Facteurs de variation en évaluation des risques pour la santé liés aux sites et sols pollués

Abstract : Quantitative risk assessment is a definite and structured method of analysis. Although, many factors playing a part in the caiculation can affect the results. There are a lot of sources of incertitudes and variabilities in chronic risk assessment for human health. Modelled phenomena are hardly known (doses-responses relationships, bioconcentration in the food chain, biodegradation...), data are incertain (measures of concentrations in media, ingestion of soll...), and more or less variable (physiological features, individual's lifestyle). In this paper, some examples on the caiculation of risk due to polluted soils and acceptable soil pollution levels are given. Many ways of caiculating are possible. We chose three differents ways (a french one, a dutch one and a californian one). Using differents toxicological data, modeis and at a least level parameters can give results varying of several Orders of magnitude. in this incertain and variable environment, the risk assessor has to choose options. These choices need to be described, explained and if possible justified.
