Selected heavy metals content in commercial fishes at different season landed at Fisheries Development Authority of Malaysia Complex (LKIM) Complex, Kuala Terengganu, Malaysia
Fish is a common table food consumed by people for protein nourishment in Kuala Terengganu state. Therefore, a study was carried out to determine the bioaccumulation level of selected heavy metals; copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd) and lead (Pb) in muscle of four most popular and...

| description |
Fish is a common table food consumed by people for protein nourishment in Kuala
Terengganu state. Therefore, a study was carried out to determine the bioaccumulation level of
selected heavy metals; copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd) and lead (Pb) in muscle
of four most popular and landed fish species which are Nemipterus furcosus (Fork-tailed threadfin
bream), Katsuwonus pelamis (Skipjack tuna), Decapterus macrosoma (Shortfin scad) and Atule
mate (Yellowtail scad) which were caught at different season and landed at Fisheries Development
Authority of Malaysia Complex, Kuala Terengganu, Malaysia. A total of 30 individuals for each
species were collected during monsoon (December 2015) and non-monsoon season (September
2016). Concentrations of these heavy metals (Cu, Zn, As, Cd and Pb were determined by using
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) after 0.05 g of dried samples were
digested with 1.5 mL of Suprapur nitric acid. The average concentrations of Cu, Zn, As, Cd and
Pb for samples of non-monsoon season are 3.31±0.26 mg/kg dry wt., 14.9±2.68 mg/kg dry wt.,
9.12±3.45 mg/kg dry wt., 0.05±0.01 mg/kg dry wt. and 0.23±0.08 mg/kg dry wt., respectively. On
the other hand, the average concentration of the same metals in samples of monsoon season are
5.25±1.23 mg/kg dry wt. for Cu, 32.7±9.67 mg/kg dry wt. for Zn, 24.9±6.77 mg/kg dry wt. for
As, 0.11±0.07 mg/kg dry wt. for Cd and 0.66±0.21 mg/kg dry wt. for Pb, respectively. Generally,
the average metals concentrations in this study were below the permitted levels set by Malaysian
Food Act 1983 and Food Regulation 1985 except for As and Cd. However, the provisional tolerable
weekly intake (PTWI) have been calculated for each metals and found that the PTWI value for Cd in
K. pelamis caught during monsoon season was exceeded the permitted level set by FAO/WHO. This
study would be useful for creation of guidelines to protect the public from the harmful effects of the
toxicant present in the fish that is consumed by Kuala Terengganu people. |
