TY - CONF A1 - Vogel, Christian T1 - Per- and polyfluoroalkyl substances (PFAS) in sewage sludge and wastewater-based fertilizers and future PFAS remediation N2 - Per- and polyfluoroalkyl substances (PFAS) are a group of anionic, cationic and zwitterionic synthetic products, in which the hydrogen atoms on the carbon skeleton of at least one carbon atom have been completely replaced by fluorine atoms and which include more than 4730 compounds, depending on the definition. As a result of continuous and prolific use, mainly in aviation firefighting foams, thousands of industrial and military installations have been found to contain contaminated soil, groundwater and surface water. As a result of the perpetual use of PFAS containing products, effluents and sewage sludge from wastewater treatment plants (WWTPs) have been observed to be an important pathway for PFAS into the environment. In Germany, phosphorus and other nutrients from sewage sludge and wastewater should be recycled in WWTPs of cities with a large population. However, it is not clear if PFAS contamination from wastewater and sewage sludge end up in novel wastewater-based fertilizers. Normally, PFAS are analyzed using PFAS protocols typically with liquid chromatography tandem mass spectrometry (LC-MS/MS) quantification. To get a better overview of the amount of “total PFAS,” we applied sum parameter methods based on combustion ion chromatography (CIC) to screen the PFAS contaminations in various sewage sludge and wastewater-based fertilizers. Furthermore, current decontamination strategies of PFAS-burdened soils mainly consist of adsorption methods using adsorbents for fixation of PFAS in the ground. A second option is the utilization of a “pump and treat” process, cycling polluted soils through a washing plant leading to the concentration of the pollutants in the fine fraction. Only a subsequent, high-energy consuming pyrolysis process guarantees the total destruction of all fluorinated organic contaminants. Both approaches are cost-intensive and not intended for the direct decomposition of all PFAS contaminants. Hence, there is a great demand for innovative developments and chemical treatment technologies, dealing with new strategies of tackling the PFAS problem.

Infolge der ständigen Verwendung, vor allem in Feuerlöschschäumen für die Luftfahrt, wurden in Tausenden von Industrie- und Militäranlagen kontaminierte Böden und Grundwasservorkommen gefunden. Aufgrund der ständigen Verwendung von fluorierten Konsumgütern haben sich jedoch auch Abwässer und Klärschlamm aus Kläranlagen als Quelle für die Kontamination der aquatischen Umwelt mit PFAS erwiesen. Infolge der strengeren Vorschriften und Beschränkungen, die in den letzten Jahren für die Verwendung langkettiger (≥C8) PFAS erlassen wurden, findet in der chemischen Industrie eine deutliche Verlagerung hin zur Herstellung kurz- (C4-C7) und ultrakurzkettiger (C1-C3) Alternativen statt. Mit der Novellierung der Klärschlammverordnung im Jahr 2017 hat der deutsche Gesetzgeber die Ausbringung von Klärschlamm auf landwirtschaftlichen Flächen verboten, und bis 2029/2032 wird die Ausbringung von Klärschlamm in der Landwirtschaft vollständig verboten sein. Während die Belastung der Umwelt mit organischen Schadstoffen wie PFAS, Pestiziden und Arzneimitteln nicht mehr erwünscht ist, muss Phosphor (P) aus Klärschlamm weiterhin zur Herstellung hochwertiger P-Dünger für eine Kreislaufwirtschaft genutzt werden. Derzeit können pflanzenverfügbare P-Düngemittel aus Klärschlamm/Abwasser mit verschiedenen Behandlungsmethoden hergestellt werden, darunter Fällung, Auslaugung und thermische Behandlung. Der Verbleib von PFAS bei der Auslaugung, Ausfällung und Behandlung von Klärschlamm und Abwasser ist jedoch noch weitgehend unbekannt.

