This study aimed to investigate the levels of heavy metal contamination in fish samples, to compare the concentration with a standard guideline, and to assess the associated human health risks through the consumption. Nine fish species, Spratelloides gracilis, Decapterus macarellus, Nemipterus japonicus, Atule mate, Selar crumenophthalmus, Epinephelinae, Euthynnus affinis, Rastrelliger kanagurta, and Selaroides leptolepis were collected from main local fisheries, Fisheries Development Authority of Malaysia (LKIM) Kuantan, Pahang. The essential and toxic heavy metals, namely copper (Cu), iron (Fe), zinc (Zn), arsenic (As), cadmium (Cd), and lead (Pb) were undergoes wet acid digestion and analyzed using analytical techniques, Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The hierarchy of the concentration of heavy metal in fish samples is Fe >Zn > Cu > Pb > As > Cd. The concentration heavy metals in fish samples were compared with permissible limit set by World Health Organization (WHO), Food and Agriculture Organization (FAO), and Malaysia Food Act and Regulation (MFA). The results showed that some of the fish samples had higher concentrations of these heavy metals in the fish tissues, which exceeding permissible limits. A human health risk assessment was carried out using Estimated Daily Intake (EDI) and Target Hazard Quotient (THQ) formulas to evaluate the possible risk associated with the consumption of contaminated fish. Therefore, public awareness initiatives are recommended to educate communities about the potential health risks associated with consuming contaminated fish.
