Abstract
Concentrations of heavy metal (Zn, Cu, Cd and Pb) were determined in muscle, gills and liver of 2 species (Rastrelliger kanagurta and Epinephelus areolatus) of marine fish purchased from Pasar Utama Bintulu. From this study, the heavy metals concentration in R. kanagurta were 23.67 µg/g dw (Zn), 0.35 µgig dw (Cu), 0.79 µgig dw (Cd) and 4.04 µg/g dw (Pb) for muscle; 172.19 µg/g dw (Zn), 0.57 µgig dw (Cu), 3.23 µgig dw (Cd) and 15.74 µg/g dw (Pb) for gills; 150.84 µgig dw (Zn), 3.50 µgig dw (Cu), 16.93 µgig dw (Cd) and 11.71 µg/g dw (Pb) for liver. While, the heavy metals concentration in E. areolatus were 19.49 µg/g dw (Zn), 0.24 µg/g dw (Cu), 0.17 µgig dw (Cd) and 6.23 µgig dw (Pb) for muscle; 92.94 µg/g dw (Zn), 0.52 µgig dw (Cu), 1.42 µgig dw (Cd) and 21.34 µg/g dw (Pb) for gills; 248.50 µg/g dw (Zn), 3.48 µgig dw (Cu), 5.01 µgig dw (Cd) and 4.16 µgig dw (Pb) for liver. Levels of metals Zn, Cu, and Cd in liver and gills for both of species were higher than those in muscle, while for Pb, concentrations showed the opposite trend only in liver of E. areolatus species. The variations in metal concentration and levels in fish from this present study compared to previous study might be related to many factors such as species, feeding habits, bioavailability of chemicals in food and water and physio-chemical parameters of the aquatic environment. The concentrations of Pb in muscle for both species studied were found to be exceeded the permissible limits set by Ministry of Health Malaysia. This condition can cause health problem to the consumer especially to human because of its toxicity.
