Abstract
In this paper, we discuss the most important theoretical aspects of polluted soil Risk Assessment Methodologies, whichhave been developed in order to evaluate the risk, for the exposed people, connected with the residual contaminantconcentration in polluted soil, and we make a short presentation of the major different kinds of risk assessmentmethodologies. We also underline the relevant role played, in this kind of analysis, by the pollutant transport models. Wealso describe a new and innovative model, based on the general framework of the so-called Cellular Automata (CA),initially developed in the UE-Esprit Project COLOMBO for the simulation of bioremediation processes. These kinds ofmodels, for their intrinsic ‘‘finite and discrete’’ characteristics, seem to be very well suited for a detailed analysis of theshape of the pollutant sources, the contaminant fates and the evaluation of target in the risk assessment evaluation.In particular, we will describe the future research activities we are going to develop in the area of a strict integrationbetween pollutant fate and transport models and Risk Analysis Methodologies.
