Abstract: The modelling system RAMS/CALMET/CALPUFF was used to simulate the atmospheric dispersion and deposition of dioxins emitted from industrial sources over the Province of Lecce (Italy). Comparison between data and predictions shows that the model reasonably simulates the deposition patterns. Dry deposition of PCDD/F extends mainly downwind of the sources following the prevailing wind direction. Wet deposition of PCDD/F is limited to the neighborhood of the emission sources and is associated with the highest PCDD/F deposition values.
