Filtration rate varies with organism weight, ambient temperature (TEMP) and TPM. The rate of consumption depends upon filtration rate. The rate of ingestion depends on consumption rate and on efficiency of particles capture (SEFF). The fraction of particulate matter that is not ingested is egested by blue mussel as pseudofeces. Absorption rate depends on characteristics of the particulate matter, such as concentration, size and food quality (AEPHY, AEDET) and controls the increment of state variables x(1) and x(2). Bioaccumulation model The formulation of the blue mussel bioaccumulation model follows the developments of Thomann and Connolly (1984) and Loizeau and Ménesguen (1994). The bioaccumulation model is based on a single-compartment chemical mass balance for the organism, which controls the time evolution of state variable x(3). Introduction The purpose of this poster is to present a generic framework for modelling bioaccumulation of PCBs in blue mussel from the Bay of Seine. This bay and its estuary are heavily polluted by various contaminants from terrestrial origin. The National Monitoring Network (RNO: Réseau National d’Observation), the « French mussel watch », has revealed high PCB contamination at proximity of the Seine estuary including the bay of Seine. The present work is part of an interdisciplinary program including studies on the phytoplanktonic production, the hydrodynamic and the sediment dynamic in the Bay of Seine. The development and the validation of the present model for the bioaccumulation of PCBs in the blue mussel was carried out following a step by step approach: A deterministic model, based on ecophysiological data from the litterature on Mytilus edulis was developed. It can estimate the mussel trophic needs and its growth. This ecophysiological model was coupled with a bioaccumulation model. Validation of the coupled model was done using RNO’s data (concentration of CB153 in mussel) PCB contamination in estuaries and coastal areas in Europe The study site : The Bay of Seine C B 153 0 20 40 60 0 200 400 600 800 days ng.g-1 dw Villerville Le Moulard Port en Bessin Antifer C B 153 0 200 400 600 0 200 400 600 800 days ng.g-1 d w C B 153 0 50 100 150 200 0 200 400 600 800 days ng.g-1 d w CB 153 0 100 200 300 400 500 0 200 400 600 800 days ng.g-1 dw Size/A ge (Le M oulard) 0 20 40 60 0 200 400 600 800 days mm Size/Age (P orten B essin) 0 20 40 60 0 200 400 600 800 days mm Size/A ge (Antifer) 0 20 40 60 0 200 400 600 800 days mm Size/A ge (V illerville) 0 20 40 60 80 0 200 400 600 800 days mm Schematic structure of the blue mussel model PCB PCB TOTAL PARTICULATE MATTER Phytoplankton Detritic matter PIM FILTRATION TPM TEMP CONSUMPTION INGESTION ABSORPTION Shell weight x(2) Pseudofec es Feces Respiration SEFF AEPHY AEDET PCB Water PCB PCB flesh x(3) PCB Flesh Dry Weight x(1) RESULTS Ecophysiological model Bioaccumulation model 1 2 3 4 1 4 2 3 1 2 4 3 Good agreement has been obtained between calculated and measured concentrations of one of the most persistent PCB congeners (CB153) in mussels from the Bay of Seine (RNO).
