The modeling of the dispersion a pollutants in the atmosphere is a tool that allows predictions to urban and regional scale air quality in this case for total suspended solids (TSP) and particulate matter (PM10) emissions from the production area township coke composed sidewalks Samacá Loma Redonda, La Chorrera and Salamanca. The AERMOD software takes a Gaussian dispersion model. The evaluation of contaminants is analyzed with two environmentals models: urban and rural. The concentrations of TSP and PM10 (ug/m3) established by Resolution 610 of 2010 MAVDT were determined in 18 days with two monitoring stations in the hospital municipal and Salamanca town that exceed the permissible limits (100 and 50 g/m³). It analyzed the meteorological and topographical supplemented with inventory of emission sources as input for modeling the process of atmospheric pollutants emitted by coking.
