Résumé
The present work deals with the analysis of mercury vapour dispersion around an old mine area, presently used as a storage facility. To perform such analysis, we have elaborated two distribution models, one on the basis of real data of mercury vapour inmission in the area, and the second on the basis of a gaussian model that considers the facility as the unique source for the mercury vapours. Results indicate that emission from the facility is very low, producing in the surrounding area an insignificant increase in mercury inmission, that can be evaluated in 1-3 ng Hg · m-3. As a matter of fact, in the model obtained with real data the influence of this emission is negligible, and it seems to be controlled by soil contamination by the old mine dumps and related activities.
