Our Nation's Air Pollution Report Card

Fewer Americans have had to breathe unhealthy levels of smog or microscopic soot in recent years, but air pollution remained a threat in counties where more than half the nation lives, the American Lung Association said in an annual report Thursday.

Using data from the U.S. Environmental Protection Agency, the group found that the number of counties in which unhealthy air was recorded fell significantly for the first time in six years, to 390 from 441 in last year's report. The new report covered 2001 to 2003, while the previous one analyzed pollution levels from 2000 to 2002.
