Per‐ and Polyfluoroalkyl Substances (PFAS) in Subsurface Environments: Occurrence, Fate, Transport, and Research Prospect

Reviews of Geophysics, Journal Year: 2022, Volume and Issue: 60(3)

Published: Aug. 7, 2022

Abstract Per‐ and polyfluoroalkyl substances (PFASs), also known as “forever chemicals,” are manmade chemicals that have been increasingly detected in various geological settings since the early 2000s. The soil subsurface environments media commonly affected by PFAS. We conducted a comprehensive review of peer‐reviewed articles published from 2010 through 2022 concerning fate transport PFAS environments. This is organized into different subsections, covering basics properties how they affect occurrence, fate, PFAS, fundamental processes affecting mathematical models for describing predicting behaviors. Mechanisms governing environment, including sorption at air‐water interface, solid‐water nonaqueous phase liquids‐water were explored detail. Challenges future research priorities identified to better mitigate global challenges contamination.

Microbial and thermal treatment techniques for degradation of PFAS in biosolids: A focus on degradation mechanisms and pathways

Journal of Hazardous Materials, Journal Year: 2023, Volume and Issue: 452, P. 131212 - 131212

Published: March 15, 2023

Per- and polyfluoroalkyl substances (PFAS) are persistent organic chemicals detected in biosolids worldwide, which have become a significant concern for applications due to their increasing environmental risks. Hence, it is pivotal understand the magnitude of PFAS contamination implement effective technologies reduce prevent hazardous aftermaths. Thermal techniques such as pyrolysis, incineration gasification, biodegradation been regarded impactful solutions degrade transform into value-added products like biochar. These can mineralize compounds under specific operating parameters, lead unique degradation mechanisms pathways. Understanding pave way design technology optimize process conditions. Therefore, this review, we aim review compare thermal treatment incineration, smouldering combustion, hydrothermal liquefaction (HTL), biodegradation. For instance, perfluorooctane sulfonic acid (PFOS), firstly C-S bond cleavage occurs followed by hydroxylation, decarboxylation defluorination reactions form perfluoroheptanoic acid. In HTL, PFOS carried through OH-catalyzed series nucleophilic substitution reactions. contrast, involves three-step random-chain scission pathway. The first step includes cleavage, perfluoroalkyl radical, radical chain propagation Finally, termination produces very short-fluorinated units. We also highlighted important policies strategies employed worldwide curb biosolids.
