An extensive data collection was undertaken to study the environmental impact of catalytic converters in Los Angeles, Calif. Described is a joint model relating hourly carbon monoxide concentrations at specific monitoring locations to traffic, wind speed, wind direction, and distance of the measurement site from the freeway median. A model for lead that takes into account the fact that lead emissions increase with traffic speed also is discussed. Using this model, it is shown that an observed lead increase in 1977 at a specific site can be explained by the opening of an additional traffic lane, which resulted in higher traffic speed.
