Abstract: Several poly- and perfluorinated alkyl substance (PFAS) have become a global concern due to their persistence, long-range transport, bioaccumulation and adverse effects, and PFOS and PFOA are being included in the Stockholm Convention on persistent organic pollutants, POPs. Recent regulatory decisions have resulted in maximum contaminant levels (MCLs) in drinking water range from 2 ng/L in Denmark to tens of ng/L for several PFAS combined in several states in the US. Recently, the US EPA published an interim health advisory level that deemed PFOA and PFOS safe at below 1 ng/L each, which highlights the analytical challenge of measuring such low concentrations. Passive sampling (a process relying on diffusion to enrich PFAS in a sorbent of choice) might provide a means of obtaining representative concentrations of PFAS in surface and groundwater, and of selected volatile precursor concentrations in indoor and ambient air. The presentation will discuss novel approaches to the development of passive sampling tools, and their applications.
