Welcome to the Pima County Department of Environmental Quality Air Info
Now web site, dedicated to providing current air quality
information for the metropolitan Tucson area. This website was developed with a grant from U.S. EPA and with assistance from
The University of Arizona, The American Lung Association and Pima Association of Governments. Here you will find

information on air pollutants, their health
effects, activities to help
understand air pollution along with historic and current monitoring
data.

This page provides links to these areas and also displays a quick
snapshot of current air quality conditions. The updating photos

building. In the table below are air quality index
(AQI) values,
