Forty years after the Clean Air Act, more people are breathing easier. "In general, we’ve seen tremendous improvement in air quality," says Jonathan M. Samet, MD, director of the Institute for Global Health at the University of Southern California, in Los Angeles.
Cheyenne, Wyo.
Cheyenne is the clear winner: It has the lowest level of year-round PM 2.5 particulates, tiny lung invaders about 1/30th the width of a human hair. Cheyenne's small size may help; fewer cars travel the roads, and vehicles are a key source of PM 2.5 (and ozone).
Santa Fe, N.M.
Popular for both its art galleries and clean air, it may come as no surprise that a Santa Fe artist recently unveiled a sculpture that measures particulate air pollution.
Bismarck, N.D.
Bismarck has some of the lowest year-round particulate levels of all U.S. cities (it comes in at number 11) and ozone levels below what is considered dangerous.
Great Falls, Mont.
It’s a good thing that the small and relatively remote city of Great Falls enjoys clean air, given how much time its residents probably spend outdoors taking advantage of the area’s natural beauty.
Anchorage, Alaska
Anchorage is another city that is protected by a "relatively sparse population," notes Norman H. Edelman, MD, chief medical officer at the American Lung Association.
Amarillo, Texas
"When we consider where the air is most polluted, we often think about California and Texas," Dr. Samet notes.
Redding, Calif.
While California holds many of the top spots in the lineup of the dirtiest U.S. cities, Redding enjoys its place on a healthier list. The city is north of the pollution-prone San Joaquin Valley in a less densely populated area, where it is somewhat buffered from other large cities.
Duluth, Minn.
Small size, remote location, and cold weather conspire to make Duluth one of only seven cities in the U.S. to make it on the list for both lowest year-round particle pollution and ozone levels.
