Please see www.epa.gov/airtrends for the latest information on Air Quality Trends.
These Web pages present a summary of the complete 1996 National Air Quality and Emissions Trends Report, which is a more technically detailed report. The Trends Brochure and the Trends Report are two separate publications, but the statistical information contained in the brochure was obtained from the Trends Report. A Web version of the complete Trends Report is now available. A limited number of copies will also be available from the Air Quality Trends Analysis Group in Research Triangle Park, NC.
