Abstract The present work proposes a methodology to study the influence on air pollution monitoring stations by vehicular emissions using a Geographic Information System (GIs). As a preliminary study, only one air pollution monitoring station has been chosen as an example. We studied four elements, Zn, Ba, Cu and Pb. The Gaussian plume model was adopted to determine the contribution fiom vehicles to elemental concentrations measured at the monitoring station. When modeling the dispersion, the line pollution sources representing emissions fiom vehicles traversing the streets were treated as if they were on top of the canyons. This was made possible since the time peri
