“Forever chemicals”: a sticky environmental problem

The discovery and widespread use of per- and poly-fluoroalkyl substances (PFAS) have exemplified the beneficial role of chemistry in modern life, yet they have also underscored significant environmental and health concerns. Termed “forever chemicals” due to their remarkable persistence, PFAS present formidable challenges in terms of contamination and toxicity. Efforts to address these challenges have led to the development of innovative degradation technologies, such as hydrothermal alkali treatment (HALT), low-temperature mineralization, and mechanochemical degradation, offering promising solutions to PFAS remediation. However, these advancements must be accompanied by robust investment in research, collaboration among stakeholders, and global responsibility to ensure effective management of PFAS contamination and mitigate its adverse impacts on ecosystems and human health.
