Asadi Zeidabadi, F., et al. (2024). "Structural dependence of PFAS oxidation in a boron doped diamond-electrochemical system." Environmental Research 246 C7 - 118103.

Driven by long-term persistence and adverse health impacts of legacy perfluorooctanoic acid (PFOA), production has shifted towards shorter chain analogs (C4, perfluorobutanoic acid (PFBA)) or fluorinated alternatives such as hexafluoropropylene oxide dimer acid (HFPO-DA, known as GenX) and 6:2 fluorotelomer carboxylic acid (6:2 FTCA). Yet, a thorough understanding of treatment processes for these alternatives is limited. Herein, we conducted a comprehensive study using an electrochemical approach with a boron doped diamond anode in Na2SO4 electrolyte for the remediation of PFOA common alternatives, i.e., PFBA, GenX, and 6:2 FTCA. ? 2024 The Authors

Bui, T. H., et al. (2024). "PFAS remediation in soil: An evaluation of carbon-based materials for contaminant sequestration." Environ Pollut 344: 123335.

The presence of per- and poly-fluoroalkyl substances (PFAS) in soils is a global concern as these emerging contaminants are highly resistant to degradation and cause adverse effects on human and environmental health at very low concentrations. Sequestering PFAS in soils using carbon-based materials is a low-cost and effective strategy to minimize pollutant bioavailability and exposure, and may offer potential long-term remediation of PFAS in the environment. This paper provides a comprehensive evaluation of current insights on sequestration of PFAS in soil using carbon-based sorbents.

Crawford, K. A. and N. Hartmann (2024). "Respiratory Exposure to Highly Fluorinated Chemicals via Application of Ski Wax and Related Health Effects." Curr Environ Health Rep.

PURPOSE: Waxes containing per- and polyfluoroalkyl substances (PFAS) are applied to the base of skis and snowboards ("skis") to reduce friction with the snow surface and improve glide. PFAS exposure can adversely impact cardiometabolic, thyroid, liver, kidney, reproductive, and immune health and are associated with increased risk of certain cancers. In the present review, we summarize the state of the science on PFAS exposure from fluorinated ski wax use, including acute respiratory health effects and PFAS concentrations in biological and environmental media collected from ski waxing settings.

Dai, C., et al. (2024). "Distribution of per- and polyfluoroalkyl substances in blood, serum, and urine of patients with liver cancer and associations with liver function biomarkers." Journal of Environmental Sciences (China) 139: 418-427.

Studies have shown that per- and polyfluoroalkyl substances (PFASs) may be hepatotoxic in animals or humans. However, data on clinical epidemiology are very limited. In this study, 21 PFASs were determined in patients with liver diseases, with the highest median concentrations detected in the serum sample (26.7 ng/mL), followed by blood (10.7 ng/mL) and urine (5.02 ng/mL). ? 2023

Dey, D., et al. (2024). "Progress and perspectives on carbon-based materials for adsorptive removal and photocatalytic degradation of perfluoroalkyl and polyfluoroalkyl substances (PFAS)." Chemosphere 351: 141164.

Per- and polyfluoroalkyl substances (PFAS) (also known as 'forever chemicals') have emerged as trace pollutants of global concern, attributing to their persistent and bio-accumulative nature, pervasive distribution, and adverse public health and environmental impacts. The unregulated discharge of PFAS into aquatic environments represents a prominent threat to the wellbeing of humans and marine biota, thereby exhorting unprecedented action to tackle PFAS contamination. Indeed, several noteworthy technologies intending to remove PFAS from environmental compartments have been intensively evaluated in recent years. Amongst them, adsorption and photocatalysis demonstrate remarkable ability to eliminate PFAS from different water matrices.

Hassan, M. T. A., et al. (2024). "Rapid detection of per- and polyfluoroalkyl substances (PFAS) using paper spray-based mass spectrometry." Journal of Hazardous Materials 465 C7 - 133366.

