“…This study surveyed four locations of the ANI; Saheed Dweep (hereafter called as Neil Island Island), Swaraj Dweep (hereafter called as Havelock Island Island), Burmanallah and Haddo Bay situated on the southeast coast of ANI (Figure 1). These locations (except Haddo Bay) are tourism locations where in the dry season (October-April) a lot of touristic activities and the associated waste water discharge directly in to costal systems (Sachithanandam et al, 2022;VishnuRadhan et al, 2015). The Burmanallah location receives local untreated domestic waste water from the surrounding village Mishra & Mohanraju, 2018) The Haddo Bay receives anthropogenic input from the Portblair city along with waste discharges from the small industries (boat making, coloring, and dismantling industries) present along the bay (Sahu et al, 2013).…”

The bioindicator potential of seagrass ecosystems in coastal trace metal monitoring is low for tropical island ecosystems. This study evaluated the bioindicator potential of six seagrass species exposed to anthropogenic trace metal pollution in the Andaman and Nicobar Islands (ANI) of India. Sediment and seagrass biomass, samples were analyzed for trace metals (Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Zn) from four locations of ANI exposed to anthropogenic contamination. Geo accumulation Index values indicated moderate trace metal contamination in seagrass sediment. Seagrass trace metal accumulation from sediment was both species-specific and location- specific for ANI. Small seagrass species such as H. ovalis, H. beccarii and H. uninervis accumulated the maximum concentration of six trace metals (Cr, Cu, Fe, Ni, Pb, Zn) in their tissues compared to big seagrass species like T. hemprichii and E. acoroides of ANI. This study indicates leaves of small seagrass and roots of big seagrass species can serve as short- and long-term bioindicators respectively, of coastal trace metal contamination in tropical islands of ANI.
