The University of Florida, Division of Sponsored Research, was awarded a $555,199 project grant from the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) to conduct a 3-year study on the fate, trophic uptake, and toxicity of per- and polyfluoroalkyl substances (PFAS) in the Indian River Lagoon, Florida. The key objectives are to: (1) characterize the seasonal diversity and concentration of 90 PFAS in water, sediment, and seagrass; (2) determine the partitioning of PFAS in the sediment-water interface under changing physicochemical conditions; and (3) assess PFAS trophic uptake and toxicity to aquatic organisms through laboratory microcosm studies. The expected outcomes include new data on PFAS spatiotemporal patterns, partition coefficients, microbial community impacts, gene expression, and toxicology across multiple trophic levels in the estuary.
