Description:
This report is a summary of the data collected at the Los Angeles Catalyst Study (LACS) from June 1974 through December 1977. Previous reports of the LACS data were presented at the symposium held in April 1977, covering the data through 1976. The current report follows the same data presentation format, showing 6-month average trends of the summer seasons (April through September) beginning in 1974. Additional graphs are included in this report giving more detailed comparisons of freeway pollutant contributions with traffic parameters. Also included are method comparisons of high volume and membrane samplers for total mass, SO4(-2), Pb, and ratios of S/SO4 and Pb/Br.
