The Pima County Department of Environmental Quality (PDEQ) has
issued an Ozone Action Day for the Tucson Metro area until 8 PM MST
this evening.

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 pollutant which can cause breathing difficulties for
children, older adults, as well as persons with respiratory
problems. A decrease in physical activity is recommended.

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.

For details on this Action Day, visit the PDEQ website at
www.pima.gov/deq or call 520-724-6885.
