Abstract

The use of pollutants fate simulation models in the risk analysis Abstract In this paper, I describe the most important theoretical aspects of the polluted soil risk assessment methodologies and the relevant role played, in this kind of analysis, by the pollutant transport modcls. In particular. I describe a new and innovative model. based on the general framework of the so called Cellular Automata (CA), initially developed in the Esprit Prqject named COLOMBO (partially sponsored by EU Commission) for the bioremediation phenoniena simulation 111 arid successfully applied to the detailed analysis of the shape of the pollutant sources and of the contaminant fates in the risk assessment evaluation. In particular, I present the simulation of the contaminant distribution in a complex field situation and I shortly describe the future research activities we are going to develop in the arca of a strict integration between pollutant fate and transport models and Risk Analysis Methodologies. 1 Introducti
