We determined concentrations of Hg, Pb, Cd, Cr, As, Ni, Ag, Se, Cu, and Zn in muscle tissue of six commonly consumed Long Island fish species (black seabass, bluefish, striped bass, summer flounder, tautog, and weakfish, total sample size = 1211) caught off Long Island, New York in 2018 and 2019. Long-term consumption of these coastal fish could pose health risks largely due to Hg exposure; concentrations of the other trace elements were well below levels considered toxic for humans. By combining the measured Hg concentrations in the fish (means ranging from 0.11 to 0.27 mg/kg among the fish species), the average seafood consumption rate, and the current US EPA Hg reference dose (0.0001 mg/kg/d), it was concluded that seafood consumption should be limited to four fish meals per month for adults for some fish (bluefish, tautog) and half that for young children. Molar ratios of Hg:Se exceeded 1 for some black seabass, bluefish, tautog, and weakfish.
我们测定了 2018 年和 2019 年在纽约长岛捕捞的六种常见食用鱼类（黑鲈、鲹鱼、条纹鲈、黄鳍鲷、鲈鱼和海鳟）肌肉组织中汞、铅、镉、铬、砷、镍、银、硒、铜和锌的浓度（总样本量为 1211 个）。由于长期食用这些沿海鱼类可能会导致汞暴露，从而对健康造成威胁；其他微量元素的浓度远低于被认为对人类有毒的水平。通过结合鱼类中测量的汞浓度（在不同鱼类中，平均值范围在 0.11 至 0.27 毫克/千克之间）、平均海鲜食用率以及美国环保署目前的汞参考剂量（0.0001 毫克/千克/天），可以得出结论，对于某些鱼类（如鲹鱼和鲈鱼），成年人每月应限制食用四餐海鲜，而对于儿童，则应减半。对于一些黑鲈、鲹鱼、鲈鱼和海鳟，汞与硒的摩尔比超过了 1。
