| Abstract | Copper contamination by mining activities of CMI in soils and waters of Bgy. Mogpog,Marinduque should be addressed. There is a need to assess the area to identify organisms that have potential to rehabilitate copper contaminated waters and soils. This study aims to assess potential phytoremediators present in the Ino-Capayang Mine-made pond at Bgy. Mogpog, Marinduque. Three stations were established at the site. Copper concentrations in soil and water were determined, as well as other abiotic parameters such as pH, DO, COD, TSS and temperature. Microalgal samples were collected using plankton net and were identified. Importance Values (IV) of dominating plant species at the stations were determined. The study revealed 12 identified taxa of microalgae in water. Diatoms dominated the microalgal community, accounting for 70% of the overall total cell abundance. Station 3 had the most number of algal taxa. However, the microalgal diversity is low, which can be attributed to the presence of copper (mean of 0.097 ppm) and high TSS in the water. On the other hand, there is an immediate need to remediate the soil in the area since copper concentration in the sites were significantly higher in soil (663.78 ppm) than in water (0.097 ppm). The pH concentrations were also relatively acidic in soil than in water. A total of 27 species belonging to 19 genera from 11 families were recorded under the division Ancerophyta. Under division Pteridophyta, a total of 3 species belonging to 3 genera from 3 families were recorded from the sampling site. Among the angiosperm families observed, the most represented families were Poaceae (5 spp.), Compositae (4 spp.), Leguminosae (4 spp.), Convulvulaceae (4 spp.) and Cyperaceae (3 spp.). Among the identified grass species that are capable of dominating the site are: Bamboo (IV=0.40), followed by Synedrella nodiflora (IV=0.36), Axonopus compressus (IV=0.36), Mimosa pudica (IV=0.35), and the 5th in rank is Poaceae sp. 1. The high Importance Values of these plant species revealed its capability to tolerate soils with high copper concentration, hence can be potential phytoremediators in the area. |
