The Arizona Department of Environmental Quality issued a PM-10 High Pollution Advisory for the Phoenix Metro Area on Thursday, Aug. 6, effective through 9 p.m. MST, according to a National Weather Service alert issued at 9:42 a.m.
Lingering dust from Wednesday night has produced high local concentrations of coarse particulate matter, known as PM-10, that the agency says pose a health risk. Adverse health effects increase as air quality deteriorates, the alert states.
PM-10 can aggravate heart and lung disease conditions, with older adults, children, and people with asthma at greatest risk. The advisory recommends a decrease in physical activity for those groups.
Residents are advised to consolidate travel, stabilize loose soils, slow down or avoid travel on dirt roads, reduce or eliminate fireplace use, and avoid using gas-powered lawn equipment for the duration of the advisory.
