Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals prized for their water, grease, and stain-resistant properties [3], [19]. They are persistent in the environment and the human body, leading to concerns about potential health impacts [3], [24].
PFAS are a diverse group of thousands of synthetic chemicals characterized by a chain of carbon atoms with fluorine atoms attached [1], [4], [8], [15]. This structure gives them unique properties such as being water, grease, and stain-resistant, as well as thermally and chemically stable [3], [8], [17].
Éleuthère Irénée du Pont founded E. I. du Pont de Nemours and Company (DuPont) [26].
John Dwan, Hermon Cable, Henry Bryan, and William A. McGonagle co-founded Minnesota Mining and Manufacturing Company (3M) [26].
General Motors and DuPont formed Kinetic Chemicals to produce Freon [26].
Synthesis of polytetrafluoroethylene (PTFE), the first known PFAS compound [8].
PFAS introduced to the world as Teflon by DuPont [19].
Extensive industrial, commercial, and consumer applications of PFAS began [17].
Development of PFAS-containing aqueous film-forming foam (AFFF) for firefighting [38].
FDA first raised safety concerns with certain PFAS substances [18].
Grandjean and Weihe investigated the impact of PFAS on the immune system [21].
Grease-proofing agents containing C8 compounds stopped being used for food contact in the U.S. market between 2011 and 2016 [18].
FDA obtained market-phase-out commitment letters for grease-proofing agents containing 6:2 FTOH [18].
The European Commission recommends Member States to monitor the presence of PFAS in food from 2022 to 2025 [3].
FDA received confirmation from manufacturers of all remaining authorized grease-proofing substances containing PFAS that they would no longer sell these substances in the U.S. market [18].
The first PFAS compound, polytetrafluoroethylene (PTFE), was synthesized in 1938, leading to increased production due to its valuable surfactant, oil-repellent, and water-repellent qualities [8].
First appeared: 1938
PFAS exposure has been associated with immunotoxicity, endocrine disruption, metabolic disorders, and carcinogenicity [13].
Studies suggest that PFAS can accumulate in the brain and may have neurotoxic effects [8], [15].
Prenatal exposure to PFAS has been linked to increased blood pressure in adolescents [24].
Association Between Exposure to Per- and Polyfluoroalkyl Substances and Birth Outcomes: A Systematic Review and Meta-Analysis
This study found associations between PFAS exposure and adverse birth outcomes [6].
Per- and Polyfluoroalkyl Substance Toxicity and Human Health Review: Current State of Knowledge and Strategies for Informing Future Research
This review provides an overview of PFAS toxicity and its effects on human health [7].
Neurotoxicity of per- and polyfluoroalkyl substances: Evidence and future directions
Emerging evidence suggests a potential link between PFAS exposure and neurotoxic effects, spanning cognitive deficits, neurodevelopmental disorders, and neurodegenerative diseases [15].
Per- and polyfluoroalkyl substances (PFAS) and cancer: Detection methodologies, epidemiological insights, potential carcinogenic mechanisms, and future perspectives
Recent reviews have predominantly emphasized advancements in the detection, adsorption, and degradation of PFAS through their chemical structures and toxic properties; however, further examination of the literature is needed to determine the link between PFAS exposure and cancer risk [16].
Concerning. Exposure to some types of PFAS has been linked to serious health effects [4].
While many studies focus on long-chain PFAS like PFOA and PFOS, there is a growing need for research on short-chain PFAS and other less-studied PFAS compounds [8].
