Concentration profiles of per- and polyfluoroalkyl substances in major sources to the environment

ByPFAS Primer Team

A review of published literature was conducted to present the concentrations and composition profiles of per- and polyfluoroalkyl substances (PFAS) from significant sources to the environment. The characteristic compounds and concentrations are summarized as found from direct sources such as manufacturing facilities, aqueous film-forming foam (AFFF) applications, metal coating operations, and textile and paper coating…

Membrane-based technologies for per- and poly-fluoroalkyl substances (PFASs) removal from water: Removal mechanisms, applications, challenges and perspectives

ByPFAS Primer Team

The study critically reviews and analyzes the current state-of-the-art of membrane-based techniques for PFASs removal, including direct membrane filtrations, adsorption-based membranes, and hybrid membrane processes. September 21, 2021 | Environment International

Removal of per- and poly-fluoroalkyl substances (PFASs) by wetlands: Prospects on plants, microbes and the interplay

ByPFAS Primer Team

This review focuses on how plants, microbe, substrate can influence PFASs removal in wetlands under natural and controlled conditions. August 25, 2021 | Science of The Total Environment

Perfluoroalkyl substances (PFAS) adsorption in drinking water by granular activated carbon: Influence of activated carbon and PFAS characteristics

ByPFAS Primer Team

Adsorption onto activated carbon (AC) has been identified as an effective technique to remove PFAS. Adsorption isotherms and breakthrough curves, determined by rapid small-scale column tests (RSSCTs), were studied for eight PFAS and four granular ACs, characterized by different origins, porosities and numbers of reactivation cycles.

Perfluoroalkyl acids on suspended particles: Significant transport pathways in surface runoff, surface waters, and subsurface soils

ByPFAS Primer Team

These results suggest that suspended particles, often an overlooked vector for PFAAs, can be a dominant pathway for the transport of PFAAs in environments. July 13, 2021 | Journal of Hazardous Materials
