Pollutants, Journal Year: 2024, Volume and Issue: 4(1), P. 136 - 152

Published: March 6, 2024

Per- and polyfluoroalkyl substances (PFAS) belong to a group of synthetic compounds that have recently raised concerns about human health environmental quality due their great prevalence, degradation resistance, potential toxicity. This review focuses on the applications PFAS effects health. Specific emphasis has been laid (i) application/use PFAS, (ii) sources distribution in diverse compartments, (iii) impact Significant humans are associated with exposure i.e., immunotoxicity, thyroid kidney disorders, cancer, etc. Conclusions obtained from studies demonstrate inadequate evidence should not be used justify delaying risk reduction steps for alternatives. can determined different matrices using both traditional analytical approaches, liquid chromatography coupled mass spectrometry (LC-MS/MS) semi-quantitative passive sampling, advanced methods colorimetric, spectrofluorimetric, electrochemical detection. Traditional costly broadly available, while emerging, cost-effective less sensitive unable meet regulatory limits. There is still significant number performed fully comprehend real contamination by PFAS.

Abstract Background Per- and polyfluoroalkyl substances (PFAS) are associated with many adverse health conditions. Among the main effects is carcinogenicity in humans, which deserves to be further clarified. An evident association has been reported for kidney cancer testicular cancer. In 2013, a large episode of surface, ground drinking water contamination PFAS was uncovered three provinces Veneto Region (northern Italy) involving 30 municipalities population about 150,000. We report on temporal evolution all-cause mortality selected cause-specific by calendar period birth cohort local between 1980 2018.

PFAS Contamination in Europe: Generating Knowledge and Mapping Known and Likely Contamination with “Expert-Reviewed” Journalism

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(15), P. 6616 - 6627

Published: April 3, 2024

While the extent of environmental contamination by per- and polyfluoroalkyl substances (PFAS) has mobilized considerable efforts around globe in recent years, publicly available data on PFAS Europe were very limited. In an unprecedented experiment "expert-reviewed journalism" involving 29 journalists seven scientific advisers, a cross-border collaborative project, "Forever Pollution Project" (FPP), drew both methods investigative journalism techniques such as open-source intelligence (OSINT) freedom information (FOI) requests to map across Europe, making public that previously had existed "unseen science". The FPP identified 22,934 known sites, including 20 manufacturing facilities, 21,426 "presumptive sites", 13,745 sites presumably contaminated with fluorinated aqueous film-forming foam (AFFF) discharge, 2911 industrial 4752 related PFAS-containing waste. Additionally, 231 "known users", new category for intermediate level evidence use considered likely be sources. However, true remains significantly underestimated due lack comprehensive geolocation, sampling, data. This model knowledge production dissemination offers lessons researchers, policymakers, about cross-field collaborations transparency.

Surface Modification of Graphene Oxide for Fast Removal of Per- and Polyfluoroalkyl Substances (PFAS) Mixtures from River Water

ACS ES&T Water, Journal Year: 2024, Volume and Issue: 4(7), P. 2968 - 2980

Published: June 11, 2024

Per- and polyfluoroalkyl substances (PFAS) make up a diverse group of industrially derived organic chemicals that are significant concern due to their detrimental effects on human health ecosystems. Although other technologies available for removing PFAS, adsorption remains viable effective method. Accordingly, the current study reported novel type graphene oxide (GO)-based adsorbent tested removal performance toward PFAS from water. Among eight adsorbents tested, GO modified by cationic surfactant, cetyltrimethylammonium chloride (CTAC), GO-CTAC was found be best, showing an almost 100% all 11 tested. The kinetics were best described pseudo-second-order model, indicating rapid adsorption. isotherm data well supported Toth suggesting onto involved complex interactions.

Abstract Background The family of perfluoroalkyl and polyfluoroalkyl substances (PFAS) raised concern for their proven bioaccumulation persistence in the environment animals as well hazardous health effects. As a result, new congeners PFAS have rapidly replaced so-called “old long-chain PFAS” (mainly PFOA PFOS), currently out-of-law banned by most countries. These compounds derive from original structure PFAS”, cutting or making little conformational changes to structure, thus obtaining molecules with similar industrial applications. were designed obtain "safer" compounds. Indeed, old-long-chain reported exert thyroid disruptive effects vitro, vivo humans. However, shreds evidence accumulated so far indicate that “restyling” old leads production compounds, not only functionally previous ones but also potentially free adverse bioaccumulation. Studies aimed at characterizing new-PFAS on function some these showed Purpose present review is providing an overview recent data regarding novel alternatives function. Results conclusions An extensive current legislation obtained vitro studies evaluating exposure PFOS alternatives, mixture will be provided.
