Zwitterionic, cationic, and anionic per- polyfluoroalkyl substances (PFAS) are increasingly reported in terrestrial aquatic environments, but their inputs to agricultural lands not fully understood. Here, we characterized PFAS 47 organic waste products (OWP) applied fields of France, including historical recent materials. Overall, 160 from 42 classes were detected target screening homologue-based nontarget screening. Target low agriculture-derived wastes such as pig slurry, poultry manure, or dairy cattle manure (median ∑46PFAS: 0.66 μg/kg dry matter). Higher levels urban industrial wastes, paper mill sludge, sewage residual household composts 220 μg/kg). Historical municipal biosolids (1976–1998) dominated by perfluorooctanesulfonate (PFOS), N-ethyl perfluorooctanesulfonamido acetic acid (EtFOSAA), cationic zwitterionic electrochemical fluorination precursors PFOS.

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.

Per- and polyfluoroalkyl substances (PFAS) are a diverse class of fluorinated anthropogenic chemicals that include perfluoroalkyl acids (PFAA), which widely used in modern commerce. Many products environmental samples contain abundant precursors can degrade into terminal PFAA associated with adverse health effects. Fish consumption is an important dietary exposure source for PFAS bioaccumulate food webs. However, little known about bioaccumulation precursors. Here, we identify quantify recreational fish species collected from surface waters across New Hampshire, US, using toolbox analytical methods. Targeted analysis paired water tissue suggests many below detection have higher potential than their PFAA.

At present, the defluorination of per- and polyfluoroalkyl substances (PFASs), including perfluoroether compounds as substitutes perfluorooctanoic acid (PFOA) perfluorooctanesulfonate, is limited by effective active species produced during oxidation-reduction process. The contribution hydrogen radical (•H) a companion substance in photoreduction electrocatalytic degradation PFASs has been neglected. Herein, we demonstrate that perfluorocarboxylic acids such PFOA hexafluoropropylene oxide dimer (GenX) underwent near-complete photodegradation continuously generating •H through perfluoroalkyl activation water under UV irradiation without any reagents catalysts. Importantly, initial dissolved oxygen, H+, impurities surface scarcely inhibited PFASs. difference mechanism between GenX action was elucidated combining theoretical calculations with targeted nontargeted analysis methods. investigation different indicates were not easily photodegraded via reduction compared other compounds, whereas polyfluorinated which some F atoms replaced Cl more prone to elimination. However, UV/•H system ineffective against perfluorosulfonic acids. This study provides an unprecedented perspective for further development removal technology design alternative are easy eliminate.
