  • Professor Damien Arrigan, from the School of Molecular and Life Sciences at Curtin University, explained PFAS (per- and polyfluorinated alkyl substances) are potentially harmful chemical materials that were used for a long time in various commercial and industrial applications, including in firefighting foams, some non-stick cookware, stain and water resistant coatings on carpet and clothing, and various paper and packaging products.
  • Typically speaking, to find out if a site or body of water is contaminated with PFAS materials, soil or water samples must be taken from a site and then taken to a laboratory for chemical analysis, a process which may take several days.
  • The full research paper, Detection of perfluorooctane sulfonate by ion-transfer stripping voltammetry at an array of microinterfaces between two immiscible electrolyte solutions, was published in the journal Analyst and can be found online here.
