    abstract = {An unsteady state Lagrangian diffusion model with consideration for the removal of sulphur dioxide through chemical transformation in the planetary boundary layer has been developed and evaluated in comparison with 2 existing models. The data used were from episodes of industrial emissions in a sub-urban area monitoring studies in South Africa. The effect of varying transformation rate was investigated using the three different overall rate constants for the advection of SO<SUB>2</SUB> in smoke plume between a source (power station smoke stack) and a receptor point (ground based sampling site) under the influence of the local meteorology. The concentration distribution in the along-wind direction revealed that SO<SUB>2</SUB> oxidation rate as second order with deposition as first order predicted the observed ambient concentration to an accuracy of about 91.9%.}
