Key Points

Incomplete biodegradation of fluorine-free foams was observed under both aerobic and anaerobic conditions, which raises environmental concerns.
The study identified redox-specific byproducts resulting from the degradation process, impacting local ecosystems.
Observational analysis of microbial communities showed significant shifts due to the interaction with fluorine-free foams.
Understanding the degradation and byproduct formation is crucial for assessing the environmental impact of adopting these foams.

Implication

Study reveals incomplete biodegradation of fluorine-free foams in the environment, indicating shifts in microbial communities and byproduct formation.

Abstract

The phaseout of per- and polyfluoroalkyl substances (PFAS) in firefighting foams has motivated the adoption of fluorine-free foams (F3), yet their environmental fate remains poorly understood. This study provides the...
