Assessment of the Accumulation of Trace Metals and Oxidative Stress Response Biomarkers in the Portunid Portunus segnis

The invasive blue crab Portunus segnis, which was collected from two sites on the Gulf of Gabès, is subject this work. This study based demonstrating accumulation capacity P. segnis by measuring concentrations cadmium, zinc, lead, and copper in gills hepatopancreas. enzymatic activities catalase, glutathione-S-transferase, reduced glutathione, lipid peroxidase were assessed region for first time. main results show that metals have high bioaccumulation potentials tissues between different sites. possible adaptation Gabès variations studied biomarkers metal at confirm usefulness as a sentinel species.
