To provide a novel and economic tool for estimation of consumer exposure to chemicals migrating from food contact plastic materials. The tool should be a physico-chemical migration model that describes mathematically the migration processes from plastics into actual foodstuffs under any actual contact conditions. The model will be applicable for exposure estimations in different ways: (I) As a stand alone tool to estimate exposure related migration within the conventional frame conditions of the EU food regulatory evaluation system (that is the consumer eats per day 1 kg food packed completely with the plastic) thus applying a worst case exposure scenario. (II) In conjunction with statistical data obtained from food consumption and food plastics packaging surveys to estimate realistic or worse-case consumer exposure for any situation of interest which is achievable through the flexibility of calculating the migration rate into any food from any plastic and under any contact conditions. To assess the validity of the developed inter-operable modelling software, for food chemical intakes (a mg/d) (food migrants) and with different databases, against true intakes (b mg/d) based on different databases which have been established, to conduct a comprehensive sensitivity analysis of validated models, and to compare these intakes against those derived using the different international sources (c mg/d). In this context the term ¿validation¿ means ¿potential for use in risk assessment¿ as defined by the following minimal acceptable criteria. Models where a < b or a > c will be rejected and stochastic models where a > b and a < c will be deemed eligible for consideration for use in risk assessment, in consultation with the research project (Monte Carlo - Contract n°QLK1-1999-00155) and the concerted action QLK1-1999-00156. (Validation criteria in the strict statistical sense as opposed to the risk assessment sense will evolve in the course of the project).
