The scientific community’s understanding of the health and environmental effects of PFAS is evolving at a rapid pace. At the same time, researchers are developing new technologies to assess and remediate PFAS contamination. This section provides the latest updates on developments in PFAS-related science and technology.

The Food and Drug Administration’s (FDA) Total Diet Study (TDS) collects foods that are both nationally and regionally distributed. The study concludes that additional occurrence data are needed to better understand human exposure to per- and poly-fluoroalkyl substances (PFAS) from commercially available foods in the United States.

This review focuses on how plants, microbe, substrate can influence PFASs removal in wetlands under natural and controlled conditions.

Based on information from both human observational studies and clinical data, this study proposed a range for the half-life for PFOA of 0.5 to 1.5 years, which would likely raise many existing regulatory safe levels if all other parameters stayed the same.

Thermal decomposition of high-fluorine content PFAS streams for the disposal of old generations of concentrates of firefighting foams, exhausted ion-exchanged resins and granular activated carbon, constitutes the preferred method for destruction of these materials.

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.
