Foam fractionation of per- and polyfluoroalkyl substances (PFASs) in landfill leachate using different cosurfactants

Phong H. N. Vo et al.

Summary: Foam fractionation is an effective method to recover PFASs from aqueous sources, using the sorption of PFASs to the air-water interface of bubbles. The choice of cosurfactant plays a critical role in the effectiveness of foam fractionation. This study evaluates the effectiveness of four cosurfactants with different-charged headgroups and estimates the air-water interfacial partitioning of PFASs in the presence of these cosurfactants.

Occurrence of legacy and emerging poly- and perfluoroalkyl substances in water: A case study in Tianjin (China)

Yuna Li et al.

Summary: The study found that the concentration of PFAS in source water is relatively low, with a removal rate during treatment of only 11%, and long-chain PFAS have a higher removal rate than short-chain PFAS. Seasonal factors influence the total concentration of PFAS in water, but have a minor impact on the composition characteristics of PFAS. The detected PFAS concentrations in drinking water are within the recommended standards, posing no significant health risks.

Spatiotemporal distribution, partitioning behavior and flux of per- and polyfluoroalkyl substances in surface water and sediment from Poyang Lake, China

Aiping Tang et al.

Summary: This study examines the presence of legacy and emerging PFAS in surface water and sediments from Poyang Lake in China. The results show that emerging PFAS, such as HFPO-DA/TA, 6:2 and 8:2 Cl-PFESAs, 6:2 FTS, and OBS, are widely distributed in the lake, while legacy PFAS like PFOA and PFOS are less prevalent. The sediments in the lake are identified as an important long-term sink for these emerging PFAS. The study also identifies food packaging and textile treatments as the major sources of PFAS in Poyang Lake.

Summary: Although next-generation PFAS were designed as safer alternatives, there is limited evidence on their transformation and the safety of transformed products in the environment. In New Jersey soils, multiple congeners of one such PFAS alternative have been found, and potential reaction products were predicted based on analogous PFAS transformation pathways. However, no evidence of ether scission has been identified so far.

Titanium oxide improves boron nitride photocatalytic degradation of perfluorooctanoic acid

Lijie Duan et al.

Summary: Boron nitride (BN) has the property of degrading polyfluoroalkyl substances (PFAS) under UV-C irradiation. A composite material of BN and titanium oxide (TiO2) was created through calcination and showed enhanced photocatalytic activity for degrading perfluorooctanoic acid (PFOA) under UV-A. The composite material was found to facilitate charge carrier separation and degrade PFOA faster than TiO2 alone. Outdoor experimentation showed that the composite material could degrade PFOA in both deionized water and salt-containing water under natural sunlight.

Summary: This study investigated the spatial and vertical distribution of PFAS in different areas of an industrial city. The results showed higher concentrations of PFAS in farmland soils, indicating the impact of soil tillage. PFAS were found at higher levels in the shallow layer of soil profiles, with long-chain PFAS remaining in the topsoil and short-chain PFAS migrating to deeper soil layers. The application of F-enriched phosphorus fertilizers and atmospheric deposition were identified as important sources of F and PFAS in the soil.

Occurrence, distribution, and input pathways of per- and polyfluoroalkyl substances in soils near different sources in Shanghai

Qinghe Zhu et al.

Summary: This study investigated the concentrations and compositions of PFAS in soils near different potential sources in Shanghai. The results showed that the concentrations of PFAS varied among different locations, with the highest concentrations near the fire station. PFAS in soils were mainly composed of short-chain perfluoroalkyl carboxylic acids. Principal component analysis indicated different correlations between long-chain and short-chain PFAS. Strong positive correlations were found within three groups of perfluoroalkyl carboxylic acids. PFAS near the fire station were likely directly emitted from a point source, while PFAS near other sites had multiple input pathways.

The results suggest that routine application of an acid extraction step in PFAS-impacted soils does not provide advantages. Suspect screening analysis of post-TOP samples identified eight classes of PFAS, some of which may have persistence in the environment and require more routine monitoring.

Performance of in-service granular activated carbon for perfluoroalkyl substances removal under changing water quality conditions

Ruya Chen et al.

Summary: The study found that GAC can adsorb longer-chain PFASs, but pre-chlorination may lead to competition between lower molecular weight NOM and PFASs for adsorption sites, reducing GAC's efficiency in removing PFASs. Additionally, under emergency contamination, PFASs with stronger hydrophobicity may replace those with weaker hydrophobicity.

Presumptive Contamination: A New Approach to PFAS Contamination Based on Likely Sources

Summary: Despite increased research and regulatory attention, data on the scale, scope, and severity of PFAS releases and contamination in the United States are incomplete. This paper argues that in the absence of high-quality testing data, PFAS contamination can be presumed around certain types of facilities. By integrating nationwide data sets, 57,412 sites of presumptive PFAS contamination are identified, including industrial facilities, wastewater treatment plants, military sites, and airports.

Organic Fluorine as an Indicator of Per-and Polyfluoroalkyl Substances in Dust from Buildings with Healthier versus Conventional Materials

Anna S. Young et al.

Summary: This study aimed to determine whether buildings with healthier materials had lower PFAS levels. The study found that rooms with healthier materials had significantly lower PFAS contamination in dust. The measurement of extractable organic fluorine (EOF) proved to be a useful proxy for PFAS levels, but there were likely unidentified PFAS present. Therefore, further expansion of non-PFAS solutions in building materials is needed.

Summary: This study evaluated the removal of three perfluorinated carboxylic acids in ultrapure and river water using two different anion-exchange resins. A new GC/MS method was also developed for PFCA analysis in water. The results showed that A-500P exhibited higher removal capacity and faster removal in ultrapure water, while A-500P achieved better removal of target PFCAs in river water. Both resins achieved similarly high overall reductions of dissolved organic carbon.

Boron-doped diamond electrodes degrade short- and long-chain per- and polyfluorinated alkyl substances in real industrial wastewaters

Alec B. Nienhauser et al.

Summary: The electrochemical oxidation with boron-doped diamond electrode was studied for the removal of six legacy perfluoroalkyl substances (PFAS) in semiconductor fabrication wastewaters. The degradation kinetics decreased with decreasing carbon length in single-solute systems. The presence of PFAS in the solution affected the potential affinity for PFAS on the electrode surface. The wettabiltiy of the electrode surface increased with longer chain length and decreased with increasing PFAS concentration. PFASs with a sulfonated head group degraded faster than their carboxylic counterparts. The presence of surfactants in the wastewater reduced the degradation efficiency. However, multi-solute solutions had higher degradation rates compared to single-solute PFAS systems. Real wastewater containing PFASs could be efficiently treated using electrochemical oxidation.

PFAS Exposure Pathways for Humans and Wildlife: A Synthesis of Current Knowledge and Key Gaps in Understanding

Amila O. De Silva et al.

Summary: The understanding of human and wildlife exposures to PFAS has mainly focused on a few traditional substances, but there is a need for assessment of a wider range of new PFAS. Diet is a major pathway of human exposure to some PFAS, but there is significant variability across populations and compounds. Total fluorine data and information on unidentified organofluorine are essential, and water has been identified as a major exposure source in contaminated communities. As water sources are remediated, other sources of exposure such as dust, personal care products, and indoor environments may become more significant.
