Air quality models which link source emissions to environmental concentrations are important tools for controlling air pollution. One type of air quality model is the chemical element balance (CEB) or source-reconciliation model. This is a method to determine the relative air pollution contribution of each of the major sources of a categorical pollutant from measurements of the composition of the categorical pollutant at one or more receptor sites. The method requires the composition of the categorical pollutant be known in the emissions of each source category. The calculation procedure is a multivariate least squares fit of the composition data with a specified number of source coefficients. This paper reports on a study to apply the weighted least squares source-reconciliation technique to a hydrocarbon data set consisting of 192 samples collected aloft over Tokyo, July 16-17, 1981. Eighteen components were determined for each sample, most of which were collected at altitudes between 350 and 700m. Study methods and results are discussed.