The standard method to quantify PFCAs in water samples is liquid chromatography or, for additional quantification of ultrashort-chain PFCAs (carbon chain length of two or three carbon atoms) too, hydrophilic interaction liquid chromatography, in each case coupled with mass spectrometry. However, there are a lot of laboratories using MS coupled to headspace gas chromatography systems (HS-GC-MS), usually to quantify a wide range of volatile organic compounds. While PFCAs themselves are difficult to measure with HS-GC-MS in water samples, this challenge can be solved by derivatizing the acids to more volatile compounds, like esters. This approach could enable laboratories using HS-GC-MS to analyse and monitor PFCAs in environmental water samples. By following this idea, we successfully developed a HS-GC-MS method to quantify PFCAs in ultrapure water. Trifluoric acid (TFA), perfluoropropionic acid (PFPrA), perfluorobutanoic acid (PFBA) and perfluorooctanoic acid (PFOS) served as exemplary analytes of PFCAs, which were derivatized with methanol and concentrated sulfuric acid to form methyl esters. The method was optimized by varying different preparation and measurement parameters, leading to limits of detection and quantification in the two-digit ppt-range for all four analytes. The method was than tested on various real water samples, including tap and bottled water, groundwater, landfill leachate, treated wastewater and impinger water from a sewage sludge incineration experiment. Furthermore, snow samples from a ski slope were analysed too. TFA was the most frequently detected PFAA, with concentrations in the ppt and low ppb range. The detection and quantification of the remaining three PFCAs vary with the sample types and sampling location.Our results show that HS-GC-MS is suitable, and enables laboratories with this technique, to quantify PFCAs water samples.

Given previous experience of dioxin formation during halogenated waste incineration, concerns about the emission of products of incomplete destruction (PIDs) from PFAS incineration exist. The overarching objective of this project is to track the fate of fluorine during full-scale hazardous waste incineration in order to demonstrate the readiness, viability, and level of safety for thermal PFAS destruction in various waste streams. The specific objectives of this project are (1) to enhance our understanding of key variables and conditions on PFAS incineration performance, (2) to identify major PIDs under insufficient treatment conditions, (3) to explore the catalytic role of fly ash and other process-relevant surfaces in thermal PFAS decomposition, and (4) to determine the potential formation of polyfluorinated dibenzodioxins and dibenzofurans.

Due to their high chemical stability and resistance to degradation by heat or acids, PFAS were used in a variety of consumer products. The continuous use of PFAS in household products and the discharge of PFAS from industrial plants into the sewer system resulted in the contamination of effluents and sewage sludge from wastewater treatment plants (WWTPs) (Roesch et al. 2022). Since sewage sludge is often used as fertilizer, its application on agricultural soils has been observed as a significant entry path for PFAS into the environment, specifically in our food chain. In Germany the sewage sludge/biosolid application on agricultural land was banned with the amendment of the German Sewage Sludge Ordinance and by 2029 sewage sludge application will be totally prohibited. However, phosphorus (P) from sewage sludge should still be recycled in WWTPs of cities with a population larger than 50,000 residents. To produce high-quality P-fertilizers for a circular economy, PFAS and other pollutants (e.g. pesticides and pharmaceuticals) must be separated from sewage sludge. Due to the strong diversity of industrial PFAS usage it is not clear if a safe application of novel recycled P-fertilizers from WWTPs can be guaranteed. Therefore, we analyzed various sewage sludges and wastewater-based fertilizers. Sewage sludge (SL) samples from various WWTPs in Germany and Switzerland, six sewage sludge ashes (SSA) from Germany, six thermally treated SL and SSA samples with different additives (temperatures: 700-1050 °C), two pyrolyzed SL samples (temperature: 400 °C) and two struvite samples from Germany and Canada were analyzed. The goal was to quantify PFAS in sewage sludges and wastewater-based P-fertilizers with the sum parameter extractable organic fluorine (EOF) by combustion ion chromatography (CIC). The results were compared with data from classical LC-MS/MS target analysis as well as selected samples by HR-MS suspect screening. The EOF values of the SLs mainly range between 154 and 538 µg/kg except for one SL which showed an elevated EOF value of 7209 µg/kg due to high organofluorine contamination. For the SSA samples the EOF values were lower and values between LOQ (approx. 60 µg/kg) and 121 µg/kg could be detected. For the pyrolyzed SLs no EOF values above the LOQ were detected. Moreover, the two wastewater-based struvite fertilizers contain 96 and 112 µg/kg EOF, respectively. In contrast to the EOF values, the sum of PFAS target values were relatively low for all SLs. Additional applied PFAS HR-MS suspect screening aimed to tentatively identify PFAS that could contribute to the hitherto unknown part of the EOF value. The majority of the detected fluorinated compounds are legacy PFAS such as short- and long-chain perfluorocarboxylic acids (PFCA), perfluorosulfonic acids (PFSA), polyfluoroalkyl phosphate esters (PAPs) and perfluorophosphonic acids (PFPA). Moreover, fluorinated pesticides, pharmaceutical as well as aromatic compounds were also identified, which are all included in the EOF parameter. Our research revealed that the current PFAS limit of 100 µg/kg for the sum of PFOS + PFOA in the German Fertilizer Ordinance is no longer up to date. Since the number of known PFAS already exceeds 10,000, the ordinance limit should be updated accordingly. Recent regulations and restrictions on using long-chain PFAS (≥C8) have resulted in a significant shift in the industry towards (ultra-)short-chain alternatives, and other, partly unknown, emerging PFAS. Ultimately, also fluorinated pesticides and pharmaceuticals, which end up as ultrashort PFAS in the WWTPs, have to be considered as possible pollutants in fertilizers from wastewater, too.

