“…Foam fractionation can efficiently remove PFAS in the liquid media because the perfluoroalkyl groups shift to the gas-fluid interface, and ozone oxidizes and degrades organic molecules. Although ozone (O 3 ) has only been explored in small-scale experiments for the cleanup of PFAS in water, it has been shown to achieve removal rates > 97% in a sensible procedure time [128]. Full-scale assessment employing ozofractionation for PFAS elimination proved to be successful, as reported by Horst et al (2018).…”

Per and polyfluoroalkyl substances (PFAS) have been extensively employed in a broad range of manufacturing and consumer goods due to their highly persistent nature. PFAS exposure is recognized to pose serious health hazards; therefore, addressing PFAS pollution in water has become a top priority for public health and environmental protection organizations. This review article focuses on the efficiency of different removal techniques (activated carbon, biochar, ion exchange resin, membrane filtration, reverse osmosis, metal-organic frameworks, foam fractionation, ozone fractionation, and destruction techniques) for eliminating different types of short- and long-chain PFAS from water. Hydrophobicity and electrostatic interactions are revealed to be the primary mechanisms for the elimination of PFAS. The efficiency of all techniques to eradicate short-chain PFAS is comparatively lower compared to long-chain PFAS. The destruction techniques are the most efficient but have some drawbacks, including the formation of PFAS precursors and high operational costs. According to the findings from the study, it is anticipated that combined methods will be required to effectively remediate PFAS-contaminated water.

Perfluoroalkylated and polyfluoroalkylated substances (PFAS) are a large family of synthetic chemicals widely used to manufacture various commercial products. However, they are hazardous to health and the environment. These substances are very persistent and their degradation requires advanced degradation techniques. One of the most widely used technologies for this purpose is advanced oxidation processes (AOP). This study aims to evaluate the use of AOP in PFAS degradation based on their efficiency, parameters influencing each process, advantages, disadvantages, and associated research challenges. According to the results, plasma, electrochemical oxidation, sonochemical oxidation, and heterogeneous photocatalysis stand out among the AOP applied for PFAS degradation. In addition, perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) were found to be the main toxic compounds studied. In this regard, future research should focus on a wider variety of PFAS. Finally, the drawbacks associated with the application of these processes to eliminate the substances of interest were found to be an urgent need to be overcome.

“…An in situ detection, removal and destruction of PFAS in water looks attractive and could pave the way forward for reduced environmental contamination [ 33 ]. However, removal efficiencies of PFAS in various environmental media (such as soil, air or water) could be daunting due to varying chemical interactions [ 34 ].…”

This exploratory narrative review paper delves into the intricate interplay between per- and polyfluoroalkyl substances (PFAS) exposure, sociodemographic factors, and the influence of stressors in the context of endometrial cancer. PFAS, ubiquitous environmental contaminants notorious for their persistence in the ecosystem, have garnered attention for their potential to disrupt endocrine systems and provoke immune responses. We comprehensively examine the various sources of PFAS exposure, encompassing household items, water, air, and soil, thus shedding light on the multifaceted routes through which individuals encounter these compounds. Furthermore, we explore the influence of sociodemographic factors, such as income, education, occupation, ethnicity/race, and geographical location and their relationship to endometrial cancer risk. We also investigated the role of stress on PFAS exposure and endometrial cancer risk. The results revealed a significant impact of sociodemographic factors on both PFAS levels and endometrial cancer risk. Stress emerged as a notable contributing factor influencing PFAS exposure and the development of endometrial cancer, further emphasizing the importance of stress management practices for overall well-being. By synthesizing evidence from diverse fields, this review underscores the need for interdisciplinary research and targeted interventions to comprehensively address the complex relationship between PFAS, sociodemographic factors, stressors, and endometrial cancer.
