The analyses in the report focus on comparisons with the primary standards in effect in 1992 to examine changes in air pollution levels over time, and to summarize current air pollution status. The first three chapters of the report cover trends in the six pollutants with National Ambient Air Quality Standards. Chapter 4 presents the information on air toxics. Chapter 5 includes a detailed listing of selected 1992 air quality summary statistics for every metropolitan statistical area (MSA) in the nation. Chapter 6 presents 1983-92 trends for 23 cities throughout the U.S. Chapter 7 presents summary air pollution statistics from other countries to provide a broader range of air pollution information.

This is the twentieth annual report documenting air pollution trends in the United States. As in previous years, the primary emphasis is on those pollutants for which the U.S. Environmental Protection Agency (EPA) has established National Ambient Air Quality Standards (NAAQS). The analyses in this report focus on comparisons with the primary standards in effect in 1992 to examine changes in air pollution levels over time, and to summarize current air pollution status. The six pollutants with National Ambient Air Quality Standards are: carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter whose aerodynamic size is equal to or less than 10 microns (PM-10), and sulfur dioxide (SO2). Executive summary -- Background -- National and regional trends in NAAQS pollutants -- Air toxics -- Air quality status of metropolitan areas, 1992 -- Selected metropolitan trends -- International air pollution perspective.
