Per- and polyfluoroalkyl substances (PFAS) are found in a variety of industrial and household products. Human and wildlife exposure to PFAS is widespread. Increasing evidence suggests adverse effects of PFAS to human health and the environment. Human health risks from exposure through drinking water and fish consumption are areas of concern. Therefore, understanding occurrence and exposure risk is important to protect water resources. PFAS was investigated in fish fillet from the Delaware River over a 15-y period (2004-2018). The sample period coincided with actions to reduce or eliminate the release of certain PFAS to the environment. Elevated levels of perfluorononanoate (PFNA) and perfluoroundecanoate (PFUnA) were initially observed in tidal fish fillet. While significant decreases in PFNA and PFUnA concentrations were observed in fish fillet from the tidal river during the timeframe of the study, changes in concentrations of other PFAS in tidal and nontidal fish were less substantial. In 2018, fish fillet continued to be contaminated with perfluorooctanesulfonate (PFOS) at levels exceeding recommended regional risk advisory limits on fish consumption.

全氟和多氟烷基物质 (PFAS) 存在于各种工业和家用产品中。人类和野生动物广泛接触 PFAS。越来越多的证据表明 PFAS 对人类健康和环境有不良影响。通过饮用水和鱼类摄入接触 PFAS 对人类健康的风险是人们关注的领域。因此，了解其存在和暴露风险对于保护水资源非常重要。在过去的 15 年（2004-2018 年）中，对特拉华河的鱼片进行了全氟和多氟烷基物质 (PFAS) 的研究。采样期间恰逢采取行动减少或消除某些 PFAS 向环境的释放。最初在潮汐鱼片中观察到全氟壬酸 (PFNA) 和全氟十一烷酸 (PFUnA) 的含量升高。虽然在研究期间，潮汐河中鱼片中的 PFNA 和 PFUnA 浓度显著下降，但其他 PFAS 在潮汐和非潮汐鱼中的浓度变化则不那么明显。2018 年，鱼片中仍然持续受到全氟辛烷磺酸 (PFOS) 的污染，其含量超过了推荐的区域性鱼类消费风险咨询限制。《综合环境评估与管理》2021;17:411-421。©2020 SETAC。
