Per- and polyfluoroalkyl substances in the environment

Science, 2022
Over the past several years, the term PFAS (per- and polyfluoroalkyl substances) has grown to be emblematic of environmental contamination, garnering public, scientific, and regulatory concern. PFAS are synthesized by two processes, direct fluorination (e.g., electrochemical fluorination) and oligomerization (e.g., fluorotelomerization).

Per- and polyfluoroalkyl substances

2023
er- and polyfluoroalkyl substances (PFASs) are anthropogenic contaminants of emerging concern that are ubiquitous in the marine environment. This chapter provides recent insights into the main aspects of research on this class of compounds in the oceans.

Epigenetic changes by per- and polyfluoroalkyl substances (PFAS)

Environmental Pollution, 2021
Increasing 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) 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,

Per/polyfluoroalkyl substances production, applications and environmental impacts

Bioresource Technology, 2021
The per/polyfluoroalkyl substances (PFAS) are growing contaminants which are extremely difficult to get degraded naturally. PFAS have been produced for nearly a century using electrochemical flourination and more relomerization processes. High chemical resistance, hydrophobicity, lipophobicity, heat resistace, extremly low friction coefficient make ...

Association between per- and polyfluoroalkyl substances and semen quality

Environmental Science and Pollution Research, 2022
Some studies have suggested that perfluoroalkyl and polyfluoroalkyl substance (PFAS) exposure may be associated with semen quality in the general population, but with inconsistent results. To identify a more precise relationship between them, a meta-analysis was performed. We searched Embase, the PubMed, The Cochrane Library, Ovid databases, and Web of

Phytoremediation prospects of per- and polyfluoroalkyl substances: A review

Environmental Research, 2022
Extensive use of per- and polyfluoroalkyl substances (PFASs) in various industrial activities and daily-life products has made them ubiquitous contaminants in soil and water. PFAS-contaminated soil acts as a long-term source of pollution to the adjacent surface water bodies, groundwater, soil microorganisms, and soil invertebrates.

Review: Hydrothermal treatment of per- and polyfluoroalkyl substances (PFAS)

Chemosphere, 2022
PER: 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.

Recovery of per- and polyfluoroalkyl substances after solvent evaporation

Environmental Science: Processes & Impacts, 2022
Presented data shows that vacuum evaporative concentration of PFAS standards can cause class-specific loss of material that can be mitigated via recovery steps.
