HRMS-Based Suspect and Nontarget Screening for Comprehensive PFAS Analysis of Soils near a Fluorochemical Site in Flanders Oliver Salangad, Francesca Cappelli, Fabian Simon, Jodie Buytaert, Lieven Bervoets, Thimo Groffen, Adrian Covaci Environmental Science Technology, 2025 High Resolution Image Download MS PowerPoint Slide Targeted analysis of per- and polyfluoroalkyl substances (PFAS) relies on a limited number of reference standards, and consequently, many PFAS remain unidentified, which restricts comprehensive monitoring and risk assessment. Here, we apply high-resolution mass spectrometry (HRMS)-based suspect and nontarget screening (SS/NTS), alongside targeted analysis, to detect and (semi)quantify legacy, emerging, and novel PFAS in soils near a PFAS hotspot in Flanders, Belgium. Targeted analysis quantified 36 PFAS, with perfluorooctanesulfonic acid (PFOS) as the most predominant, alongside precursors such as ethyl perfluorooctane sulfonamido acetic acid (Et-FOSAA) and perfluorooctane sulfonamide (FOSA). On the other hand, SS/NTS identified over 100 PFAS homologues and isomers, including pentafluorosulfide sulfonic acids (SF 5 -PFSAs), perfluorophosphinic acids (PFPiAs), and perfluorophosphoric diesters (PFPDEs). Total PFAS concentrations at the 3M site varied widely, reaching 118.5 μg/g, among the highest reported globally. These findings highlight the complexity of PFAS contamination in the study area and the need for site-specific analyses to support monitoring, source tracking, regulation, and risk assessment.
