Human exposure to highly nickel-polluted environments through oral ingestion pathways may cause various pathological effects. This biomonitoring study aimed to assess the human health risk of potentially toxic nickel in 19 species of marine fishes from Setiu (Terengganu) and two popular seafood mollusks (mangrove snail Cerithedea obtusa and cockle Anadara granosa) from the coastal area of Peninsular Malaysia. The Ni levels of the three seafood types were found below the maximum permissible limit for nickel. The nickel target hazard quotient values of all seafood were lower than 1 for average and high-level Malaysian consumers, indicating nickel’s non-carcinogenic risk of seafood consumption. It was also found that the calculated values of estimated weekly intake were below than established provisional tolerable weekly intake of nickel for both average and high-level consumers. It can be concluded that the average consumption of seafood would not pose adverse effects of nickel to the consumers although the questionable target cancer risk of nickel was considered unacceptable. This study provided a scientific basis for the food safety assessment of nickel and suggestions for risk management of seafood consumption in Malaysia.
