Metal accumulation in the marine environment can increase the metal content of fish living in it. For this reason, it is essential to evaluate the nutrition from fish consumption and assess metal toxicity risk. Ten species of demersal fish, which are part of the daily diet of coastal residents, were sampled using trammel net in the East China Sea. Levels of the microelements, the constant elements, and the toxic elements of muscle tissue were analyzed. Spiny red gurnard had the highest concentrations of calcium, copper, and iron, whereas pufferfish and threadfin porgy were good sources of zinc and magnesium. The levels of lead, cadmium, and inorganic arsenic in all samples were below the limit values according to Chinese national standards. Although some concerns were raised about the concentration of mercury (Hg) in threadfin porgy, silver croaker, and fivespot flounder, molar ratios (selenium, Se:Hg) and the Se health benefit values (HBV) indicated that they were safe for human consumption. Additionally, the estimated weekly intake and % weekly contribution of 10 fish species with different elements were provided, giving a reference for the people's healthy consumption.
海洋环境中的金属积累会增加生活在其中的鱼类的金属含量。因此，评估鱼类消费的营养价值和评估金属毒性风险至关重要。本研究采用三重网在东海采集了 10 种底栖鱼类，这些鱼类是沿海居民日常饮食的一部分。分析了肌肉组织中的微量元素、常量元素和有毒元素。刺鲀的钙、铜和铁含量最高，而河豚和金线鱼是锌和镁的良好来源。所有样品中的铅、镉和无机砷含量均低于中国国家标准的限量值。尽管人们对金线鱼、银鲳和五条鰤中汞（Hg）的浓度表示担忧，但硒（Se）与汞（Hg）的摩尔比（Se:Hg）和硒健康效益值（HBV）表明它们可以安全食用。此外，还提供了 10 种不同元素的鱼类的每周估计摄入量和每周摄入量百分比（%），为人们的健康消费提供了参考。
