This report presents national and regional trends in air quality through 1975 for total suspended particulate, sulfur dioxide, carbon monoxide, nitrogen dioxide and oxidants. The change in the number of people exposed to air quality levels above the National Ambient Air Quality Standards is emphasized. Changes in air quality levels are discussed for two selected areas: the New York-New Jersey-Connecticut Air Quality Control Region, accounting for 17 million people, and the Los Angeles Basin, accounting for 8 million people. The trend analyses in this report are based on the data collected through the extensive monitoring activities conducted by Federal, State and local air pollution control agencies. Nationwide emissions for the period 1970-1975 are also presented.
