This report presents information about the six criteria air pollutants (carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, sulfur dioxide) that have National Ambient Air Quality Standards established by the Clean Air Act. The report allows you to rank your community based on pollutant emissions, exposures and potential health risks, breaks down which pollutants and which sources contribute most to criteria air pollution problems, and provides you with opportunities to take action. See Scorecard's overview of criteria air pollution problems.
Data Source: Scorecard's emissions and exposure information for criteria air pollutants is derived from two U.S. EPA sources: the National Emissions Trend database and and the Aerometric Information Retrieval System database.
NOTE: This report only covers the six pollutants for which EPA has established National Ambient Air Quality Standards. Scorecard offers other reports that profile hazardous air pollutants and chemical releases from manufacturing facilities. Criteria air pollutant emissions data are only available for 1999, while exposure monitoring data are available for 2002. Many U.S. counties do not have criteria air pollutant monitoring stations, so it is not possible to describe pollutant exposures of characterize potential health risks in these areas.
