builds up during the day, especially during warm weather, and drops off at night.
The amount of ground level ozone in the air is measured in parts per billon or ppb. Monitors around the state measure ozone. EPA established the Air Quality Index (AQI) for reporting daily air quality. Ozone is one of the AQI measurements.
Areas of Florida may experience a few days each year when ozone levels are high enough to affect the health of sensitive persons. On such days, the AQI may reach the "yellow" or "orange" range and some people may experience coughing, throat irritation, and breathing discomfort. Look for the Air Quality Index report in your local media or view the AQI report online on our Air Quality Monitoring page.Many everyday activities produce emissions that contribute to ozone formation. You can help reduce these emissions. How you can help keep our air clean
