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.

分析了从斯里兰卡周围印度洋收集的商业上重要的海水鱼，黄鳍金枪鱼（YFT）和箭鱼（SF）的汞（Hg）和镉（Cd）含量。在YFT和SF中，Hg的范围分别为<0.07-1.60 mg / kg和<0.07-4.30 mg / kg，而Cd <0.006-0.134和0.006-0.180 mg / kg。SF中的13.3％和YFT中的9.2％超出了汞的1 mg / kg限值，而YFT中有3.1％的镉超出了0.1 mg / kg限值。所有其他样品均远低于最大限量。使用估计的每日摄入量，总危害商数，危害指数以及汞和镉的暂定可耐受每周摄入量值调查了人类健康风险评估。数据表明，斯里兰卡目前的YFT和SF消费模式不会对消费者的健康构成威胁。然而，
