POLLUTION LOCATOR|Smog and Particulates

The poor air quality that many Americans know as smog and soot is caused by six ubiquitous pollutants labeled criteria air pollutants by government regulators. Over 170 million people currently live in counties where federal air quality standards are not met, facing increased risks of heart and lung disease and premature mortality. Most of the 20 million people suffering from asthma also live in areas with poor air quality: ozone, particulates and sulfur dioxide are all known to worsen the health of asthmatics and trigger asthma attacks. Scorecard identifies the communities with the worst air quality and spotlights the top polluters.

    NOTE:NOTE: Scorecard's data about criteria air pollutants are derived from U.S. EPA's Air Quality System and National Emissions Trend database. Exposure monitoring data are available for 2003, while emissions data are currently only available for 1999. Many U.S. counties do not monitor air pollution, so it is not possible to describe pollutant exposures or characterize potential health risks in these areas.
