    The Pima County Department of Environmental Quality (PDEQ) has issued a High Pollution Advisory for Particulate Matter (PM10 and PM2.5) for October 12, 2021, triggered by high winds.

    PDEQ air quality monitors that measure particulate matter are in the “unhealthy” range this morning. The strongest winds have passed through the area, however rain is not in the forecast, so these wind-blown particles may stay airborne for a while. 

    PDEQ encourages older adults and those with heart or lung disease to reduce their level of exertion when outside today. Breathing small particles can irritate the respiratory system and worsen chronic heart and lung diseases.

    PDEQ monitors air pollution in our region at 14 air quality monitoring sites. Up-to-the-hour air pollution levels are available online at the PDEQ website www.pima.gov/deq.

    PDEQ’s Clean Air Program works to educate Pima County residents about potential health effects associated with elevated levels of air pollution and to promote actions to reduce air pollution levels.
