Mercury (Hg) is a global pollutant that affect human and ecosystem health. It is transferred through trophic level and bio magnification in the food chain. In this study, total Hg was measured in the muscular tissue of samples of swordfish (Xiphias gladius) from different FAO fishing areas and imported in Italy between 2014 and 2017. Total mercury concentrations of muscular tissues were determined using cold vapour atomic absorption spectrometry. In order to assess the health risk associated with human consumption of this fish, the Hg intake values were calculated and compared with those of provisional tolerable daily intake (PTDI) (0.57 μg/kg b.w.) as fixed by the Food and Agriculture Organization/World Health Organization (FAO/WHO). The estimated PTDI (provisional tolerable daily intake) were lower for adults (0.40 μg/kg b.w./day) but not for children (0.97 μg/kg b.w./day), and therefore is considered to pose an alert for children with the present fish consumption volume.
汞（Hg）是一种全球性污染物，会影响人类和生态系统健康。它会通过食物链中的营养级传递和生物放大作用进行转移。本研究于 2014 年至 2017 年期间，在意大利进口的来自不同粮农组织捕鱼区的剑鱼（Xiphias gladius）肌肉组织样本中测量了总汞含量。使用冷蒸气原子吸收光谱法测定肌肉组织中的总汞浓度。为了评估人类食用这种鱼带来的健康风险，计算了汞摄入量值，并将其与粮农组织/世界卫生组织（FAO/WHO）规定的暂定可耐受每日摄入量（PTDI）（0.57μg/kg bw）进行了比较。对于成年人（0.40μg/kg bw/天），估计的暂定可耐受每日摄入量（PTDI）较低，但对于儿童（0.97μg/kg bw/天）则没有，因此，考虑到目前的鱼类食用量，儿童可能会受到警报。
