The Pima County Department of Environmental Quality (PDEQ) Clean Air Program has issued issuing an Air Pollution Advisory for today, May 26, due to the potential for elevated levels of ground-level ozone air pollution in the Tucson area. People who are sensitive to air pollution may experience shortness of breath, coughing, throat irritation, wheezing, and breathing discomfort.
If sensitive to ozone, individuals may want to limit outside exertion in the afternoon when elevated levels of ozone pollution are more likely to occur. Intense outdoor physical activity causes faster and deeper breathing, which allows ozone to penetrate into parts of the lungs more likely to be injured.
Driving less, avoiding idling your car too much, and fueling your car after 6 p.m. are some of the key ways to limit ground-level ozone. For a complete list of tips and warnings, visit the links above.
