1. Los Angeles is the worst, and this has been proven.
2. The American Lung Association has your air quality answer! http://lungaction.org/reports/sota06_cities.html Also check out the EPA website for information on a variety of things like superfund sites, water quality, etc. http://www.epa.gov/ The Ohio EPA (State agency) also has some info on their website at http://www.epa.state.oh.us/
