Accumulation of mercury and lead were analysed in seven tropical seagrass species: Enhalus acoroides, Halophila minor, Halophila spinulosa, Halophila ovalis, Thalassia hemprichii, Halodule uninervis and Cymodocea serrulata at Pulai Estuary, Johor Straits, Malaysia. Analyses of all seagrass samples were carried out using Perkin Elmer Atomic Absorption Spectrophotometer Model AAnalyst 400 and Pearson’s correlation coefficients of metal concentrations were determined using SPSS version 16. The concentrations of Hg and Pb in different tissues of the seagrass are in the range of 0.1–69 μg\gDW and 81–249 μg\gDW respectively. There are significant correlations between the accumulation of Pb in roots rhizomes, rhizomesleaves and leaves–roots for Enhalus acoroides, Halophila minor, Halophila ovalis, Thalassia hemprichii and Halodule uninervis. Meanwhile for Hg, there are significant correlations among plant parts for Halophila ovalis. Halophila ovalis shows ability in translocation of metals and is capable to absorb metals at high concentration. Therefore Halophila ovalis is selected as the best bioindicator.
