April 28-May 2, 2014, is Air Quality Awareness Week. The quality of the air we breathe affects us all. Those of us who have lived in Denver for decades remember the Brown Cloud that often used to hang over the city. Although air quality and pollution prevention has improved over the years through improvements in technology, such as fuel-efficient vehicles, it is still an important issue faced by Coloradans — and not just those in urban areas, either. The Colorado Department of Public Health and Environment’s Air Pollution Control Division monitors and regulates air quality in our state. You can find a number of publications from the Division in our library. Search keywords “air pollution” or “air quality” in our catalog to find titles, many of which are available online. You can also visit the Division’s website for additional resources, including information on auto emissions, greenhouse gases, open burning and prescribed fires, asbestos, and more.
