In this article we make a comparative analysis of the performance of the AERMOD and SYMOS’97 dispersion models for simulating the dispersion of odorous compounds in the atmosphere. Although there are a large amount of air dispersion models in literature, there are few data bases that allow the assessment of results obtained by the dispersion simulation of odorous compounds.

The present work is a joint venture project conducted by the Uruguayan Technological Laboratory (LATU), the National Directorate of the Environment (DINAMA) and the Río Negro’s local government. It consists on the application of different methodologies to address the problem generated by the presence of unpleasant odours in Fray Bentos, Uruguay.
