The accumulation profiles of nine perfluoroalkyl substances (PFASs) were determined in 95 muscle samples of seven freshwater (n = 65) and seven marine (n = 30) fish species collected in Northern Vietnam. In both groups of fish, perfluorooctane sulfonic acid (PFOS) was the most prevalent component, accounting for roughly 29 % of total PFASs. The total PFASs in freshwater fish species ranged from 0.08 to 8.06 ng/g wet weight (w.w), with the highest concentration found in topmouth culter (7.01 ± 1.23 ng/g w.w). In marine fish, the highest mean concentration of PFASs was detected in Asian sea bass (2.75 ± 0.54 ng/g, w.w). Estimation on the human dietary intake of PFASs from fish consumption resulted in hazard ratios (HR) ranging from 0.019 to 0.238 for freshwater fish and from 0.016 to 0.074 for marine fish, indicating low exposure risks associated with PFASs.
本研究在越南北部采集了 95 份淡水（n=65）和 7 份海水（n=30）鱼类肌肉样本，分析了 9 种全氟烷基物质（PFASs）的积累情况。在这两组鱼类中，全氟辛烷磺酸（PFOS）是最常见的成分，约占总 PFASs 的 29%。淡水鱼中 PFASs 的浓度范围为 0.08-8.06ng/g 湿重（w.w），翘嘴红鲌的浓度最高（7.01±1.23ng/g w.w）。在海鱼中，PFASs 的平均浓度最高的是亚洲羊头鲷（2.75±0.54ng/g w.w）。通过鱼类消费估算的全氟烷基物质（PFASs）对人体的膳食摄入量，其危害比（HR）范围在 0.019 至 0.238（淡水鱼）和 0.016 至 0.074（海水鱼）之间，表明与 PFASs 相关的暴露风险较低。
