Abstract: A model-based prioritization exercise that considers two aspects, i.e. the hazard of a certain chemical and its exposure levels, and focuses on aquatic ecosystems has been carried out for the Water Framework Directive (WFD) implementation. The exercise also takes into account hazards due to secondary poisoning, bioaccumulation through the food chain and potential human health effects, e.g. due to fish or drinking water consumption. First a list provided by Member States, Stakeholders and NGOs comprising 2034 compounds was evaluated according to hazard and exposure criteria. Then 78 compounds classified as ¿of high concern¿ where analysed and ranked in terms of PEC/PNEC risk ratio (Predicted Environmental Concentration/Predicted No-Effect Concentration). This exercise would need an expert assessment to analyze the applied methodology and the results obtained. As far as possible, one of the main requirements for the tools employed in the model-based prioritization has been that they are freely accessible to interested parties; however this has not always been possible due to the tight schedule of the process and the fact that some estimation/calculation procedures were not available and needed to be developed at JRC. The proposed approach constitutes the first step in setting the basis for an open modular tool that could be used for the next prioritization exercises.
