| Popis: | Freshwater mussels, Anodonta cygnea L., were collected in a lowly polluted area in north-eastern France, and exposed during 28 days at three sites up and downstream of a chlorine bleached pulp and paper mill effluent. Water, sediment and mussel samples were collected at regular intervals and analyzed for halogenated organic residues using the sum parameters AOX (Adsorbable Organic Halogen) and EOX (Extractable Organic Halogen). The survey of the water showed a chronic contamination by organic halogens of the water and the sediment downstream of the pulp and paper mill sewer. Mussels exposed upstream of the mill showed no significant variation of their EOX tissue concentration. In contrast, progressive accumulation of EOX occurred with the exposure time in mussels exposed downstream of the mill. No steady state of the EOX concentration was observed after four weeks of exposure. |
