People in the U.S. are breathing cleaner air than a year ago, but there’s still plenty of room for improvement.
So says the American Lung Association’s (ALA) “State of the Air 2006.” The annual report focuses on particle pollution (soot) in the air, as well as ozone levels (smog).
Last year’s winners and losers for year-round soot pollution didn’t change. Cheyenne, Wyo. still has the least year-round soot pollution, while the Los Angeles area has the most year-round soot pollution, according to the ALA.
Sooty air showed a “general decline” since the ALA’s 2005 report, largely due to pollution-cutting programs at coal-fired power plants.
But soot and smog remain “persistent threats against large parts of the United States,” according to the ALA.
Filthy air isn’t healthy for anyone, but it can be particularly hazardous for senior citizens, children, and people with asthma, chronic obstructive pulmonary disease (COPD), heart disease, or diabetes, notes the ALA.
More than half of the U.S. population lives in counties that have unhealthful levels of smog or soot, the report also states. However, some towns had cleaner air than others.

Cheyenne, Wyo., leads the ALA’s latest list of the top 25 U.S. towns with the least long-term particle pollution (soot). Here is that list. Metropolitan areas that tied received the same number.
