The American Lung Association's State of the Air 2012 report, released in April, ranked the top U.S. cities with the least year-round particle pollution.
Air quality in America's most polluted cities was reported to be at the cleanest since the American Lung Association began its report 13 years ago.
The top ten cities with the cleanest air (year-round particle pollution) are:
#1. Santa Fe-Espanola, N.M.
#2. Cheyenne, Wyo.
#3. Prescott, Ariz.
#4. Tucson, Ariz.
#5. Albuquerque, N.M.
#6 Redding, Calif.
#7. Colorado Springs, Colo.
#8 Flagstaff, Ariz.
#9. Anchorage, Alaska
#9. Boise City-Nampa, Ind.
"State of the Air shows that we're making real and steady progress in cutting dangerous pollution from the air we breathe," said Charles D. Connor, American Lung Association President and CEO in a press release.
While great strides have been made in reducing air pollution, Connor stresses that there is much more work to be done. "But despite these improvements, America's air quality standards are woefully outdated, and unhealthy levels of air pollution still exist across the nation, putting the health of millions of American's at stake."
The report found that nearly 4 out of 10 U.S. residents live in counties that received an F grade for air quality because of unhealthy levels of ozone pollution.
"We still need to fulfill the promise of clean, healthy air for everyone, and that can only become a reality through the full implementation of the Clean Air Act," said Connor.
