The pervasive presence of per and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals," in water systems poses a significant threat to both the environment and public health. PFAS are persistent organic pollutants that are incredibly resistant to degradation and have a tendency to accumulate in the environment, resulting in long-term contamination issues. This comprehensive review delves into the primary impacts of PFAS on both the environment and human health while also delving into advanced techniques aimed at addressing these concerns. The focus is on exploring the efficacy, practicality, and sustainability of these methods. The review outlines several key methods, such as advanced oxidation processes, novel materials adsorption, bioremediation, membrane filtration, and in-situ chemical oxidation, and evaluates their effectiveness in addressing PFAS contamination. By conducting a comparative analysis of these techniques, the study aims to provide a thorough understanding of current PFAS remediation technologies, as well as offer insights into integrated approaches for managing these persistent pollutants effectively. While acknowledging the high efficiency of adsorption and membrane filtration in reducing persistent organic pollutants due to their relatively low cost, versatility, and wide applicability, the review suggests that the integration of these methods could result in an overall enhancement of removal performance. Additionally, the study emphasizes the need for researcher attention in key areas and underscores the necessity of collaboration between researchers, industry, and regulatory authorities to address this complex challenge.
全氟和多氟烷基物质（PFAS），通常被称为“永久化学物质”，在水系中普遍存在，对环境和公众健康构成重大威胁。PFAS 是持久性有机污染物，极难降解，且有在环境中积累的倾向，导致长期的污染问题。本综述深入探讨了 PFAS 对环境和人类健康的主要影响，同时探讨了旨在解决这些问题的先进技术。重点是探索这些方法的功效、实用性和可持续性。该综述概述了几种关键方法，如高级氧化工艺、新型材料吸附、生物修复、膜过滤和原位化学氧化，并评估了它们在处理 PFAS 污染方面的效果。通过对这些技术进行比较分析，该研究旨在全面了解当前的 PFAS 修复技术，并深入了解有效管理这些持久性污染物的综合方法。虽然承认吸附和膜过滤由于其相对较低的成本、多功能性和广泛的适用性，在降低持久性有机污染物方面具有高效率，但该综述表明，这些方法的整合可能会整体提高去除性能。此外，该研究强调了研究人员在关键领域关注的必要性，并强调了研究人员、工业界和监管机构之间合作解决这一复杂挑战的必要性。
