Occupational exposures to airborne per‐ and polyfluoroalkyl substances (PFAS)—A review

American Journal of Industrial Medicine, 2023
AbstractBackgroundPer‐ and polyfluoroalkyl substances (PFAS) are a group of synthetically‐made chemicals with diverse functional properties that have become ubiquitous in our environment because of their widespread use. PFAS exposure has been associated with adverse health effects, and it is therefore vital to know how exposure may occur.

Removing per- and polyfluoroalkyl substances (PFAS) in water by foam fractionation

Chemosphere, 2023
Treatment of large volumes of waters contaminated by per- and polyfluoroalkyl substances (PFAS) remains a challenge. This work presented a systematic study on PFAS removal by foam fractionation (FF). Experiments were conducted on both laboratory-spiked and environmental water samples containing PFASs.

Prevalence and Implications of Per- and Polyfluoroalkyl Substances (PFAS) in Settled Dust

Current Environmental Health Reports, 2021
Per- and polyfluoroalkyl substances (PFAS) are a family of more than 7,000 fluorinated compounds. The carbon-fluorine bond of PFAS provides desirable hydrophobic and oleophobic properties and stability that has led to widespread usage in consumer products and industrial applications.

Ecological Considerations of Per- and Polyfluoroalkyl Substances (PFAS)

Current Pollution Reports, 2017
Per- and polyfluoroalkyl substances (PFASs) have been detected around the globe in drinking water, in various media at release sites, in human blood serum, and in non-human biota tissue. These compounds are emerging contaminants due to the rapidly evolving regulatory landscape, which is driven by advances in toxicological and risk assessment knowledge ...

Indoor exposure to per- and polyfluoroalkyl substances (PFAS) in the childcare environment

Environmental Pollution, 2020
Per- and polyfluoroalkyl substances (PFAS) are widely used in stain-resistant carpets, rugs, and upholstery, as well as in waxes and cleaners, and are potential contaminants in the childcare environment. However, limited knowledge exists on the occurrence of PFAS in indoor environments, apart from residential homes.

Bioaccumulation, fate, and treatment of per- and polyfluoroalkyl substances (PFAS)

2023
Per- and polyfluoroalkyl substances (PFAS) are a large and diverse class of man-made chemicals that are persistent and difficult to degrade in the environment. PFAS are characterized by the presence of carbon-fluorine bonds, the strongest bond in organic chemistry, which leads to great thermal and chemical stability.

Per- and polyfluoroalkyl substances (PFAS) in the marine environment: An overview and prospects

Marine Pollution Bulletin
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals known for their excellent persistence and surface activity. PFAS can be readily transported through waterways into the ocean, which serves as their primary global sink. This review summarizes recent studies on PFAS in the marine environment and outlines some key directions for future ...
