Abstract: A bioaccumulation model to predict, based on the concentration of contaminants in the water column, the concentration in mussels (Mytillus galloprovinciales) has been implemented and calibrated using experimental data from Thau lagoon (France). The model uses input data from a 3D biogeochemical model that provides biomasses in the different compartments, i.e. phytoplankton, zooplankton and bacteria; and from a 3D fate model that provides the concentrations in the water column as well as in the sediments. The bioaccumulation model is based on the Dynamic Energy Budget approach (DEB). The model predicts correctly the concentrations of several POPs families: PCDD/Fs and PCBs. This is the first step for developing a general screening tool able to predict the bioaccumulation of new chemicals in mussels based on its physico-chemical properties that will contribute to the B(bioaccumulative) and vB assessment. In addition, the model could be use by MS to convert measured concentrations in mussels to water concentrations for WFD (Water Framework Directive) compliance checking.
