This work presents an analytical representation for a dispersion model of pollutants that considers the chemical reaction, the model uses the three-dimensional advection-diffusion equation to describe the concentration field in the atmospheric boundary layer and to represent the chemical reaction that the pollutant suffers is included a source term in the equation. To solve the problem we use the modified Adomian Decomposition method associated with the 3D-GILTT method. The model was applied to simulate the dispersion and transportation of the $SO_2$ (sulfur dioxide), a pollutant produced from the burning of mineral coal, emitted by the Presidente Médici thermoelectric plant, located in Candiota / RS. With the analysis of the results it can be observed that the concentrations generated by the model are satisfactory and that the approach used is a new proposal for the description of the concentration field of a substance.
