The Pima County Department of Environmental Quality (PDEQ) has announced that the Tucson metropolitan area is to brace for an Ozone Action Day today. Due to the expected rise in ground-level ozone, residents with particular sensitivities to air pollution may notice adverse health effects. PDEQ warns that symptoms such as shortness of breath, coughing, throat irritation, wheezing, and discomfort when breathing may be more pronounced on this day, particularly during the hours from noon to sunset. PDEQ urges those with respiratory issues, active adults and children, and individuals with specific sensitivities to ozone to limit outdoor activities and exertion during peak times, as reported by Pima County.
Several common emissions contribute to the formation of ground-level ozone. These include motor vehicle exhaust, industrial emissions, gasoline vapors, and chemical solvents. When mixed with intense sunlight and heat, oxides of nitrogen (NOx) and volatile organic compounds (VOC) from these sources can combine to form harmful ozone, as per Pima County. To combat these risks and particularly help those most vulnerable, PDEQ recommends various actions to reduce ground-level ozone production. These measures range from consolidating driving errands to using low-VOC paints and products.
Individuals experiencing any of the symptoms mentioned should seek medical help as needed. The PDEQ highlights this advisory as part of its ongoing Clean Air Program dedicated to educating residents about air pollution and promoting actions that can minimally impact air quality, as detailed by Pima County. With the risk of heightened pollution, PDEQ’s advice goes beyond health, encompassing suggestions such as avoiding the use of gas-powered equipment and conserving electricity to address broader environmental concerns.
