About this collection

The challenges raised by per- and polyfluoroalkyl substances (PFASs) in the environment are unlike those historically faced by environmental scientists and engineers. Their persistence, their mobility, their surface-active behavior, and their common presence in complex mixtures of varying chemical properties make it challenging to detect and analyze PFASs, to model and predict their behavior in the environment, and to treat them in contaminated water systems.

This collection, Guest Edited by Lutz Ahrens (Swedish University of Agricultural Sciences), Jonathan Benskin (Stockholm University, Sweden), Ian Cousins (Stockholm University, Sweden), Michelle Crimi (Clarkson University, USA) and Chris Higgins (Colorado School of Mines, USA), showcases high-impact papers on the theme of PFAS, spanning publications in both ESPI and ESWRT.
