The programme aims to stimulate the development of food-web models for risk assessment of pollution in the terrestrial environment. It could provide a "trait-d’union" between monitoring and validation-oriented ecotoxicological programmes currently running in European countries. A further generalisation of the data derived by these studies to other temporal and spatial scales by application of system modelling is expected. There will be a significant spin-off to fundamental studies in community ecology. More
