May 1, 2007 -- The American Lung Association today released its 2007
"State of the Air" report, which includes good news and bad news about
America's air quality.
The good news: Smog levels across much of the country are lower than they
were from 2003 to 2005, especially in the eastern U.S.
The bad news: Soot levels are rising in the eastern half of the nation. Soot
levels are also high in many parts of the western U.S., but soot levels have
dropped there since 2003-2005.
The report also includes the American Lung Association's annual list of the
metropolitan areas with the most and least year-round soot.
The top spots are unchanged from last year. Cheyenne, Wyo., still has the
least sooty air, and Los Angeles continues to lead the country in sooty
air.
