The present study investigates the concentrations of 14 trace and heavy metals (Ag, Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn, Hg, As, and Se) in two oceanic tuna species (Thunnus albacares and Katsuwonus pelamis) collected from the Tharuvaikulam fish landing centre along the Tuticorin coast, Southeast India, to evaluate potential health risks associated with their consumption. The analysis focused on the muscle, liver, gill, and skin tissues which were investigated using ICP-MS to assess the potential health risks associated with their metal accumulation. The concentration patterns of trace metals in the organs of T. albacares were found to be Se > Al > Fe > Zn > Cr > Cu > Mn > Ni > Pb > As > Hg > Cd > Co in muscle, skin, gill, and liver. In K. pelamis, a similar pattern was observed in skin, gill, and liver in the order of Se > Al > Zn > Fe > Cr > Cu > Mn > Ni > Pb > As > Hg > Cd > Co. Selenium (Se) had the highest Estimated Daily Intake (EDI) value in both Thunnus albacares (0.325 mg/kg bw/day) and Katsuwonus pelamis (0.036 mg/kg bw/day), both of which exceeded the Provisional Tolerable Weekly Intake (PTWI) set by the Joint FAO/WHO Expert Committee on Food Additives. Target Hazard Quotient (THQ) values for all toxic metals in tuna from the Tharuvaikulam region were below 1 for both children and adults, indicating no significant health risks and aligning with previous findings on tuna fish species. Nevertheless, ongoing monitoring of trace metal levels in seafood from this region is recommended to ensure continued consumer safety.
本研究调查了从印度东南部图蒂科尔恩海岸的塔鲁瓦伊库拉姆鱼类上岸中心采集的两种海洋金枪鱼（黄鳍金枪鱼和鲣鱼）中14种微量和重金属（银、铝、镉、钴、铬、铜、铁、锰、镍、铅、锌、汞、砷和硒）的浓度，以评估食用这些金枪鱼可能带来的健康风险。分析集中在肌肉、肝脏、鳃和皮肤组织上，使用电感耦合等离子体质谱法（ICP-MS）对这些组织进行研究，以评估与金属积累相关的潜在健康风险。在黄鳍金枪鱼的肌肉、皮肤、鳃和肝脏中，发现微量金属的浓度模式为硒＞铝＞铁＞锌＞铬＞铜＞锰＞镍＞铅＞砷＞汞＞镉＞钴。在鲣鱼的皮肤、鳃和肝脏中也观察到了类似的模式，顺序为硒＞铝＞锌＞铁＞铬＞铜＞锰＞镍＞铅＞砷＞汞＞镉＞钴。在黄鳍金枪鱼（0.325毫克/千克体重/天）和鲣鱼（0.036毫克/千克体重/天）中，硒的估计每日摄入量（EDI）值最高，两者均超过了联合国粮食及农业组织/世界卫生组织食品添加剂联合专家委员会设定的暂定每周耐受摄入量（PTWI）。来自塔鲁瓦伊库拉姆地区的金枪鱼中所有有毒金属的目标危害商（THQ）值对于儿童和成人均低于1，表明没有显著的健康风险，这与之前关于金枪鱼物种的研究结果一致。尽管如此，建议对该地区海产品中的微量金属水平进行持续监测，以确保消费者的持续安全。
