The activity of superoxide dismutase (SOD), total protein as well as protein and SOD electrophoretic profiles in the digestive gland and the gills of the freshwater bivalve Unio tumidus at four localities of the River Sava (Jamena, Sremska Mitrovica, Šabac and Ostružnica) was examined. The specific SOD activity in the digestive gland of the U. tumidus was significantly higher in Jamena in respect to Šabac and Ostružnica. The different trend was obtained for the total SOD activity in the digestive gland, which was significantly increased in Sremska Mitrovica compared to investigated localities Šabac and Ostružnica. The total SOD activity in the digestive gland was also significantly higher in Jamena compared to Šabac, as well as in Šabac in respect to Ostružnica. The activity of total SOD in the gills of U. tumidus was significantly higher in Sremska Mitrovica in respect to Jamena and Šabac. The results obtained in our study show strong tissue and locality specificities, indicating different metabolic activities and various environmental influences. Our work also suggests, that the variations of SOD expression pattern in Unio tumidus could be used as a tool for the environment monitoring. Our study represents the first comprehensive report on SOD as a relevant oxidative stress biomarker in the freshwater bivalve Unio tumidus at different localities from the Sava River and provide the basis for future studies that will consider our reported parameters as potential biomarkers for biomonitoring of basal environmental conditions and some anthropogenic impacts.
