Regulating “forever chemicals”: social data are necessary for the successful implementation of the essential use concept
Science
8 Jun 2024 | Environ Sci Eur
Given the widespread persistence, mobility, and toxicity of many PFAS, a precautionary approach called the Essential Use Concept (EUC) is proposed, advocating for the phase-out of PFAS unless essential for health, safety, or critical societal functions. This paper discusses what broader societal perspectives are needed in the decision-making process to implement the EUC.
