Abstract

Lake Jarnsjon is located in Eman tributary, southern Sweden, and has in the past received wastewater from a paper mill using recycled paper contaminated with polychlorinated biphenyls (PCBs). Health of perch (Perca fluviatilis) was studied with physiological and morphological methods before and after removal of the PCB-contaminated sediment. Before the remedial activity, perch from the PCB-polluted Jarnsjon were morphologically characterized by gill and liver damage with small biochemical/physiological effects. An unexpected nonresponsiveness of perch liver EROD-CYP1A system was discovered. The results seem to indicate that PCB contamination alone cannot explain this observation. Two years after the removal of PCB, perch appeared healthy in Jarnsjon. However, some female perch from the lower region of Eman showed severe gonad anomaly. The results may indicate that these perch were affected by other activities in addition to the remedial activity in Jarnsjon.
