This National Science Foundation project grant award of $492,628 supports collaborative research towards better understanding the atmospheric fate of per- and poly-fluoroalkyl substances (PFAS). Funded under the Geosciences program (CFDA 47.050), the research will quantify thermodynamic properties influencing PFAS phase partitioning, estimate atmospheric lifetimes against hydroxyl radical chemistry, and investigate reaction mechanisms. Beginning September 1, 2022 through August 31, 2025, the award supports one postdoctoral researcher at The Ohio State University to conduct laboratory experiments filling data gaps on PFAS chemistry and impacts. Specifically, the research will quantify properties like vapor pressure and acid dissociation constants influencing atmospheric distribution, use multiple oxidation flow reactors to constrain impacts of hydroxyl radicals, and estimate rate constants and potential reaction pathways. The award furthers the NSF's mission to advance fundamental geoscience knowledge through basic research.
