Pima County, Ariz. - The Pima County Department of Environmental Quality is issuing an air quality advisory today due to the windy conditions and the potential for elevated levels of particulate matter.
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.
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 16 air quality monitoring sites with up-to-the-hour air pollution levels available through our
Air Monitoring Section.
