According to the CBS Evening News (4/28, story 8, 0:20, Couric), a report released by the American Lung Association focuses on "American airspace and air quality." The group "credited cleaner diesel engines and controls on coal-fired power plants for decreasing pollution, such as soot and dust," the AP (4/29, Manning) reports. Still, millions of "people live in areas with chronic levels of pollution, so that even when levels are relatively low, people can be exposed to particles that will increase the risk of asthma, lung damage, and premature death."
In fact, "high air pollution levels threaten the health of 175 million people, about 58% of the population," the Los Angeles Times(4/28, Roosevelt) reported. "But in California, the proportion is far higher: 91% of state residents, more than 33 million people, live in counties with poor air quality, especially in Southern California and the Central Valley." What's more, the "state's cities and counties, with their ports, refineries, power plants and crowded freeways, rank near the top for particle pollution." Some of the increase is partly attributable to the "thousands of California wildfires in 2008," the Fresno Bee (4/28, Grossi) reported.
There were, however, "considerable...improvements" in air quality, HealthDay (4/28, Mozes) reported. "Atlanta, Cincinnati, Cleveland, New York City, Pittsburgh, St. Louis, Washington, DC and Baltimore all experienced a drop in both smog and soot levels," according to the 11th annual release. "In terms of year-round particle pollution exposure, Cheyenne, WY, came out on top." The "metropolitan Phoenix/Mesa/Scottsdale perimeter of Arizona topped the list of 'most polluted' urban jurisdiction in terms of year-round particle pollutant exposure," while "Los Angeles topped the list for worst ozone pollution."
The Florida Times-Union (4/28, Patterson), the Pittsburgh Post-Gazette (4/28, Hopey), the Las Vegas Sun (4/28, Hansen), the New Jersey Star-Ledger (4/28, Murray), and WebMD (4/28, Hendrick) also covered the report.