The continuous use of PFAS in household products and the discharge of PFAS from industrial plants into the sewer system have been resulted in contaminated effluents and sewage sludge from wastewater treatment plants (WWTPs) which became an important pathway for PFAS into the environment.

Normally, PFAS are analyzed using PFAS protocols typically with time-consuming extraction steps and LC-MS/MS target quantification. However, for screening of PFAS contaminations in wastewater-based fertilizers also the DGT technique can be used for the PFAS extraction. Afterwards, combustion ion chromatography (CIC) can be applied to analyze the “total” amount of PFAS on the DGT binding layer. The DGT method was less sensitive and only comparable to the extractable organic fluorine (EOF) method values of the fertilizers in samples with >150 µg/kg, because of different diffusion properties for various PFAS, but also kinetic exchange limitations. However, the DGT approach has the advantage that almost no sample preparation is necessary. Moreover, the PFAS adsorption on the DGT binding layer was investigated via surface sensitive spectroscopical methods, such as Fourier-transform infrared (FT-IR) and fluorine K-edge X-ray absorption near-edge structure (XANES) spectroscopy.

However, the fate of legacy and emerging PFAS compounds during sewage sludge incineration or pyrolysis is for the most parts still unknown. In particular, PFAS analysis in exhaust air from industrial facilities has not yet been standardized in Germany, which means that no comparable results are available for possible regulation.

N2 - Phosphorus (P) fertilizers from secondary resources became increasingly important in the last years. However, these novel P-fertilizers can also contain toxic pollutants. Chromium in its hexavalent state (Cr(VI)) is regulated with low limit values for agricultural products due to its high toxicity, but the determination of Cr(VI) in these novel fertilizer matrices can be hampered by redox processes that lead to false results. Thus, we applied the passive sampler technique Diffusive Gradients in Thin-films (DGT) for the determination of Cr(VI) in fertilizers and compared the results with the standard wet chemical extraction method (German norm DIN EN 15192) and Cr K-edge X-ray absorption near-edge structure (XANES) spectroscopy. We determined an overall good correlation between the wet chemical extraction and the DGT method. DGT was very sensitive and in most cases selective for the analysis of Cr(VI) in P-fertilizers. However, hardly soluble Cr(VI) compounds cannot be detected with the DGT method since only mobile Cr(VI) is analyzed. Furthermore, Cr K-edge XANES spectroscopy showed that the DGT binding layer also adsorbs small amounts of mobile Cr(III) compounds which leads to overestimated Cr(VI) values. The results of certain types of P-fertilizers containing mobile Cr(III) or partly immobile Cr(VI), showed that optimization of the DGT method is required to avoid over- or underestimation of Cr(VI).

The project involves developing advanced analytical tools, including real-time infrared spectroscopy, and conducting trial burns under varied conditions. Conditions that influence incineration performance are identified, analyzing for products of incomplete destruction (PIDs), exploring the role of fly ash and surfaces in PFAS breakdown, and evaluating the potential formation of polyfluorinated dioxins and furans.
