State of the Air 2010 - Air Quality Gains and Losses
Cities across the US are showing success in the fight for healthy air. But despite these gains, the American Lung Association’s State of the Air 2010 report concludes that healthy air remains elusive for most US cities.
The 11th annual report finds that 58 percent of Americans – more than 175 million – live in areas with unhealthy levels of air pollution. A decade of cleanup measures, including reductions in coal-fired powered plant emissions and the transition to cleaner diesel fuels and engines have paid off in cutting levels of deadly particle and ozone pollution. But some cities, mostly in California, had air that was more polluted than in the previous report.
