The concentrations of total mercury (THg) in different organs of the Antarctic toothfish (Dissostichus mawsoni) collected from CCAMLR research blocks in Subarea 88.3 and Division 58.4.1 off the coast of Antarctica were determined. The results revealed THg concentrations of 0.165 ± 0.095 mg/kg (0.023-0.454 mg/kg, wet weight) in the Antarctic toothfish. In muscle, methyl mercury (MeHg) accounted for approximately 40% of the THg. In a comparison analysis, muscle and liver tended to bioaccumulate the highest levels of THg, and both THg and MeHg contents showed correlations with fish length and weight. Compared with international guidelines, fish contained 2.5-6.4% and 4.0-10.3% of the provisional tolerable weekly intake for THg recommended by the Joint FAO/WHO Expert Committee on Food Additives and the tolerable weekly intake for MeHg proposed by the European Food Safety Authority, respectively. These results suggest that consumption of the Antarctic toothfish presents no health risk to humans.
测定了从南极海岸88.3亚区和58.4.1分区的南极海洋生物资源养护委员会研究区域采集的南极犬牙鱼（南极 Dissostichus mawsoni）不同器官中的总汞（THg）浓度。结果显示，南极犬牙鱼体内的总汞浓度为0.165±0.095毫克/千克（湿重为0.023 - 0.454毫克/千克）。在肌肉中，甲基汞（MeHg）约占总汞的40%。在比较分析中，肌肉和肝脏往往生物累积的总汞水平最高，并且总汞和甲基汞含量均与鱼的长度和重量相关。与国际准则相比，这些鱼的总汞含量分别为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建议的暂定每周耐受摄入量的2.5 - 6.4%，以及欧洲食品安全局提议的甲基汞每周耐受摄入量的4.0 - 10.3%。这些结果表明，食用南极犬牙鱼对人类不存在健康风险。
