Two cultured marine fish, the Japanese seabass (Lateolabrax japonicus) and red seabream (Pagrus major) were collected from eight fish cage sites along the coast of Fujian province in China. The concentrations of Ag, As, Cd, Co, Cu, Fe, Mn, Se, and Zn in their muscle, stomach and liver tissue were quantified. The risk of these trace elements to humans through fish consumption was then assessed. The highest concentrations of As, Cd, Se and Zn in fish feed from fish cages were found in Dongshan Station. Moreover, the As levels in the muscles of both species at all sites were generally higher than China's national standard (>1.0 microg/g). Trace element concentrations in two marine fish followed the order of livers > stomachs > muscles. Although the As levels in two marine caged fish exceeded the permissible standards, the estimated daily intake of As did not exceed the reference dose guideline established by US EPA. For other trace elements examined in this study, their concentrations did not exceed the permissible concentrations of the international standards.
从中国福建省沿海的 8 个网箱养殖区采集了两种养殖海水鱼，即日本真鲈（Lateolabrax japonicus）和红鳍东方鲀（Pagrus major）。定量分析了其肌肉、胃和肝组织中 Ag、As、Cd、Co、Cu、Fe、Mn、Se 和 Zn 的浓度。然后评估了通过食用这些鱼类摄入这些微量元素对人类的风险。在东山站的网箱养殖鱼饲料中发现了最高浓度的 As、Cd、Se 和 Zn。此外，所有地点两种鱼类的肌肉中的 As 水平通常高于中国国家标准（>1.0μg/g）。两种海水鱼中的微量元素浓度按肝脏>胃>肌肉的顺序排列。尽管两种网箱养殖海水鱼中的 As 水平超过了允许标准，但 As 的日摄入量估计并未超过美国环保署制定的参考剂量指南。对于本研究中检查的其他微量元素，其浓度没有超过国际标准规定的允许浓度。
