<abstract>In this study, the Eulerian scalar transport model and the Lagrangian trajectory tracking method were compared in their ability to predict the concentrations around a human shaped body exposed to gaseous contaminants within the length of an arm's reach. It was seen that the Eulerian method exhibited a more diffusive nature than the Lagrangian method. However, the concentration predictions obtained with the Lagrangian method may converge with the Eulerian prediction if an adequate number of trajetories are tracked</abstract>
