Cagayan River is the natural habitat of the endemic B. violacea (Clam) and this is also cultured in the pond at Cagayan State University-Aparri. Clams are among the healthiest seafood; thus, it is one of the target commodities for post-harvest technology since there are only a few processing techniques employed for this particular resource. However, it is important to know if this commodity is safe to utilize. Since clams are benthic filter feeders, they are meaningful indicators of the bioavailability of toxic contamination. This study attempted to determine the level of heavy metals, particularly Mercury and Cadmium in clams samples using a Cold Vapor Atomic Absorption Spectrophotometer and UV-VIS Spectrophotometer, respectively. Results of the study revealed that the concentrations of heavy metals such as mercury and cadmium in the tissue of B. violacea collected in the wild and the pond was within the allowable limit set by US EPA, WHO, and FDA. However, continuous consumption may lead to serious health problems for consumers. The researchers recommend to the local government unit of Lallo to utilize the results of this study as a basis to protect the public from the possible adverse effect of continuous consumption of the B. violacea. To enhance the quality of the river, strict implementation of solid waste management must be enforced especially in communities near the river.
