The Arizona Department of Environmental Quality in Phoenix has extended a Ozone High Pollution Advisory for the Greater Phoenix Area through Thursday, Aug. 15.

This means that forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates.

Ozone is an air contaminant which can cause breathing difficulties for children as well as persons with respiratory problems. A decrease in physical activity is recommended.

If it is a regularly scheduled work day, you are urged to car pool, telecommute or use mass transit.

The use of gasoline-powered equipment should be reduced or done late in the day.
