Determination of Selected Heavy Metal Contents in Fresh and Smoked Corbicula Fluminea (Muller, 1774) Collected from a Vendor in Kampung Kasar, Pasir Mas, Kelantan, Malaysia

Abstract

Smoked C. fluminea is most popular traditional snack in Kelantan. Kampung Kasar, Pasir Mas is one of the popular selling area for this traditional snack. Therefore, it is crucial to determine the heavy metal contents in “etak” tissue supplied by vendor in Kampung Kasar. Thus, this study aims to determine and evaluate the concentration of selected heavy metal (Cr, Zn, Mn and Cu) contents in fresh and smoked C. fluminea which were collected from a vendor in Kampung Kasar, Pasir Mas, Kelantan, Malaysia. Wet digestion method was used to extract the samples and tested with the air acetylene flame atomic absorption spectrometry (AAS). Result shows that, fresh C. fluminea has higher concentrations of heavy metals as compared to smoked C. fluminea processed by the vendor in all the measured parameters except for Cr. However, further assessment needs for cultural sustainability and safety consumption of smoked C. fluminea.
