KEY: R = Revised.
NOTES: The Air Quality Index (AQI) integrates information
on 5 major pollutants (particulate matter less than 10 microns in diameter,
sulfur dioxide, carbon monoxide, ozone, and nitrogen dioxide) across an entire
monitoring network into a single number that represents the worst daily air
quality experienced in an urban area. An AQI greater than 100 indicates that
at least 1 criteria pollutant exceeded air quality standards on a given day;
therefore, air quality would be in the unhealthful range on that day. In 1999,
4,184 monitoring sites reported air quality data. Air quality monitoring sites
are selected as "trend sites" if they have complete data for at least
8 of the 10 years between 1990 and 1999.
SOURCE: U.S. Environmental Protection Agency, Office of
Air Quality Planning and Standards, National Air Quality and Emissions Trends
Report, 1999 (Research Triangle Park, NC: 2001), table A-17.
