Enhancing both the Intensities and Resolution of19F NMR Spectra of PFAS through Band-Selective Homonuclear Decoupling Markus Rotzinger, Viktoria Müller, Armin Macher, Jörg Feldmann, Klaus Zangger Analytical Chemistry, 2026 High Resolution Image Download MS PowerPoint Slide A method for acquiring fluorine nuclear magnetic resonance ( 19 F NMR) spectra of perfluoroalkyl and polyfluoroalkyl substances (PFASs) is described. The experiment uses band-selective homonuclear decoupling of the CF 3 spectral region (around −82.4 ppm) and results in spectra showing both enhanced resolution and enhanced signal intensities for perfluorinated compounds. PFAS mixtures, which show highly overlapped multiplet signals in conventional 19 F NMR spectra, are reduced to individual separated singlets, enabling not only their identification but also quantification, which does not depend on the chemical nature of each compound.
PFAS contamination and fluorine mass balance in sediments of the Upper Ganges River and Ganges Canal Viktoria Müller, Zofia Kowalewska, Andreas Roth, Abhyanand Singh Maurya, Jörg Feldmann, et al. Environment International, 2026 Although concerns about per- and polyfluoroalkyl substances (PFAS) are growing in Europe and in The United States, there are limited of studies on the occurrence of PFAS and fluorinated organic compounds in India. This study presents a comprehensive investigation of PFAS contamination in sediments from the upper Ganges River, India. More than 40 PFAS were targeted using liquid chromatography tandem mass spectrometry (LC-MS/MS), along with total oxidisable precursor analysis (dTOPA), non-targeted analysis using LC-HRMS/MS and extractable organic fluorine (EOF) analyses to evaluate the levels of PFAS burden. This is the first study doing fluorine mass balance analysis on sediments from the Ganges. Sixteen PFAS were detected in at least one sample, with short- and ultrashort-chain PFAS dominating the profile. TFA and PFPrA were found in all samples, while PFOA, 4:2 FTS, and PFMPA appeared in more than 50%. Concentrations of individual PFAS ranged from 0.02 to 5.3 ng g −1 , while ∑ Target PFAS concentrations ranged from 3.4 to 8.6 ng g −1 . dTOPA analysis revealed substantial precursor presence, with ∑dTOPATarget PFAS values ranging from 3.1 to 311 ng g −1 . EOF levels increased by a factor of 5 in the investigated stretch from 180 to 780 ng F g −1 with non-oxidised target PFAS accounting for only up to 1.3% of EOF, indicating a large fluorine gap. Oxidized samples showed improved identification rates, with precursor-derived PFAS contributing up to 26% of EOF at some sites. The findings highlight the need for expanded monitoring strategies and regulatory frameworks addressing PFAS in India, especially given the lack of current regulation and wastewater treatment infrastructure.
