Formatted contents note Wetlands provide a variety of ecosystem services; however, they are at risk for various types of pollutants - heavy metal contamination from natural and anthropogenic causes, for example. The concentrations, trophic transfer, and biomagnification of non-essential heavy metals in water, algae, crustacean, and fish samples from two coastal barangays in the Sasmuan Pampanga Coastal Wetland were assessed as well as the human risks from the consumption of aquatic organisms that come from the area. Quantification of metal concentration was done through Inductively Coupled Plasma - Optical Emission Spectrometry (model - Shimadzu ICPE-9820), Bioaccusmulation through Bioaccumulation Factor (BAF), and Trophic Transfer through Trophic Transfer Factor (TTF). Human risks were assessed through surveys to obtain information on the respondent's commonly consumed organisms, frequency and amount of consumption, and commonly consumed parts, and comparison of the concentrations of heavy metals from the edibie parts to the permissible limits set by the Food and Agriculture Organization of the United Nations (FAO). The results showed that Pb has the highest concentrations of all the samples, while Cd and Hg had below detection values. Pb BAFs and TTFs indicated transfer of Pb in Water-Algae and Crustacean-Fish in Brgy. Mabuanbuan and Water-Algae, Algae-Fish and Crustacean-Fish in Brgy. Batang 2nd (P-value for both factors vs Sites >0.05). The average consumption of aquatic organisms is 2.94 and 2.54 kg, one to three times per week. The concentrations of heavy metals in the edible portion of samples analyzed did not exceed the permissibie limits set by FAO except for fish samples from Brgy. Batang 2nd. This indicates that the organisms pose little to no risk from consumption. Keywords: Biomagnification, Heavy Metals, Trophic Transfer, Wetlands.
