Abstract
This research was initiated to perform statistical analyses of the data from the Los Angeles Catalyst Study. The objective is to determine the effects of the introduction of the catalytic converter upon the atmospheric concentration levels of a number of air pollutants. This report gives an analysis of the CO, Pb, SO4, O3, NO and NO2 data covering the period from June 1974 to November 1977. Models are built to evaluate the freeway contribution to CO and Pb as a function of traffic, windspeed and wind direction. These models are used to assess both the time trend in the pollutant measurements and the pollution concentrations at points near the freeway. Frequency distributions for ambient air quality data near freeways are discussed.

Contents Notes
This research was initiated to perform statistical analyses of the data from the Los Angeles Catalyst Study. The objective is to determine the effects of the introduction of the catalytic converter upon the atmospheric concentration levels of a number of air pollutants. This report gives an analysis of the CO, Pb, SOb4s, Ob3s, NO and NOb2s data covering the period from June 1974 to November 1977. Models are built to evaluate the freeway contribution to CO and Pb as a function of traffic, windspeed and wind direction. These models are used to assess both the time trend in the pollutant measurements and the pollution concentrations at points near the freeway. Furthermore frequency distributions for ambient air quality data near freeways are discussed.
