Abstract |
The National Air Surveillance Networks provide information on air quality for many urban and nonurban locations within the United States. This report summarizes the network data for two nonmetallic inorganic ions (nitrate and sulfate) determined from high volume samples collected during 1977 and 1978. Concentration values are presented in the form of cumulative frequency distributions. Arithmetic and geometric sample statistics are also reported, as are measures of the precision and bias associated with the analytical methods employed. |
