Trace elemental levels were determined by inductively coupled plasma-mass spectrometry in muscle, eggs and sperm of 23 Thunnus thynnus fishes collected from May to August 2013 in the Mediterranean Sea. Zn, Mn, Fe, Cu, Cr, Ni and Se content was compared with Recommended Daily Allowances. Cd, Hg and Pb concentrations were below the maximum limits fixed by the European Legislation. Tuna food safety was evaluated considering Tolerable Weekly Intake (TWI) or Provisional Tolerable Weekly Intake for As, Hg, Cd and Pb. Only BMDL01 data for As and Pb were calculated as established by the Joint FAO/WHO Expert Committed on Food Additives. The daily consumption of fresh tuna ensures a good intake of these elements. None of the tested samples surpassed the European maximum limits. Cd, Hg and Pb remained within safety margins, while As is slightly higher than the provisional TWI.
采用电感耦合等离子体质谱法测定了2013年5月至8月在地中海采集的23条蓝鳍金枪鱼的肌肉、鱼卵和精子中的微量元素含量。将锌、锰、铁、铜、铬、镍和硒的含量与推荐每日摄入量进行了比较。镉、汞和铅的浓度低于欧洲法规规定的最高限量。考虑到砷、汞、镉和铅的每周耐受摄入量（TWI）或暂定每周耐受摄入量，对金枪鱼的食品安全进行了评估。仅按照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的规定计算了砷和铅的BMDL01数据。新鲜金枪鱼的日常消费能确保这些元素的良好摄入量。所有测试样本均未超过欧洲最高限量。镉、汞和铅仍在安全范围内，而砷略高于暂定每周耐受摄入量。
