Biodegradation of per- and polyfluoroalkyl substances (PFAS): A review
Bioresource Technology, 2022 Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals widely manufactured for industrial and commercial applications in the past decades due to their remarkable stability as well as hydrophobic and lipophobic nature. PFAS species have been recognized as emerging environmental contaminants of concern due to their toxicity and environmental

Per- and Polyfluoroalkyl Substances (PFAS) in Street Sweepings
Environmental Science & Technology, 2021 One hundred and seventeen street sweeping samples were collected and analyzed for per- and polyfluoroalkyl substances (PFAS). Fifty-six samples were collected in one city (Gainesville, Florida) allowing for an in-depth city-wide characterization. Street sweepings from five other urban areas, (Orlando, n = 15; Key West, n = 15; Pensacola, n = 12; Tampa,

Review: Hydrothermal treatment of per- and polyfluoroalkyl substances (PFAS)
Chemosphere, 2022PER: and polyfluoroalkyl substances (PFAS) are a concerning and unique class of environmentally persistent contaminants with biotoxic effects. Decades of PFAS discharge into water and soil resulted in PFAS bioaccumulation in plants, animals, and humans. PFAS are very stable, and their treatment has become a global environmental challenge.

Two-step transformation of per- and polyfluoroalkyl substances (PFAS)
, 2023 In this project, I evaluated a two-step approach to breakdown of long-chain PFAS chemicals into innocuous byproducts. Ideally, UV-activated nanoparticles will cleave long-chain PFAS chemicals into shorter chains, and microbes will remove the fluorines from the smaller compounds.

Epigenetic changes by per- and polyfluoroalkyl substances (PFAS)
Environmental Pollution, 2021Increasing studies are examining per- and polyfluoroalkyl substances (PFAS) induced toxicity and resulting health outcomes, including epigenetic modifications (e.g., DNA methylation, histone modification, microRNA expression). We critically reviewed current evidence from human epidemiological, in vitro, and animal studies, including mammalian and ...

Per-and polyfluoroalkyl substances (PFAS): an emerging contaminant
Global NEST International Conference on Environmental Science & Technology, 2022PFAS compounds are ubiquitous in the environment and in consumer products. Unlike other emergent contaminants this is a family of compounds with, literally, thousands of compounds. Our knowledge of toxicological and environmental fate and transport properties is an evolving field. On the other hand, regulatory limits (when they exist) are extremely low

Per- and polyfluoroalkyl substances (PFAS) in livestock and game species: A review
Science of The Total Environment, 2021Per- and polyfluoroalkyl substances (PFAS) are synthetic, organic chemicals that resist environmental breakdown. The properties that made PFAS into an industrial success also led to their persistence and bioaccumulation. As PFAS were widely used for many decades their presence is evident globally, and their persistence and potential for toxicity create

An Integrated Approach for Determination of Total Per- and Polyfluoroalkyl Substances (PFAS)
Environmental Science & Technology, 2022Per- and polyfluoroalkyl substances (PFAS) are difficult to analyze in environmental media due challenges such as extraction recovery and lack of analytical standards. The total oxidizable precursor (TOP) assay and suspect screening analysis coupled with semiquantitative (SQ) concentration estimates are two approaches to assess total PFAS in ...
