    The Pima County Department of Environmental Quality has issued an air quality advisory due to elevated levels of wind-generated particulate matter.  none

    Individuals with heart disease and respiratory sensitivities may want to reduce their level of exertion to decrease the amount of particulates they breathe into their lungs, especially if they are near dust-prone locations. Those most at risk may feel better if they avoid outside exercise today, stay inside as much as possible, and keep windows and doors closed to help reduce exposure to particulate matter.

    The National Weather Service is predicting winds as high as 40 miles per hour in the Tucson area this afternoon.

    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.

    The department monitors air pollution in our region at 17 air quality monitoring sites. Up-to-the-hour air pollution levels are available online at the PDEQ website www.airinfonow.org or by calling the department's hotline at (520) 882-4AIR.
