The study was conducted to determine the phytoremediation potentials of some mangrove species inside a mine site of Platinum Group Metals Corporation (PGMC) in Claver, Surigao del Norte. For comparison purposes, a separate mangrove forest located at Nasipit, Agusan del Norte (ADN) free from mining activities was also studied. Plant tissues of the three species with the highest SIV in both study sites were analyzed using Microwave Plasma-Atomic Emission Spectrometer and Acid Digestion. Lumnitzera racemosa, L. littorea and Quassia indica had the highest importance values at PGMC and Avicennia officinalis, L. racemosa, and Ceriops tagal at Nasipit, ADN. The two sites differ in species composition manifested by low similarity index. Quassia indica at PGMC and C. tagal at Nasipit, ADN exhibited characteristics of a hyperaccumulator for Molybdenum, Manganese, Lead, Chromium and Nickel. L. racemosa, L. littorea and A. officinalis were possible excluders of Molybdenum, and A. officinalis was a probable indicator of Lead. Salinity is highly encouraged for inclusion in studies of this kind as it also affects species composition, while verification studies should be conducted to validate the results of the study on the phytoremediation potentials of the species examined due to antagonistic and synergistic behaviors of heavy metals.
