PFAS-free alternatives for sustainable applications: Sector-specific solutions and global perspectives.
Level 5 - mechanism / opinion, no new human data
Narrative review and framework analysis (by design analogy, not clinical CEBM)

What was done
The authors conducted a review assessing PFAS-free substitutes across multiple industries, including firefighting foams, textiles, food packaging, industrial surfactants, cosmetics, medical devices, and electronics. They evaluated chemical mechanisms, functional trade-offs, safety profiles, and market readiness, and applied a Driving forces-Pressures-State-Impacts-Responses (DPSIR) framework with sensitivity analysis to rank substitution urgency across sectors.
What was found
The abstract reports no numerical or experimental measurements. It presents a qualitative ranking of substitution urgency: very high for firefighting foams and food packaging; high for textiles and industrial surfactants; moderate-high for cosmetics and personal care products; moderate for electronics and semiconductors; and moderate/targeted for medical devices. The rankings remained stable across alternative weighting scenarios in sensitivity analysis, while persistent trade-offs were identified in durability, chemical resistance, and operational efficiency.
Why it matters
This review provides a structured prioritization framework to guide regulatory focus and industrial research investments toward the most urgent and viable PFAS replacements.
Limits
The abstract describes a narrative review and qualitative framework analysis rather than a systematic review or meta-analysis. No quantitative effect sizes, comparative bench-test data, or specific sample counts are reported. Evaluations of adoption barriers in low- and middle-income countries are conceptual.
