Malaysians are the highest seafood consumers in the region; be it fresh or processed. Environmental pollution has put the safety of seafood at stake, heavy metals among others. This study was done to assess the health risk associated with selected heavy metals ingestion from processed seafood.,The most preferred processed seafood type and the intake rates were determined from a cross-sectional survey among communities in Shah Alam, Selangor (n = 90). The processed seafood were then purchased from local traders (n = 81), underwent homogenization, acid digestion (0.5 g) in Multiwave 3,000 and heavy metal quantitation (Hg, Pb, Cd, As) using ICP-MS. Estimated weekly ingestion (EWI), hazard quotient (HQ), hazard index (HI), lifetime cancer risk (LCR), and target risk (TR) were used to estimate the risk associated with processed seafood consumption.,Arsenic was the highest metal detected, acetes topping the list (10.05 ± 0.02 mg/kg). Mercury was detected at significantly higher level in salted fourfinger threadfin (0.88 ± 0.09 mg/kg) while Pb and Cd in toli shad (2.67 ± 0.16 mg/kg; 0.32 ± 0.22 mg/kg). Non-cancer risk was estimated for consumption of dried/salted food types with hazard index (HI) anchoives (5.2) > salted fourfinger threadfin (1.8) > toli shad (1.7). Besides, an unacceptable cancer risk was estimated for all food types for continuous consumption (Total risk (TR) > 10–4), except the dried acetes.,This study implies that although the concentration of most heavy metals were well below the permitted value, significant amount of risk present for consumption of several species. In addition, for selected heavy metals such as Hg and As, speciation analysis followed by risk assessment would provide a clearer picture.,There is a need to refer back to the local permissible level of heavy metals in processed seafood and formulate safe consumption guide.,The food types are advised to be consumed with caution especially by the sensitive group.,This study estimated the risk of cancer and other non-cancer disease from processed seafood consumption among Malaysian women.

加工海鲜中的重金属污染和马来西亚女性的相关健康风险

马来西亚人是该地区海鲜消费量最高的人;无论是新鲜的还是加工过的。环境污染已经危及海鲜、重金属等的安全。本研究旨在评估与从加工海产品中摄入特定重金属相关的健康风险。最喜欢的加工海产品类型和摄入率是根据雪兰莪州莎阿南社区的横断面调查确定的(n = 90) . 然后从当地贸易商 (n = 81) 处购买加工过的海鲜,在 Multiwave 3,000 中进行均质化、酸消解 (0.5 g) 并使用 ICP-MS 进行重金属(Hg、Pb、Cd、As)定量。估计每周摄入量 (EWI)、危害商数 (HQ)、危害指数 (HI)、终生癌症风险 (LCR) 和目标风险 (TR) 用于评估与加工海鲜消费相关的风险。砷是检测到的最高金属,醋酸盐位居榜首(10.05 ± 0.02 mg/kg)。在盐渍四指鲱鱼中检测到的汞含量明显更高(0.88 ± 0.09 毫克/千克),而在鲱鱼中检测到的铅和镉(2.67 ± 0.16 毫克/千克;0.32 ± 0.22 毫克/千克)。非癌症风险估计为食用具有危害指数 (HI) 凤尾鱼 (5.2) > 盐渍四指鲱鱼 (1.8) > 鲱鱼 (1.7) 的干燥/盐渍食品类型。此外,除了干燥的醋酸盐外,所有持续食用的食物类型都估计有不可接受的癌症风险(总风险(TR)> 10-4)。本研究表明,尽管大多数重金属的浓度远低于允许值, 食用几种物种存在大量风险。此外,对于选定的重金属,如 Hg 和 As,
