The American Lung Association released their "State of the Air 2010" report on Wednesday. The report analyzes ozone and particle pollution levels and then ranks the cities/neighborhoods in three categories:
  • Ozone
  • Short-term particle spikes
  • Long-term particle averages
California once again performed poorly with three cities - Los Angeles, Fresno and Bakersfield - all ranking in the top 10 in the three categories.
