“…To reduce the environmental burden of PFAS, a stringent policy on prohibition and complete removal of contaminated materials needs to be enacted into law. There are many scientific reports utilizing various adsorbents in PFAS-contaminated sites [ 31 , 32 ]. An in situ detection, removal and destruction of PFAS in water looks attractive and could pave the way forward for reduced environmental contamination [ 33 ].…”

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.

The ubiquitous presence and persistence of per‐ and polyfluoroalkyl substances (PFAS) in the environment have raised concerns in the scientific community. Current research efforts are prioritizing effective PFAS remediation through novel sorbents with orthogonal interaction mechanisms. Recognized sorption mechanisms between PFAS and sorbents include hydrophobic, electrostatic, and fluorine‐fluorine interaction. The interplay of these mechanisms contributes significantly to improved sorption capacity and selectivity in PFAS separations. In this study, a primary/secondary amine‐functionalized polystyrene‐divinylbenzene (Sepra‐WAX) polymer was modified to create a fluorinated WAX resin (Sepra‐WAX‐KelF‐PEI). The synthesis intermediate (Sepra‐WAX‐KelF) was also tested to assess the improvement of the final product (Sepra‐WAX‐KelF‐PEI). The adsorption capacity of Sepra‐WAX, Sepra‐WAX‐KelF, and Sepra‐WAX‐KelF‐PEI, and their interactions with PFAS were evaluated. The effect of pH, ionic strength, and organic solvents on PFAS sorption in aqueous solution was also investigated. The sorbents showed varied adsorption capacities for perfluorooctanoic acid, perfluoropentanoic acid, perfluoro‐n‐decanoic acid, and hexafluoropropylene oxide dimer acid, with the average extraction capacity of the four analytes being Sepra‐WAX‐KelF‐PEI (523 mg/g) > Sepra‐WAX (353 mg/g) > Sepra‐WAX‐KelF (220 mg/g). Sepra‐WAX‐KelF‐PEI provided the highest adsorption capacity for all analytes tested, proving that the combination of electrostatic and hydrophobic/fluorophilic interactions is crucial for the effective preconcentration of PFAS and its future applications for PFAS remediation from aqueous solutions.
