Commercially important marine fish, yellowfin tuna (YFT), and swordfish (SF), collected from the Indian Ocean around Sri Lanka were analysed for mercury (Hg) and cadmium (Cd) content. The ranges for Hg were < 0.07-1.60 and < 0.07-4.30 mg/kg, while for Cd < 0.006-0.134 and 0.006-0.180 mg/kg in YFT and SF, respectively. In SF 13.3% and in YFT 9.2% exceeded the 1 mg/kg limit for Hg, while 3.1% of YFT exceeded the 0.1 mg/kg limit for Cd. All other samples were well below the maximum limits. Human health risk assessment was investigated using Estimated Daily Intake, Total Hazard Quotient, Hazard Index, and Provisional Tolerable Weekly Intake values for Hg and Cd. The data indicated that the current YFT and SF consumption pattern in Sri Lanka poses no threat to consumer's health. However, further research and awareness on food safety aspects is needed on specific groups such as children and for areas in which consumption of seafood is high.
从斯里兰卡附近的印度洋中采集的商业上重要的海洋鱼类，黄鳍金枪鱼（YFT）和箭鱼（SF），分析了汞（Hg）和镉（Cd）的含量。Hg 的范围为<0.07-1.60 和<0.07-4.30 mg/kg，而 YFT 和 SF 中的 Cd 分别为<0.006-0.134 和 0.006-0.180 mg/kg。在 SF 中，有 13.3%的样本超过了 1mg/kg 的 Hg 限量，而 YFT 中则有 9.2%的样本超过了 0.1mg/kg 的 Cd 限量。所有其他样本均远低于最大限量。使用 Hg 和 Cd 的估计每日摄入量、总危害系数、危害指数和暂定可耐受每周摄入量值，对人类健康风险评估进行了调查。数据表明，目前斯里兰卡的 YFT 和 SF 消费模式不会对消费者的健康构成威胁。然而，对于儿童等特定群体以及海鲜消费较高的地区，需要进一步研究和提高对食品安全方面的认识。
