    The Pima County Department of Environmental Quality (PDEQ) is issuing an air quality advisory due to elevated levels of fine particulate matter at the Children’s Memorial Park monitoring site near Oracle and River Road.

    The monitors at PDEQ’s sites in other parts of town do not have elevated readings. This appears to be a localized event.
    Individuals with heart disease and respiratory sensitivities in the area of Oracle Road and River Road may want to reduce their level of exertion to decrease the amount of particulates they breathe into their lungs. Those most at risk may feel better if they avoid outside exercise, stay inside as much as possible, and keep windows and doors closed to help reduce exposure to particulate matter. 

    Particulate matter is made up of tiny specks of soot, dust, and aerosols that are suspended in the air we breathe. Particulate matter can come from either combustion (cars, industry, fires) or dust from disturbed land that becomes airborne with high winds. 

    PDEQ monitors air pollution in our region at 17 air quality monitoring sites. Up-to-the-hour air pollution levels are available in the air monitoring section of the PDEQ website.

    The public can sign up at the DEQ website to receive Air Quality Advisories and other Pima County Department of Environmental Quality notices directly via email.
