Abstract
This study was to determine the
level of Zinc (Zn) and Lead (Pb) in the muscle and gills of fishes in
Balok River, Pahang, Malaysia. Four different species of fishes:
Megalops cyprinoides, Johnius trachycephalus, Lates calcarifer and
Hexanematichthys sagor were digested using acid digestion method and
analysed by Inductive Coupled Plasma Micro Spectrometer (ICP-MS). Pb
levels in muscle among all fish species occurred in the rank order: H.
sagor > L. calcarifer>M. cyprinoides> J. trachycephalus
meanwhile Pb level in gills: Johnius trachycephalus> L.
calcarifer> H. sagor > M. cyprinoides. Pb concentration in muscle
of fish was the highest in H. sagor (0.037±0.037mg/kg) and in gill of
J. trachycephalus with value of 0.213±0.273mg/kg respectively.
Meanwhile Zn level among all fishes were in order of: H.sagor>
J.trachycephalus> L.calcarifer> M.cyprinoides. The mean
concentration of Zn in muscle and gill of H.sagor was the highest
(2.400±1.677 and 31.572±4.562mg/kg) compared to other species
respectively. However, the concentration of Pb and Zn in all fish
samples were below permissible limit according to Malaysia Food Act
(MFA, 1983), US Food and Drug Administration (USFDA, 1993), European
Commission (EC, 2001), Food and Agriculture Organization (FAO, 2012) and
were estimated safe for human consumption.
