The aim of the investigation was to estimate the contributions of uncontrolled wildfires in the air quality of Barranquilla for PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> and PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2.5</inf> . Dispersion of particulate matter, PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> and PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2.5</inf> emitted form vegetation fires presented fires in the Vía Parque Isla de Salamanca was modeled under different scenarios, spatial location, duration, and extension of the burned area. Emissions from the fixed, mobile and area sources of Barranquilla was estimated and then, the AERMOD® V9.0 software was used for dispersion modeling. Results were compared with data of the monitoring air quality stations. Contribution of fires in the simulated scenarios ranged between 28.9%-204.1% for PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> and 6.3%194.7% for PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2.5</inf> .
