Minimizing human exposure to arsenic (As) and ensuring an adequate dietary intake of selenium (Se) are significant issues in research on food sources. This study measured the content of As and Se in the muscles, gills, liver, and gonads of the fish round goby () to assess the benefits and risks associated with their consumption. This was achieved by using dietary reference intake (DRI), estimated daily intake (EDI), target hazard quotient (THQ), and carcinogenic risk (CR). The elements were analyzed by atomic absorption spectrometry. The mean concentrations of As and Se (in μg kg wet weight) were 25.1 and 161.4 in muscle, 58.8 and 367.4 in liver, 47.4 and 635.3 in gonads, and 16.4 and 228.5 in gills, respectively. Arsenic in the muscle portion of fish accounted for up to 0.5% of the DRI, while Se constituted approximately 30% of the DRI. The EDI values were below the reference oral dose (RfD). The THQ were much below the permissible levels (THQ < 1), and the CR were at least within the permissible limit (CR < 10). With regard to the As content, round goby muscles can be deemed safe for consumers. They may also be a valuable source of Se in the human diet. However, round goby consumption should be monitored for the proper and safe intake of these elements.
尽量减少人类对砷（As）的接触并确保饮食中充足的硒（Se）摄入量是食物来源研究中的重要问题。本研究测定了圆腹雅罗鱼（）肌肉、鳃、肝脏和性腺中的砷和硒含量，以评估食用这些部位的益处和风险。这是通过使用膳食参考摄入量（DRI）、估计每日摄入量（EDI）、目标危害商（THQ）和致癌风险（CR）来实现的。通过原子吸收光谱法分析这些元素。砷和硒的平均浓度（以μg/kg湿重计）在肌肉中分别为25.1和161.4，在肝脏中为58.8和367.4，在性腺中为47.4和635.3，在鳃中为16.4和228.5。鱼肌肉部分的砷占膳食参考摄入量的0.5%，而硒约占膳食参考摄入量的30%。估计每日摄入量值低于参考口服剂量（RfD）。目标危害商远低于允许水平（THQ<1），致癌风险至少在允许限度内（CR<10）。就砷含量而言，圆腹雅罗鱼的肌肉对消费者来说可被视为安全的。它们也可能是人类饮食中硒的宝贵来源。然而，为了适当和安全地摄入这些元素，应该监测圆腹雅罗鱼的消费量。
