The prevalence of fluorinated contaminants, particularly per- and polyfluoroalkyl substances (PFAS), in environmental and industrial settings poses significant health and regulatory challenges. Traditional analytical methods for quantifying these compounds often require extensive sample preparation and costly instrumentation. Particle-Induced Gamma-Ray Emission (PIGE) spectroscopy offers a rapid, non-destructive alternative for detecting and quantifying fluorine in complex matrices. This technique leverages high-energy ion beams to excite atomic nuclei, resulting in characteristic gamma-ray emissions that can be used to measure fluorine concentrations with high sensitivity. It provides a reliable means of screening for fluorinated pollutants with minimal sample preparation, making it a valuable tool for environmental monitoring and remediation efforts. In this talk, I will discuss the application of PIGE spectroscopy for the quantification of PFAS in various environmental samples, specifically solid wastes and treated matrices.
