National air quality and emissions trends report, 1976

Technical Report · Thu Dec 01 04:00:00 EST 1977

OSTI ID:7092483

This report presents national and regional trends in air quality through 1976 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 for four major metropolitan areas: the New York-New Jersey-Connecticut Air Quality Control Region; the Los Angeles Basin; the City of Chicago and Metropolitan Denver. All areas show long-term improvement in reducing adverse pollution levels. A major feature of this report is the presentation of multi-color air quality maps for total suspended particulate, sulfur dioxide and photochemical oxidants. The 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 to 1976 are also presented.