PFAS in the buzz: Seasonal biomonitoring with honey bees (Apis mellifera) and bee-collected pollen Viktoria Müller, Jörg Feldmann, Eileen Prieler, Robert Brodschneider Environmental Pollution, 2025 Per- and polyfluoroalkyl substances (PFAS) are emerging environmental contaminants with known persistence, bioaccumulation potential, and ecotoxicological relevance. This study investigates the occurrence, distribution, and potential exposure pathways of PFAS in honey bee-related matrices (pollen, forager bees, hive bees). Samples were collected from six sites over a full season representing diverse land uses (urban, semi-urban, rural, and agricultural). A total of nine different PFAS were detected across 90 samples, with short-chain compounds such as 4:2 FTS, PFPS, and PFBS predominating. Hive bees exhibited the highest average sum of target PFAS concentration (5.29 ng g ꟷ1 ), followed by forager bees (1.93 ng g ꟷ1 ), and pollen (1.10 ng g ꟷ1 ). Differences in PFAS occurrence among sample types, especially PFPS between forager and hive bees, suggested various exposure routes, including pollen ingestion, atmospheric deposition, and contact with contaminated surfaces. Temporal and spatial differences were notable. Site-specific PFAS patterns highlighted potential contamination sources, such as fluorinated pesticide use, while seasonal variation suggested influence from plant phenology and rainfall. Principal component analysis (PCA) confirmed the dominance of shared PFAS profiles, with some outlier samples exhibiting unique signatures. PFPS and PFBS were positively correlated with total fluorine (TF) concentrations, while 4:2 FTS showed a strong site-specific association. Extractable organic fluorine (EOF) remained below detection limits (800 ng F g ꟷ1 ), but TF was present in all samples above LOD (500 ng F g ꟷ1 ) confirming the presence of additional unidentified fluorinated compounds. Although EOF and PFAS concentrations varied, we showed that forager bees can introduce PFAS in the hive, either on their bodies, or through contaminated resources such as nectar or pollen. These findings demonstrate the suitability of honey bees as bioindicators for PFAS contamination but emphasise the need for harmonized sampling to fully assess PFAS exposure dynamics.
Comparison study of PFAS in farmed and wild shrimps from Brazil. Are wild shrimps less contaminated than farmed shrimps? Viktoria Müller, Fernanda P. Balbinot, Marc Preihs, Marcia F. Mesko, Francisco L.F. da Silva, et al. Journal of Food Composition and Analysis, 2025 Production and consumption of seafood (such as shrimp) are in increasing demand in Brazil, giving rise to open ocean fisheries in addition to aquaculture. Per – and polyfluoroalkyl substances (PFAS) are a group of persistent organic pollutants, widely present in the environment, which have adverse effects on human health. Due to the abundant sources of PFAS, shrimps from open ocean fisheries and aquaculture might show different levels and species of PFAS, however, little is available on this topic from the Southern Hemisphere. In this study, farmed and wild shrimps were investigated for more than 30 different legacy and precursor PFAS. We also evaluated extractable organofluorine (EOF), inorganic fluoride, and total fluorine to use a mass balance approach to verify the agreement of the sum of the species with the total fluorine content. Farmed shrimps overall (whole, carapace, tissue) contained a similar concentration of target sum of PFAS when compared to the wild one (2.2 ± 2.4 ng g −1 and 2.7 ± 1.6 ng g −1 respectively, p > 0.05). PFPS and PFdDA were observed only in wild shrimps, while PFNS and PFHpA were observed only in the farmed ones. PFOA, PFDA, PFuDA, PFtrDA and MetFOSAA were found in both types of shrimps. Target PFAS contributed a maximum of 3.9 % of EOF content. Wild shrimps contained almost double the EOF concentration than farmed shrimps (424 ± 104 ng F g −1 and 231 ± 63 ng F g −1 ). PFAS intake through shrimp consumption was calculated to be below the tolerable weekly intake (4.4 ng kg −1 bodyweight, defined by EFSA) using the sum of targeted PFAS, while using EOF it was orders of magnitude higher (between 150 and 1500 ng kg −1 bodyweight), implying potential risk from the exposure to organofluorines. • Farmed and wild shrimps contained similar concentrations of sum of target PFAS. • Wild shrimps contained significantly higher extractable organic fluorine and total fluorine than farmed shrimps. • Target analysis accounted for a max of 3.9 % of extractable organofluorine. • Extractable organofluorine accounted for max 35.6 % of total fluorine. • Organofluorine intake could be orders of magnitude higher than the human tolerable weekly intake.
