Rhodes, R., D. Fair, J. Frazer, S. Long, AND W. Loseke. AIR QUALITY DATA FOR METALS, 1976, FROM THE NATIONAL AIR SURVEILLANCE NETWORKS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/4-79/054 (NTIS PB80147432), 1979.
Description:
Particulate pollutant data gathered during calendar year 1976 by the cooperating stations of the National Air Surveillance Networks (NASN) provide the basis for listing the urban and nonurban concentrations of 11 metallic ions in suspended particulate matter. The data are presented as a composite concentration value for each site for each of the four quarters of the calendar year; a yearly average is reported whenever valid data for all four quarters are obtained. In this report overall national summaries are compared for the years 1970 through 1976.
