The Arizona Department of Environmental Quality issued an Ozone and PM-10 High Pollution Advisory for the Phoenix Metro Area on August 7, effective at 10:14 a.m. and expiring at 9 p.m. MST. Forecast weather conditions combined with existing ozone levels are expected to produce local maximum 8-hour ozone concentrations that pose a health risk. Strong, gusty winds are also forecast to generate widespread blowing dust that may result in elevated PM-10 concentrations.
Ozone can cause breathing difficulties for children, older adults, and persons with respiratory problems. PM-10 can aggravate heart and lung disease conditions, especially in vulnerable populations. The advisory recommends reducing physical activity, carpooling, telecommuting, using mass transit, and reducing or delaying gasoline-powered equipment use until late in the day.