Comparison of CIC and HR GFMAS for the measurements of extractable organofluorines (EOF) in different biological tissues of pilot whales Amnah Al Zbedy, Rudolf Aro, Abdullah Akhdhar, Viktoria Müller, Rainer Ebel, et al. Analytica Chimica Acta, 2025 BACKGROUND: In most water and biological samples, the sum of target or even non-target PFAS makes up only a small fraction of the extractable organofluorine (EOF). The methods used for EOF analysis in the methanol are combustion ion chromatography (CIC) and recently high-resolution graphite furnace molecular absorption spectrometry (HR GFMAS). Water samples show a bias towards higher concentrations measured with HR GFMAS than that of CIC. Whether the bias depends on the type of PFAS or on the sample matrix has not been known. Here we study the PFAS compound and the matrix effect using HR GFMAS and compare these with the CIC results. RESULTS: Calibration of the HR GFMAS with fluoride exhibit significant higher response than using PFOA indicating a compound specific effect. PFOA calibration gave in the average quantitative recoveries for different type of PFAS in methanol, although neutral PFAS (FTOH) show lower recoveries than PFCA using HR GFMAS. Spiked PFOA in brain and liver tissue samples resulted in quantitative recoveries (101 %) using HR GFMAS. 44 liver, kidney, blubber and brain samples from stranded pilot whales were analysed by HR GFMAS and compared to the EOF concentrations analysed by CIC. All EOF results were above the LOD of both methods; 27 and 916 ng/g (CIC) and between 77 and 3130 ng/g (HR GFMAS). In general HR GFMAS gave significantly higher results for all tissues than CIC (p > 0.05). Correlations between the EOF of all tissues showed a tissue dependant behaviour. SIGNIFICANCE: Since PFOA recovery was in brain and liver quantitative, the results indicate that PFAS type influence the performance using HR GFMAS. Overall, we found the concentrations in the different tissues to be comparable with the two methods within one order of magnitude. This highlights the fact that more work is needed to identify the matrix effects and fluorine species dependant responses of both methods.
A multi-platform approach for the comprehensive analysis of per- and polyfluoroalkyl substances (PFAS) and fluorine mass balance in commercial ski wax products Raquel Gonzalez de Vega, Merle Plassmann, David Clases, Klaus Zangger, Viktoria Müller, et al. Analytica Chimica Acta, 2024 The unique properties of per- and polyfluoroalkyl substances (PFAS) have led to their extensive use in consumer products, including ski wax. Based on the risks associated with PFAS, and to align with PFAS regulations, the international ski federation (FIS) implemented a ban on products containing “C8 fluorocarbons/perfluorooctanoate (PFOA)” at all FIS events from the 2021/2022 season, leading manufactures to shift their formulation towards short-chain PFAS chemistries. To date, most studies characterising PFAS in ski waxes have measured a suite of individual substances using targeted analytical approaches. However, the fraction of total fluorine in the wax accounted for by these substances remains unclear. In this study, we sought to address this question by applying a multi-platform, fluorine mass balance approach to a total of 10 commercially available ski wax products. Analysis of total fluorine (TF) by combustion ion chromatography (CIC) revealed concentrations of 1040 - 51700 μg F g-1 for the different fluorinated waxes. In comparison, extractable organic fluorine (EOF) determined in methanol extracts by CIC (and later confirmed by inductively-coupled plasma-mass spectrometry and 19F- nuclear magnetic resonance spectroscopy) ranged from 92 to 3160 μg g-1, accounting for only 3 to 8.8% of total fluorine (TF). Further characterisation of extracts by cyclic ion mobility-mass spectrometry (IMS) revealed 15 individual PFAS with perfluoroalkyl carboxylic acid concentrations up to 33 μg F g-1, and 3 products exceeding the regulatory limit for PFOA (0.025 μg g-1) by a factor of up to 100. The sum of all PFAS accounted for only 0.01 to 1.0 % of EOF, implying a high percentage of unidentified PFAS, thus, pyrolysis gas chromatography-mass spectrometry was used to provide evidence of the nature of the non-extractable fluorine present in the ski wax products.
