[More] This article gives an overview of nanotechnologies applied in remediation of water contaminated by poly- and perfluoroalkyl substances (PFASs). The use of engineered nanomaterials (ENMs) in physical sorption and photochemical reactions offers a promising solution in PFAS removal because of the high surface area and the associated high reactivities of the ENMs. Modification of carbon nanotubes (CNTs) (e.g., oxidation, applying electrochemical assistance) significantly improves their adsorption rate and capacity for PFASs removal and opens a new door for use of CNTs in environmental remediation. Modified nanosized iron oxides with high adsorption capacity and magnetic property have also been demonstrated to be ideal sorbents for PFASs with great recyclability and thus provide an excellent alternative for PFAS removal under various conditions. Literature shows that PFOA, which is one of the most common PFASs detected at contaminated sites, can be effectively decomposed in the presence of either TiO2-based, Ga2O3-based, or In2O3-based nano-photocatalysts under UV irradiation. The decomposition abilities and mechanisms of different nano-photocatalysts are reviewed and compared in this paper. Particularly, the nanosized In2O3 photocatalysts have the best potential in PFOA decomposition and the decomposition performance is closely related to the specific surface area and the amount of photogenerated holes on the surfaces of In2O3 nanostructures. In addition to detailed review of the published studies, future prospects of using nanotechnology for PFAS remediation are also discussed in this article.

[More] To extract perfluoroalkane sulfonamides (PFASAs) in water and urine samples effectively, a new adsorbent based on poly (1H,1H,2H,2H-nonafluorohexyl acrylate/vinyboronic anhydride pyridine complex-co-ethylenedimethacrylate) monolith (FBE) was synthesized and used as the extraction phase of multiple monolithic fiber solid-phase microextraction (MMF-SPME). Because there are abundant fluorinated (F-) alkyl chains and boron atoms in the adsorbent, the FBE/MMF-SPME displays satisfactory extraction performance for PFASAs by means of fluorophilic and B-N coordination interactions. Under the most favorable conditions, the FBE/MMF-SPME was combined with HPLC-MS/MS for the sensitive monitoring of ultra-trace PFASAs in environmental water and human urine samples. The limits of detection and limits of quantification achieved for target analytes were in the range of 0.13-1.45 ng/L and 0.44-4.80 ng/L, respectively. The developed FBE/MMF-SPME-HPLC-MS/MS method was successfully applied to quantify the level of PFASAs in water and human urine samples, and ultra-trace target PFASAs were detected in the real samples. The recoveries at different fortified concentrations ranged from 80.3% to 119% with RSD in the range of 0.9-11%. Compared with reported methods, the proposed method exhibits some merits such as high sensitivity, good method precision, low consumption of sample and environmental friendliness.

Determining global background soil PFAS loads and the fluorotelomer-based polymer degradation rates that can account for these loads

Authors: Washington, JW; Rankin, K; Libelo, EL; Lynch, DG; Cyterski, M (2019) Science of the Total Environment 651:2444-2449. HERO ID: 5080393

[More] In recent years, fluorotelomer-based polymers (FTPs) have been the dominant product of the fluorotelomer industry. For the last decade, whether FTPs degrade to toxic perfluorocarboxylates (PFCAs) has been vigorously contested, with early studies arguing that FTPs have half-lives >1000 years, and others concluding decadal half-lives. Given this FTP half-life discrepancy of 10- to >100-fold, here we investigate whether environmental loads of long-chain PFCAs might offer an independent approach to assess FTP half-lives. Specifically we: i) use surface soil-PFCA data to estimate terrestrial surface-soil background PFCA concentrations and loads; ii) extrapolate these data to generate global PFCA load estimates; iii) compare these estimates to published ocean-derived and industrial-emissions load estimates, finding agreement for perfluorooctanoate (C8), but an excess in longer-chain (C10,C12) PFCAs for ocean- and soil-derived loads relative to emissions; iv) model FTP degradation rates required to reconcile this discrepancy; and iv) compare our modeled estimates to existing experimental results. These findings show agreement for FTP half-lives at the decades-scale supporting existing laboratory studies that report decade-scale half-lives for FTPs. This suggests that global long-chain PFCA loads will increase for decades if legacy FTPs already manufactured are not contained upon disposal. These results suggest that FTPs comprised of novel poly- and perfluorinated alkyl substances (PFASs) now in production might constitute considerable sources to the environment of the new generation of PFASs.
