The content of polychlorinated biphenyls (PCBs) in aquatic organisms reflects a degree of pollution in the environment in which they live. in the present study, the concentration of PCB congeners was examined in freshwater bivalve molluscs (Anodonta complanata), bottom sediments and water from the lower Odra river. The bioconcentration factors (BCF) were lower than expected by about 30%. The BSAF in the mussel tissues exceeded the expected theoretical value (2.4) and ranged from 3.1 to 5.3. Mean PCB concentration in the mussels was highly correlated with the concentrations of these compounds in bottom sediments (r=0.82) and water (0.76).
