Abstract

"Improper disposal of toxic metals such as mercury Hg and lead Pb from transport and industrial activities can cause harmful environmental and biological effects. Hg contamination can damage the organ-systems. Meanwhile, Pb causes behavioral and learning problems, seizures and death. In Agusan Marsh, leaded gasoline is used by residents. In nearby areas, mining is present. Surveying and monitoring of toxic metal accumulation levels are to be taken seriously to ensure protection of wildlife in this ecologically significant wetland. For monitoring toxic metal accumulation, Kambu-ay Pila Ampullacea shells were collected in Masagansang Creek, a part of Agusan Marsh where livelihood activities occur. The shells were pounded and then subjected to Direct-Air-Acetylene Flame AAS and Cold Vapor AAS to determine the inherited levels of Pb and Hg, respectively. The shells were further tested for accumulation and elimination of these heavy metals under 50 mg L-set-up laboratory condition to determine if biosorption was still possible. Result showed that Kambu-ay shell contained 0.22 mg L of Hg and 220mg L of Pb. Further examination revealed that the shells were able to remove an average of 49.43 mg L of Pb and 43.88 mg L of Hg in laboratory set-up. The project's contribution is two-fold. First, Kambu-ay shell was proven to remove heavy metals. Second, the strong accumulation of contaminants by the shell is well suited for local monitoring programs. Caution should be taken if the meat of the shell is eaten. Continuous bioaccumulation of heavy metals in the food chain will threat Agusan Marsh's biodiversity. Thus, monitoring is necessary. by Jennyvi H. Papellero | Anthon Mark Jay A. Rivas | Bianca A. Munez | Farrah Leah U. Ebe | El Veena A.
