Per- and polyfluoroalkyl substances (PFAS) pose great risks to human health the ecosystem, necessitating effective remediation strategies such as phytoremediation. Surfactants, due their ability increase bioavailability of hydrophobic contaminants, are considered potential agents improve phytoremediation for PFAS. In this research, we explored impact four surfactants (sodium dodecyl sulfate (SDS), rhamnolipid, Triton X-100, Glucopone 600 CS UP) on plant growth uptake PFAS by red fescue over 110 days. The results showed that while at lower concentrations did not negatively affect growth, highest dose (2,500 mg/kg) significantly reduced dry weight shoots. Although none led an increased overall removal efficiency ∑PFAS days, SDS enhance compounds with long carbon chain lengths. With addition 2,500 mg/kg, average fold increases were 1.99 perfluorooctanoic acid (PFOA), 2.44 perfluorononanoic (PFNA), 2.11 perfluorodecanoic (PFDA), 1.52 perfluoroundecanoic (PFUnA), 1.88 perfluorohexanesulphonic (PFHxS), 2.97 perfluorooctanesulfonic (PFOS). research indicated using surfactants, appropriate doses could effectiveness in mitigating long-chain PFAS, which is a known challenge soil remediation.

This study evaluates the reasons and factors making soil pollution by poly- perfluoroalkyl substances (PFASs) a wicked problem, reflecting upon nature, persistence, mobility, bioaccumulative properties of these compounds. The current regulation trends in production use such are also explored. highlights conflict between need for phasing out PFASs their indispensable role many strategic applications. We summarize knowledge on complex chemical to highly variable soils, mechanisms partitioning transport soil, exposure pathways humans. In particular, we focus that lead PFAS accumulation edible parts cultivated plants present some potential sustainable management practices could result risk mitigation environmental remediation actions. stemming from merging theoretical considerations pragmatic approaches mitigating problems related agricultural soils. highlight importance co-creation processes adoption solutions vast polluted areas make impacted populations discouraged, like being front an ‘untameable beast’, leading protests irrational behavior. our opinion, this might engage population more optimistic strategies tackle soliciting authorities stakeholders implement beyond actual practice supporting new policy development.

Increasing evidence is showing that per- and polyfluoroalkyl substance (PFAS) replacing compounds are not as safe they were assumed. This study investigated the plant uptake of two most prevalent PFAS, perfluorooctanoic acid (PFOA) perfluorooctane sulfonic (PFOS) their compounds, hexafluoropropylene oxide dimer (HFPO-DA or GenX) 6:2 chlorinated ether sulfonates (Cl-PFESAs) (6:2 Cl-PFAES) by hydroponically grown lettuce in presence different nitrogen fertilizers including ammonium sulfate ((NH4)2SO4), potassium nitrate (KNO3), urea a growth chamber. Interestingly, (NH4)2SO4 significantly increased GenX shoots ∼108% KNO3 PFOS Cl-PFAES 267% 395%, respectively, suggesting fertilizer type has marked impact on PFAS this was PFAS-dependent. Our results also showed generally resulted higher root to shoot transfer than other types fertilizers. Metabolomic analysis revealed amino acids, nucleotides, antioxidants major metabolites either decreased shoots. These fertilization management can have significant transport, depends compounds.