Traditional PFAS analysis by mass spectrometry (MS) is time-consuming, as laborious sample preparation (e.g., extraction and desalting) is necessary. Herein, we report fast detection of PFAS by paper spray (PS)-based MS techniques, which employs a triangular-shaped filter paper for sample loading and ionization (≤ 3 min per sample). In this study, PS-MS was first used for direct PFAS analysis of drinking water, tap water, and wastewater. ? 2024 Elsevier B.V.?

Lennquist, A., et al. (2024). "Facilitating the market transition away from persistent and mobile substances: a report on tools developed by ChemSec in the ZeroPM project: SIN list, Marketplace and the PFAS guide." Environmental Sciences Europe 36(1 C7 - 2).

Persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances have gained significant attention in recent years. The substances do not break down in the environment over appreciable time scale, can travel long distances with water bodies and can cause toxic effects on the environment and human health. Hazard classes for these substances were introduced into the Classification, Labelling and Packaging Regulation in March 2023. A key preventative measure to reduce manufacture, use and emissions of PMT/vPvM substances, is a market transition away from these substances to less harmful alternatives. Companies may be unaware of which of their products contain PMT/vPvM substances. The Horizon Europe research project?ZeroPM: Zero pollution of persistent, mobile substances is seeking to support this market transition by developing and further extending tools including the Substitute It Now (SIN) List, the Marketplace and a PFAS Guide for companies. These tools will be discussed. ? 2024, The Author(s).

Liu, D., et al. (2024). "Association of prenatal exposure to perfluorinated and polyfluoroalkyl substances with childhood neurodevelopment: A systematic review and meta-analysis." Ecotoxicol Environ Saf 271: 115939.

?BACKGROUND: Although previous studies have shown an association between prenatal exposure to perfluorinated and polyfluoroalkyl substances (PFAS) and neurodevelopmental disorders in children, the results have been inconsistent. We summarize studies on the association between prenatal PFAS exposure and neurodevelopment in children in order to better understand the relationship. OBJECTIVE: We conducted a meta-analysis of prenatal PFAS exposure and developmental outcomes associated with intellectual, executive function and behavioral difficulty in children to explore the relationship between prenatal exposure to perfluorinated and polyfluoroalkyl substances (PFAS) and neurodevelopmental disorders in children.

Marchiandi, J., et al. (2024). "Exposure to endocrine disrupting chemicals from beverage packaging materials and risk assessment for consumers." Journal of Hazardous Materials 465 C7 - 133314.

This study investigated the influence of beverage packaging materials on the presence of endocrine disrupting chemicals (EDCs) in plastic, glass, carton, aluminium, and tin canned non-alcoholic beverages. Results showed that 63 EDCs including perfluoroalkyl and polyfluoroalkyl substances (PFAS), bisphenols, parabens, benzophenone-type UV-filters, biocides, nitrophenols, and alkylphenols, were detected in 144/162 screened products. ? 2023 The Authors

Nguyen, D., et al. (2024). "Removal of per- and polyfluoroalkyl substances from wastewater via aerosol capture." Journal of Hazardous Materials 465 C7 - 133460.

The widespread use of per- and polyfluoroalkyl substances (PFAS)-containing products in numerous commercial and industrial applications has resulted in their occurrence in wastewater treatment plants (WWTPs). Herein, proof-of-concept bench-scale experiments were performed to measure the extent to which PFAS could be removed from a WWTP if aerosols generated during aeration were captured. ? 2024 Elsevier B.V.

Ross, T. A., et al. (2024). "Running the gauntlet; flyway-wide patterns of pollutant exposure in blood of migratory shorebirds." Environmental Research 246 C7 - 118123.

Shorebirds (order Charadriiformes) are among the world's most threatened avian taxa. Within the East Asian-Australasian Flyway (EAAF), a major threat to shorebirds' survival may be the gauntlet of pollution along the flyway. Metals, persistent organic pollutants (POPs), and per-/polyfluoroalkyl substances (PFASs) persist in the environment to the detriment of wildlife. In this study, we analysed element and PFAS concentrations in blood from 142 individuals across six species of Arctic-breeding migratory shorebirds with contrasting population trends, to discern species- and site-specific pollution differences, and determine how pollution correlated with population trends of EAAF shorebirds. ? 2024 Elsevier Inc.