Fluorine mass balance analysis in wild boar organs from the Bohemian Forest National Park Till Schröder, Viktoria Müller, Marc Preihs, Jan Borovička, Raquel Gonzalez de Vega, et al. Science of the Total Environment, 2024 Wild boars have been reported as bioindicators for per- and polyfluoroalkyl substances (PFAS) in a variety of studies. However, data about PFAS levels in wild boars from sites with limited industrial and general human activity is scarce. In this study, wild boar (Sus scrofa) organs from the Bohemian Forest National Park (Czech Republic) were used as bioindicators for PFAS pollution. In this work, 29 livers and 24 kidneys from 30 wild boars (0.5–5 years) were investigated using a fluorine mass balance approach. For this, the samples were measured using high performance liquid chromatography with electrospray ionisation tandem mass spectrometry (HPLC-ESI-MS/MS), targeting 30 PFAS, including legacy and replacement PFAS, direct total oxidisable precursor assay (dTOPA) and combustion ion chromatography (CIC). Perfluorocarboxylic acids (PFCAs) from C7 to C14 and perfluorooctanesulfonic acid (PFOS) were detected in >50 % of samples. In the livers, PFCAs dominated the profile with median concentrations of 230 μg/kg for perfluorononanoic acid (PFNA) and 75 μg/kg perfluorooctanoic acid (PFOA). PFOA and PFNA concentrations in the livers were one order of magnitude higher than in livers from wild boars caught in rural NE Germany considered as background concentration. PFOS in liver contributed only 30 % to the Σc(PFASTarget) with a median concentration of 170 μg/kg. Kidneys and livers contain an average of 2460 μg F/kg and 6800 μg F/kg extractable organic fluorine (EOF) respectively. Σc(PFASTarget) add up to a maximum of 10 % of the extractable organic fluorine. After oxidisation of the samples, PFOA, PFNA and Σc(PFASdTOPA) increased in livers, but could not explain the EOF. The elevated concentration of PFOA and PFNA may indicate differences in biomagnification for different habitats or an unidentified PFAS source in proximity to the national park.
Analysis of per- and polyfluoroalkyl substances (PFAS) in raw materials intended for the production of paper-based food contact materials–evaluating LC-MS/MS versus total fluorine and extractable organic fluorine Milica Jovanović, Viktoria Müller, Jörg Feldmann, Erich Leitner Food Additives and Contaminants Part A, 2024 Per-and polyfluoroalkyl substances (PFAS) analysis has become crucial due to their presence in the environment, their persistence and potential health risks.These compounds are commonly used in food contact materials (FCM) as a coating to provide water and grease-repellent properties.One of the pathways for PFAS to enter the human body is either through direct consumption of contaminated food or indirectly through migration from FCM into food.The purpose of this study was to investigate where the initial contamination of paper FCM occurs.We analysed paper material consisting of fresh fibre and secondary materials, intended to produce food packaging for the presence of PFAS.The samples were extracted and analysed for 23 different PFAS substances using the targeted approach with LC tandem mass spectrometry (LC-MS/MS).This analytical technique detects specific, easily ionisable PFAS with high sensitivity.However, one drawback of this approach is that it allows the identification of less than 1% of the PFAS known today.For this reason, we used combustion ion chromatography (CIC) to determine the content of extractable organic fluorine compounds (EOF) and compare it to the total fluorine content.The targeted analysis using LC-MS/MS measured an average sum concentration of PFAS of 0.17 ng g -1 sample.Our research shows that the primary PFAS contamination happens during the recycling process since all of the samples in which the targeted PFAS were measured belonged to the secondary material.The most frequently detected analytes were PFOA and PFOS, detected in 90% and 62% of the samples, respectively, followed by PFBS (in 29% of the samples).CIC showed that measured PFAS via LC-MS/MS amount to an average of 2.7 10 -4 % of total fluorine content, whereas the EOF was under the LOD in all of the measured samples.This result highlights the complexity of the accurate determination of PFAS compounds, displaying what kind of information the chosen methods provide.
