This study investigated the concentrations and profiles of 19 perfluoroalkyl substances (PFASs) in the muscle and liver of four freshwater species from Lake Trasimeno (Italy): (European eel), (goldfish), (European perch), and (red swamp crayfish). In livers, the amount of PFASs ranged from 3.1 to 10 µg kg, significantly higher than that in muscle (0.032-1.7 µg kg). The predominant PFASs were perfluorooctane sulfonic acid (PFOS) and long-chain carboxylic acids (C8-C14). Short-chain compounds (C4-C5), as well as the long-chain sulfonic acids (C9-C12), were not quantified. The contamination patterns were similar among species with few differences, suggesting the influence of species-specific accumulation. The PFAS concentrations in livers were comparable among species, while in muscle, the higher values were measured in European eel, followed by goldfish, European perch, and red swamp crayfish. The levels were generally lower than those reported for fish from Northern Italian lakes and rivers. The concentrations of regulated PFASs were lower than the maximum limits set by Regulation EU 2023/915 and did not exceed the Environmental Quality Standards (PFOS in biota). This study provides the first valuable insights on PFASs in freshwater species from Lake Trasimeno.
本研究调查了意大利特拉西梅诺湖4种淡水物种（欧洲鳗鲡、金鱼、欧洲鲈鱼和红沼泽螯虾）肌肉和肝脏中19种全氟烷基物质（PFASs）的浓度和分布情况。在肝脏中，PFASs的含量范围为3.1至10微克/千克，显著高于肌肉中的含量（0.032 - 1.7微克/千克）。主要的PFASs是全氟辛烷磺酸（PFOS）和长链羧酸（C8 - C14）。短链化合物（C4 - C5）以及长链磺酸（C9 - C12）未被定量。不同物种间的污染模式相似，差异较小，表明存在物种特异性积累的影响。肝脏中的PFAS浓度在不同物种间相当，而在肌肉中，欧洲鳗鲡的含量最高，其次是金鱼、欧洲鲈鱼和红沼泽螯虾。这些水平总体上低于意大利北部湖泊和河流中鱼类的报告水平。受监管的PFASs浓度低于欧盟法规2023/915设定的最大限值，且未超过生物群中PFOS的环境质量标准。本研究为特拉西梅诺湖淡水物种中的PFASs提供了首个有价值的见解。
