The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix metro area Monday, warning that forecast conditions are expected to push 8-hour ozone concentrations to levels that pose a health risk. The advisory runs through 9 p.m. Tuesday, July 7.
The National Weather Service relayed the alert at 8:42 a.m. Monday, covering Maricopa. ADEQ says ozone is an air contaminant that can cause breathing difficulties for children, older adults, and people with respiratory problems, and that adverse health effects increase as air quality deteriorates. A decrease in physical activity is recommended for those groups.
Residents are urged to carpool, telecommute, or use mass transit. Use of gasoline-powered equipment should be reduced or shifted to late in the day, when ozone-forming conditions are less intense.
Full advisory details are available at azdeq.gov/forecast/phoenix or by calling ADEQ at 602-771-2300. The advisory expires at 9 p.m. July 7.
