“…Their applications are equally diverse, ranging from chrome plating and hydraulic fluids [35,36] to sectors such as electronics and semiconductors [37]. Additionally, compounds such as perfluorosulfonic acid (PFSA) and perfluorocarboxylic acids (PFCA) are integral in firefighting foams [38,39], highlighting the widespread utility of nonpolymeric PFAS in various commercial and industrial settings. and perfluorocarboxylic acids (PFCA) are integral in firefighting foams [38,39], highlighting the widespread utility of nonpolymeric PFAS in various commercial and industrial settings.…”

Per- and polyfluoroalkyl substances (PFAS), also known as forever chemicals, exhibit exceptional chemical stability and resistance to environmental degradation thanks to their strong C-F bonds and nonpolar nature. However, their widespread use and persistence have a devastating impact on the environment. This review examines the roles of PFAS in tribological applications, specifically in lubricants and lubricating systems. This article focuses on conventional and advanced lubricants, including ionic liquids (ILs) and their use in modern automotive vehicles. The objective of this paper is to provide a comprehensive overview of the adverse impacts of PFAS whilst acknowledging their outstanding performance in surface coatings, composite materials, and as additives in oils and greases. The pathways through which PFAS are introduced into the environment via lubricating systems such as in seals and O-rings are identified, alongside their subsequent dispersion routes and the interfaces across which they interact. Furthermore, we examine the toxicological implications of PFAS exposure on terrestrial and aquatic life forms, including plants, animals, and humans, along with the ecological consequences of bioaccumulation and biomagnification across trophic levels and ecosystems. This article ends with potential remediation strategies for PFAS use, including advanced treatment technologies, biodegradation, recovery and recycling methods, and the search for more environmentally benign alternatives.

“…2 PFAS are used in industrial applications extensively, as a nonstick coating for pans and cookware (polytetrafluoroethylene, commonly known as Teflon), lubricants, surfactants, or firefighting foams. 1,[3][4][5] Released into the environment, PFAS behave as persistent organic contaminants to such an extent that their presence was confirmed in abiotic components such as air, dust, and water [6][7][8] as well as in organisms where accumulation is observed.

“…Recently, the understanding of PFAS was revisited by the Organisation for Economic Co‐operation and Development with the adoption of the following definition: “PFAS are fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom (without any H/Cl/Br/I atom attached to it), i.e. with a few noted exceptions, any chemical with at least a perfluorinated methyl group (–CF 3 ) or perfluorinated methylene group (–CF 2 –) is a PFAS.” 2 PFAS are used in industrial applications extensively, as a nonstick coating for pans and cookware (polytetrafluoroethylene, commonly known as Teflon), lubricants, surfactants, or firefighting foams 1,3–5 . Released into the environment, PFAS behave as persistent organic contaminants to such an extent that their presence was confirmed in abiotic components such as air, dust, and water 6–8 as well as in organisms where accumulation is observed 9–11 .…”

Liquid chromatography–tandem mass spectrometry (LC–MS/MS) is a widespread technology used for the quantitative determination of per‐ and polyfluoroalkyl substances (PFAS) in foodstuff. Specifically, LC–MS/MS offers an attractive performance by combining the sensitivity and selectivity required by the European Union for testing perfluorooctane sulfonic acid, perfluorooctanoic acid, perfluorononanoic acid, and perfluorohexane sulfonic acid with maximum limits of quantification (LOQ) in the sub‐parts‐per‐billion (μg/kg) or the parts‐per‐trillion (ng/kg) domains. In this article, we highlight the important diversity in LOQ definitions applied in LC–MS/MS methods described in the literature that raise concerns about the capability of some of those to generate reliable data requested by the European regulation. Here, we point out the risk of false response or misquantification if the criteria for assessing LOQ suffer from a lack of rigor. We emphasize the need to use PFAS‐free samples spiked with the analyte(s) of interest and the application of identification criteria according to official documents for a sound measurement of the LOQ.

“…These chemicals possess unique structural attributes and function as surfactants that resist heat, oil, stains, grease, and water [ 2 , 3 ]. They are therefore used as fabric protectants, heat resistant non-stick cookware, adhesives, food packaging, electroplating, and aqueous fire-fighting foams [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. As a result, PFAS are found all over the planet, do not break down in the environment, can move through soils and contaminate drinking water sources, and build up (bioaccumulate) in humans and wildlife.…”

Limited availability of fish metabolic pathways for PFAS may lead to risk assessments with inherent uncertainties based only upon the parent chemical or the assumption that the biodegradation or mammalian metabolism map data will serve as an adequate surrogate. A rapid and transparent process, utilizing a recently created database of systematically collected information for fish, mammals, poultry, plant, earthworm, sediment, sludge, bacteria, and fungus using data evaluation tools in the previously described metabolism pathway software system MetaPath, is presented. The fish metabolism maps for 10 PFAS, heptadecafluorooctyl(tridecafluorohexyl)phosphinic acid (C6/C8 PFPiA), bis(perfluorooctyl)phosphinic acid (C8/C8 PFPiA), 2-[(6-chloro-1,1,2,2,3,3,4,4,5,5,6,6-dodecafluorohexyl)oxy]-1,1,2,2-tetrafluoroethanesulfonic acid (6:2 Cl-PFESA), N-Ethylperfluorooctane-1-sulfonamide (Sulfuramid; N-EtFOSA), N-Ethyl Perfluorooctane Sulfonamido Ethanol phosphate diester (SAmPAP), Perfluorooctanesulfonamide (FOSA), 8:2 Fluorotelomer phosphate diester (8:2 diPAP), 8:2 fluorotelomer alcohol (8:2 FTOH), 10:2 fluorotelomer alcohol (10:2 FTOH), and 6:2 fluorotelomer sulfonamide alkylbetaine (6:2 FTAB), were compared across multiple species and systems. The approach demonstrates how comparisons of metabolic maps across species are aided by considering the sample matrix in which metabolites were quantified for each species, differences in analytical methods used to identify metabolites in each study, and the relative amounts of metabolites quantified. Overall, the pathways appear to be well conserved across species and systems. For PFAS lacking a fish metabolism study, a composite map consisting of all available maps would serve as the best basis for metabolite prediction. This emphasizes the importance and utility of collating metabolism into a searchable database such as that created in this effort.
