Breathe easy in Honolulu, Santa Fe
HONOLULU and Santa Fe, New Mexico, are the US cities with the best air quality, while Los Angeles and several others had the foulest, according to an American Lung Association report.
While the nation's most smoggy cities all improved their air quality over the last year, half the nation's residents still live with unhealthy levels of air pollution, said the report, released on Wednesday.
The "State of the Air 2011" report concluded that the US Clean Air Act, the federal law aimed at limiting pollution in US Skies, is working.
"The progress the nation has made in cleaning up coal-fired power plants, diesel emissions and other pollution sources has drastically cut dangerous pollution," said Lung Association President Charles Connor in a statement.
The biggest improvement has been controlling ozone, commonly known as smog, with all 25 cities most polluted by ozone having cleaner air than they did last year.
Still, 154.5 million people, just over half the US population, live in areas where the air is filled with dangerous levels of smog and particle pollution, known as soot.
The worst three cities for ozone pollution were Los Angeles, Bakersfield and Visalia, all in California. Bakersfield and fellow California city Fresno, along with Pittsburgh, Pennsylvania, had the most short-term particle pollution. Bakersfield, Los Angeles and Phoenix had the worst year-round particle pollution.
