Poly- and perfluorinated alkyl substances (PFAS)

PFAS have been detected on contaminated agricultural soils loaded with compost and fibers from paper industry. Details on PFAS products and their environmental fate are largely unkown. Therefore, we are applying nontarget screening approaches with LC-high-resolution mass spectrometry and Kendrick mass analysis to screen environmental samples for PFAS products and transformation products. We apply electrochemical oxidation and simulated sunlight experiments to characterize PFAS contamination and to investigate the fate of PFAS in the field.
