Abstract

Per- and polyfluoroalkyl substances (PFAS) constitute a notorious category of anthropogenic contaminants, detected across various environmental domains. Among these PFAS, perfluoroalkyl acids (PFAAs) stand out as a focal point in discussions due to their historical industrial utilization and environmental prominence. Their extensive industrial adoption is a direct consequence of their remarkable stability and outstanding amphiphilic properties. However, these very traits that have made PFAAs industrially desirable also render them environmentally catastrophic, leading to adverse consequences for ecosystems. The amphiphilic nature of PFAAs has made them highly unique in the landscape of anthropogenic contaminants and, thereby, difficult to study. We believe that well-established principles from surface science can connect the amphiphilic nature of PFAAs to their accumulation and transport in the environment. Specifically, we discuss the role of interfacial science in describing the stability, interfacial uptake (air–liquid and solid–liquid), and wetting capability of PFAAs. Surface science principles can provide new insights into the environmental fate of PFAAs, as well as provide context on their deleterious effects on both the environment and human health.

从表面科学角度看环境中的全氟烷基酸 (PFAAs)
全氟烷基和多氟烷基物质(PFAS)是一类臭名昭著的人为污染物,在各种环境领域都有发现。在这些 PFAS 中,全氟烷基酸(PFAAs)因其历史上的工业用途和突出的环境问题而成为讨论的焦点。全氟烷基酸之所以被工业界广泛采用,直接原因是它们具有显著的稳定性和出色的两亲性。然而,正是这些特性使全氟辛烷磺酸成为工业上的理想物质,同时也使其成为环境灾难性物质,对生态系统造成不利影响。全氟辛烷磺酸的两亲性质使其在人为污染物中显得非常独特,因此很难对其进行研究。我们认为,表面科学的既定原理可以将全氟辛烷磺酸的两亲性与其在环境中的积累和迁移联系起来。具体来说,我们讨论了界面科学在描述全氟辛烷磺酸的稳定性、界面吸收(空气-液体和固体-液体)和润湿能力方面的作用。表面科学原理可以为了解全氟辛烷磺酸的环境归宿提供新的视角,并为了解其对环境和人类健康的有害影响提供背景资料。
