    The Pima County Department of Environmental Quality (PDEQ) is canceling the air quality advisory that was issued earlier today. Levels of particulate matter have dropped considerably since this morning.

    However, unusually sensitive individuals may still wish to reduce their level of exertion when outside as long as elevated wind speeds continue.
     
    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 dust from disturbed land that becomes airborne with high winds and also from combustion sources such as cars, industry, and indoor and outside fires.
    alert
    PDEQ monitors air pollution in our region at 16 air quality monitoring sites in eastern Pima County. Up-to-the-hour air pollution levels are available in the air monitoring section of the PDEQ website at www.pima.gov/deq. Individuals can sign up to receive Air Quality Advisories and other Pima County Department of Environmental Quality notices directly via email at https://webcms.pima.gov/cms/one.aspx?portalId=169&pageId=68600.
