Per- and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals that globally used in various commercial products like cloths, carpets, cookware, firefighting foams, cosmetics, electronic products, etc. Inappropriate disposal these consumer could lead to environmental contamination with PFAS. Nowadays short-chain PFAS substituting the long chain due their short half-life. However, multiple studies have suggested such as Perfluorohexanoic acid (PFHxA) Perfluorohexanesulfonic (PFHxS) modulate antioxidant enzyme activities, induce Reactive Oxygen Species production, contribute oxidative stress organisms. Notably, experimental set-ups aiming investigate mode action compounds on antioxidants entirely lacking. Hence present study, ligand-docking approach was adopted potential intermolecular interactions between major Glutathione peroxidase-4, reductase, S-Transferase, Catalase, Superoxide dismutase-1. Three-dimensional structures proteins were processed docked individually PFHxA PFHxS using AutoDock vina.. Results indicated significant binding affinities Interestingly, non-covalent H-bonds, van der Waals, CH bonds, halogen alkyl/pi-alkyl apparent at protein-ligand interface. Hence, results suggest both may potentially interact endogenous this outcome can be detrimental redox homeostasis living

Limited information is available about prenatal exposure to per- and polyfluoroalkyl substances (PFAS) in electronic waste (e-waste) recycling sites. In this study, we determined 21 emerging PFAS 13 legacy 94 paired maternal cord serum samples collected from an e-waste dismantling site Southern China. We found 6:2 fluorotelomer sulfonate (6:2 FTSA), chlorinated polyfluorinated ether Cl-PFESA), perfluorooctanephosphonate (PFOPA) as the major PFAS, regardless of matrices, at median concentrations 2.40, 1.78, 0.69 ng/mL, respectively, samples, 2.30, 0.73, 0.72 samples. Our results provide evidence that activities contribute human FTSA, Cl-PFESA, PFOPA. The trans-placental transfer efficiencies (0.42–0.94) were higher than perfluorooctanesulfonic acid (0.37) structure-dependent. substitution fluorine with chlorine or hydrogen and/or hydrophilic functional groups may alter efficiencies. Multiple linear regression analysis indicated significant associations between clinical parameters, especially liver function erythrocyte-related biomarkers. This study provides new insights into multiple areas prevalence people living near
