This paper presents a comparison between the screening method in accordance with the requirements of the Argentine regulations and the detailed screening procedures recommended by the United States Environmental Protection Agency (US-EPA). Both methodologies are applied to different scenarios of point sources in rural and urban areas. The intercomparison between both screening estimations is evaluated by calculating the quantitative model performance measures included in the Model Validation Kit. The Argentine regulations are restrictive with respect to US-EPA requirements. This restriction is greater when the impact of the emissions from a single point source or from multiple equal sources is evaluated.Fil: Venegas, Laura Esperanza.
