Heavy metals in seafood from Pasar Payang

Abstract

This study was to investigate the contamination of heavy metals in commercially important seafood. The aim of this study is to provide information on the Cd, Cu, Fe, Pb, Mn and Zn levels in the muscle, and fish gill for seven samples (Mega/aspis cordyla, Nemipterus furcosus, Rastrel/iger kanagurta, Decapterus macrosoma, Curangoides caeruleopinnatus, Lutjanus lineolatus, Atule mate ), and compare the heavy metals contain in these two tissues. Heavy metals concentration in squids (Loligo spp) and prawns (Penaeus merguiensis, Penaeus semisulcatus) also determine in this study. The seafood samples collected from Pasar Payang. All seafood samples have Cd, Cu, Pb, and Zn in the range of 0.09 - 2.97 μgig, 1.15 - 9.67 μg/g, 0.03 - 3.07 μgig, and 16.86 - 55.18 μgig respectively. These heavy metals ranged were below the maximum allowable level provided by F AO (2007). Whereas there are no recommended maximum level from F AO for Fe and Mn, the range for Fe were 10.03 - 475.83 μgig, and for Mn were 0.70- 14.90 μgig form this studied. This studied also showed that gills accumulated higher heavy metals concentration compare to fish muscles.
