| Abstract | Seagrasses have a high bioaccumulation capacity because they interact directly with the water column through the leaves and with sediment through the roots and rhizomes. Therefore they can be used as good bioindicator. The aims of this study were to analyze the heavy metal concentration of Pb and Cd in sea water and sediment as well as on the organs of Thalassia hemprichii including roots, rhizomes and leaves, potentially as phytoremediator agent. Samples were taken from two coastal waters in Ambon Island, namely Suli and Poka waters. The heavy metal content of Pb and Cd was analyzed in water, sediment and seagrass organ using Atomic Absorption Spectrophotometer. The results showed that the concentrations of Pb and Cd were higher in sediments (0.135 to 0.309 ppm/Pb and 0.107 to 0.190 ppm/Cd) than in water (0.013 to 0.084 ppm/Pb and 0.032 to 0.071 ppm/Cd). The highest metal concentration of Pb and Cd was detected at the roots of 0.579 ppm (Pb) and 0.363 ppm (Cd), then on leaves with values of 0.451 ppm (Pb) and 0.275 ppm (Cd). The concentrations of Pb and Cd were higher in seagrass than in water and sediments indicating that seagrass T. hemprichii has a good accumulator capability, indicated by a bioconcentration factor (BCF) value greater than 1 and potentially as a phytoremediator agent of heavy metals Pb and Cd. |
