A metabolic model was used to predict the accumulation of 137Cs in plaice Pleuronectes platessa L. Model verification was carried out using published results on the accumulation of 137Cs from in situ measurements, and from experimental studies. Uncertainty analysis was performed in order to determine the contribution from the separate model parameters to the total uncertainty for the exposure pathways food and water, respectively, and for the body burden of 137Cs in fish. Altogether 70% of the predicted body burden was due to intake from food. Generally, data regarding the metabolic regulation of 137Cs in the gills are loosely supported and creates a large variation in the final outcome i.e., the concentration of 137Cs in the fish. The two next important parameters contributing to the variation in body burden were the concentration of 137Cs in the food, and the exponent relating metabolism to body weight. |
