Fig. 1: Mean metal concentration in sediment, P. oceanica and C. nodosa leaves around El Kantaoui port Discussion and conclusions Seagrass is often considered as a useful metal bioindicator. This observation is confirmed by the present study. Indeed, comparison between concentrations of trace metals in two seagrass species and sediment show that P. oceanica may have a greater bioaccumulation capacity than sediment or C. nodosa (except for Cu). Acknowledgments The present study was funded by MAPMED project (I-B/2.1/395).
