The challenges posed by the widespread contamination of soils and groundwater by poly- and perfluoroalkyl substances (PFASs) are immense. Despite growing concerns about human exposure to perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), other PFASs, particularly those derived from aqueous film-forming foams (AFFFs) have garnered little attention.

Recent work using high-resolution mass spectrometry (HRMS) has revealed that there are dozens, if not hundreds, of additional PFASs that may be associated with AFFF-impacted sites. Importantly, many of these newly discovered PFASs have diverse chemical structures, including anionic, cationic, and zwitterionic moieties.

In this webinar, our approach to using HRMS to address the complexity of the PFASs will be presented and discussed. The presentation will cover how HRMS is currently being applied to examining PFASs in environmental samples. Academic, government, and industry scientists analysing PFASs in environmental samples are encouraged to attend.  

By attending this webinar you will learn about...

  • the sorts of PFASs found at AFFF-impacted sites
  • the tools available for the analysis of PFASs by LC-HRMS
