Resumen

In absence of information about the system to be simulated, it is important to know the uncertainties associated with the assumptions made. The present work is a comparative study of the effect of the height and location of stacks on the spatial distribution of pollutants in the air and the pollutant concentration on the surface using the Lagrangian particle dispersion model (LADISMO). The study was applied to the dispersion of total suspended particles (TSP) from 27 stacks located in an industrial center in Venezuela. The criterion for comparing Lagrangian particle paths has proved to be stricter than the criterion for comparing TSP-24h concentrations. Furthermore, the effect of the height of emission sources seems to be not important if just a maximum of 25% of the stack heights are modified and the effect of the location of emission sources on the trajectory of pollutants seems to be not relevant.
