A mathematical model was used to predict the characteristics of fine organic aerosol that would be present in the Los Angeles atmosphere if direct organic aerosol source emissions were transported without chemical reaction. The model was successful at tracking both the seasonal variations observed in ambient samples of organic aerosol, and the distribution of the urban organic material present as a function of gas chromatographic elution time. Using the model, the major sources of urban organic aerosol were identified for this urban area. Differences between ambient measurements and model predictions were used to assess the degree of secondary organic aerosol formation. 5 refs., 1 tab.
