【 摘 要 】

Mercury is a toxic heavy metal element that can damage embryo development. Although this element is highly toxic, some human activities such as mining and industries are still using it. The uncontrolled usage of this element leads to pollution problem in the environment, which includes the seagrass ecosystem in the coastal area of Seribu Islands. For that, to gather more information about mercury pollution in the seagrass beds of these islands, the concentration of mercury (Hg) was measured in sediment, rhizomes, roots and leaves of two species of seagrass (Enhalus acoroides and Thalassia hemprichii) from Lancang Island, Pari Island and Panggang Island at Seribu Islands, Indonesia in April-May 2017. The highest concentration of mercury was found in sediment on Lancang Island. The concentration of mercury was significantly higher on leaves compare to on roots or rhizomes in E. acoroides on Lancang Island and Panggang Island. T. hemprichii accumulate mercury higher than E. acoroides on Lancang Island. Overall, mercury accumulation on both species ranges at 7.12 - 87.41 ug/kg dw and this shows that they have the potential as bio-indicator of mercury bio accumulation.
