    The Pima County Department of Environmental Quality (PDEQ) is issuing an air quality health watch for tomorrow, Thursday, April 12, due to the potential for high levels of particulate matter throughout eastern Pima County. Winds are forecasted up to 20 miles per hour (mph) with gusts as high as 40 mph. Wind-blown particulates may remain in the air through Friday afternoon.palo verde
     
    Tomorrow, unusually sensitive individuals with heart disease and respiratory sensitivities may want to reduce their level of exertion when outside to decrease the amount of particulates they breathe into their lungs. Small particles can travel into the respiratory system and cause short-term health effects such as eye, nose, throat, and lung irritation, coughing, sneezing, runny nose and shortness of breath. If they are in dust-prone areas, those most at risk may feel better if they avoid outside exercise 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 disturbed land, dirt roads, construction and mining activity and becomes airborne with high winds. Small particulate matter can also come from combustion sources such as cars, industry, and indoor and outdoor fires.
     
    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. Individuals can sign up to receive Air Quality Advisories and other Pima County Department of Environmental Quality notices via email. In addition, individuals can sign up to receive the Arizona Department of Environmental Quality provides 5-Day Air Quality Forecasts for Pima County.
