The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix metro area Monday, effective 9:04 a.m. and running through 9 p.m., according to a National Weather Service alert.
Forecast weather conditions combined with existing ozone levels are expected to result in local maximum 8-hour ozone concentrations that pose a health risk, the advisory states. Adverse health effects increase as air quality deteriorates.
Ozone is an air contaminant that can cause breathing difficulties for children, older adults, and persons with respiratory problems. A decrease in physical activity is recommended for those groups.
Residents are urged to carpool, telecommute, or use mass transit. The use of gasoline-powered equipment should be reduced or deferred until late in the day.
Who is most at risk?
Children, older adults, and people with existing respiratory conditions face the greatest health risk during an Ozone High Pollution Advisory. The ADEQ advises those groups to decrease physical activity while the advisory is in effect.
