INTEGRATING TOTAL OXIDIZABLE PRECURSOR ASSAY DATA TO EVALUATE FATE AND TRANSPORT OF PFASS
Casson, R. and S.-Y.D. Chiang.
Remediation Journal 28(2):71-87(2018)

Current commercial laboratory methodologies primarily quantify between 14 and 31 per- and polyfluoroalkyl substances. As an alternative, a total oxidizable precursor assay (TOPA) was developed to quantify measurable concentrations of perfluoroalkyl carboxylates (PFCAs) and perfluoroalkyl sulfonates (PFSAs) after aggressive oxidation to convert perfluoroalkyl acid (PFAA) precursors abiotically into PFCAs. This paper discusses the potential application of this approach to characterize PFAS contamination. This paper is Open Access at https://onlinelibrary.wiley.com/doi/full/10.1002/rem.21551.
