Air Quality     Central District

To CD Home > To CD Air >



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


Ozone Reports and Data


Steps You Can Take to Help Keep Our Air Clean

  • Conserve energy-at home, at work, everywhere.

  • Conserve electricity and set your air conditioner at a higher temperature.

  • Follow gasoline refueling instructions for efficient vapor recovery. Be careful not to spill fuel and always tighten your gas cap securely.

  • Choose a cleaner commute-share a ride to work or use public transportation. Bicycle or walk to errands when possible.

  • Keep car, boat, and other engines tuned up according to manufacturers' specification.

  • Defer use of gasoline-powered lawn and garden equipment until the cool of the day.

  • Be sure your car tires are properly inflated.

  • Refuel cars and trucks after dusk.

  • Carpool, use public transportation, bike, or walk whenever possible.

  • Combine errands and reduce trips.

  • Use environmentally safe paints and cleaning products whenever possible.

  • Limit engine idling.

  • Some products that you use at your home or office are made with smog-forming chemicals that can evaporate into the air when you use them. Follow manufacturers' recommendations for use and properly seal cleaners, paints, and other chemicals to prevent evaporation into the air.

  • Use household, workshop, and garden chemicals in ways that keep evaporation to a minimum, or try to delay using them when poor air quality is forecast.
