PESTAB. The bioconcentration data for seven chlorinated pesticides was determined in mussels (Mytilus edulis) and the relation of this data to solubility data was determined. A steady state approach was used in these experiments. Therefore, mussels were exposed to a given initial concentration of the pollutant in sea water aquaria. During accumulation of the substance, the decreasing concentration in the water was measured. The experiment was terminated after a constant concentration in the water was attained. Accumulation levels in mussels were determined and related to the steady state concentration in the water. The results of this study showed that mussels were suitable as a test animal in view of the good approach to equilibrium concentrations found in a short test period. This finding offers uncomplicated maintenance of the test organism and also makes the loss of test compounds by evaporation negligible in short periods. Moreover, mussels showed little capability of metabolic degradation. For highly volatile substances it is suggested that the usual dynamic system or a closed system be used.
