Per- and polyfluoroalkyl substances (PFAS) are diverse synthetic chemicals manufactured over seven decades. It is an aliphatic molecule with a basic hydrophobic structure of carbon fluorine linked to hydrophilic end group. Due their physicochemical properties associated the unique structure, PFAS has been used in wide variety applications including aqueous film-forming foams (AFFF), paper, carpets, non-stick cookware, etc. as they make products resistant water, heat, stains. These molecules have drawn great attention recently for properties, high stability low degradability, so-called “Forever Chemicals”. strongest carbon-fluorine bond which makes them persistent environment. Hence it contaminates natural resources endangers public health. This review discusses discovery, development, evolution from wonder chemical era nightmare era, exposure its impacts on human health environment, current remediation techniques, future trends related products. The primary objective this identify knowledge gaps contamination, methods, possible alternatives.

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous environmental contaminants that often co-occur with heavy metals. Despite their prevalence, the mobility of PFAS in complex, multicomponent systems, particularly at molecular scale, remains poorly understood. The vast diversity low concentrations alongside anthropogenic natural underscore need for integrating mechanistic insights into sorption models. This study explores influence metal cations (Cu(II), Cd(II), Fe(II)) on adsorption four common (PFOA, PFOS, PFDA, GenX) onto goethite (α-FeOOH), a iron (oxyhydr)oxide both aquatic terrestrial environments. was highly dependent type, pH, ion concentration, surface complexation model effectively predicting these interactions. Cu(II) Cd(II) enhanced PFOS PFDA via ternary while slightly reducing PFOA GenX adsorption. Under anoxic conditions, Fe(II) significantly increased all PFAS, showing reactivity greater than those Cd(II). Additionally, organic matter mobility, although groundwater may counteract this by enhancing retention. These findings highlight key role transport offer critical behavior oxic-anoxic interfaces.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants that have been in use industrially since the 1940s. Their long-term extensive commercial has led to their ubiquitous presence environment. The ability measure bioconcentration distribution PFAS tissue aquatic organisms helps elucidate persistence as well environmental impacts. Traditional analysis by LC-MS/MS can total concentrations within an organism but cannot provide comprehensive spatial information regarding organism. In current study, we used infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) determine limit detection (LOD) several utilizing standard mix spotted on mouse liver tissue. traditional ice matrix alternative matrix, 1,8-bis (tetramethylguanidino)naphthalene (TMGN), were explored when determining limits for various IR-MALDESI. alone resulted higher response than combination TMGN ice. resulting LOD perfluorooctane sulfonic acid (PFOS) per voxel basis was 0.16 fmol/voxel. For comparison, zebrafish exposed perfluorooctanoic (PFOA), PFOS, perfluorohexanesulfonic (PFHxS) at different homogenized, extracted solid-liquid extraction, purified solid phase analyzed level bioaccumulation zebrafish. PFOS highest (731.9 μg/kg, or 234.2 fg/voxel). A had mixture PFOA (250 ng/L), PFHxS (125 ng/L) cryosectioned Images could not be generated accumulation sectioned below technique.
