“…Per-and poly uoroalkyl substances (PFASs), often termed "forever chemicals," have been recognized as environmental contaminants across various regions due to their persistence, bioaccumulation, and potential adverse impacts on human health and the environment [1,2]. Mass production of PFAS began in the 1950s by US chemical companies, and the use of these substances has grown since the 1970s across diverse applications, including re ghting foams, water-repellent fabrics, fast-food containers, photolithography materials, and ame retardants [3][4][5].…”

This paper presents a screening method for diverse classes of per- and polyfluoroalkyl substances (PFAS) in consumer products using a Pyrolysis Gas Chromatography Mass Spectrometer (Py-GC-MS). During the pyrolysis process, polar functional groups (carboxylic or sulfonic) are thermally dissociated, allowing the non-polar perfluoroalkyl moieties to elute through the GC column. We successfully detected various classes of PFAS, from non-polymeric forms of different chain lengths to polymeric forms, within 30 minutes, achieving detection limits below 1/100 of the typical intentional use concentrations of PFAS in consumer products. Therefore, the screening method can detect even low levels of intentionally added PFAS within a comfortable margin.
