Concentrations in fish of per‐ and polyfluoroalkyl substances (PFAS) were reported for 7 deep lakes in the European subalpine area: Lakes Geneva, Lugano, Maggiore, Iseo, Como, Garda, and Mergozzo; one shallow lowland lake (Varese); and 2 high‐altitude alpine lakes (>2000 m a.s.l). Fillets and, in selected cases, other body fractions (viscera, liver, and residual carcass) from 8 fish species were analyzed. The possibility of harmonizing the monitoring protocols was tested. Results suggest that the sampling season is not critical for PFASs and the total protein content cannot be used for normalization of tissue concentrations because PFASs bind to specific proteins. Moreover, the polar lipid content could be used to reduce the variability of PFAS concentrations in phospholipid rich fractions of fish such as viscera and carcass. The data comparison and analysis show that the PFAS contamination in lake fish is generally correlated with the degree of urbanization of the lake catchment; however, it is sometimes difficult to compare absolute concentrations in lake fish because the lake hydro‐morphological characteristics play a substantial role in determining the chemical concentrations of persistent and mobile contaminants.

欧洲湖泊鱼类中的全氟和多氟烷基物质 (PFAS)：当前的污染状况、来源和监测前景

欧洲亚高山地区的 7 个深湖报告了鱼类中全氟和多氟烷基物质 (PFAS) 的浓度：日内瓦湖、卢加诺湖、马焦雷湖、伊塞奥湖、科莫湖、加尔达湖和梅尔戈佐湖；一个浅的低地湖（瓦雷泽）；和 2 个高海拔高山湖泊 (>2000 m asl)。分析了来自 8 种鱼类的鱼片以及在选定情况下的其他身体部分（内脏、肝脏和残留尸体）。测试了协调监测协议的可能性。结果表明，采样季节对 PFAS 并不重要，总蛋白质含量不能用于组织浓度的标准化，因为 PFAS 与特定蛋白质结合。此外，极性脂质含量可用于减少鱼类富含磷脂部分（如内脏和尸体）中 PFAS 浓度的变异性。数据对比分析表明，湖泊鱼类PFAS污染与湖泊流域城市化程度普遍相关；然而，有时很难比较湖泊鱼类的绝对浓度，因为湖泊水文形态特征在确定持久性和流动性污染物的化学浓度方面起着重要作用。环境毒理学化学2021；40：658-676。© 2020 SETAC
