The Pima County Department of Environmental Quality (PDEQ) is issuing an air quality advisory due to elevated levels of ground-level ozone air pollution in the Tucson metropolitan area. Ozone levels are also expected to be elevated tomorrow.
Individuals who are especially 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.
