  • Ranking Areas by Health Risk

    Rank states or counties by health risks from Hazardous Air Pollutants
  • NOTE: These rankings are based on exposure estimates derived from 1990 emissions data. There are important uncertainties associated with using models to predict current air quality. Scorecard risk estimates are based on EPA exposure estimates and provide a perspective on the magnitude and sources of hazardous air pollution problems. They are not definitive evaluations of health risk in a particular locale.
