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. Methods The Italian National Institute Health pre-processed made available anonymous data from Statistics death certificate archives residents Vicenza, Padua Verona (males, n = 29,629; females, 29,518) who died Calendar analysis done calculating standardised ratios using total same as reference. performed 20–84 years cumulative ratios.

PFAS contamination is a global issue, affecting various food sources, especially animal-based products like eggs and dairy. Collect scientific evidence of the presence in diverse edible resources along with related risks to human health, pursuing following objectives: determination level terrestrial chain contamination; health risk. Scopus, PubMed, Web Science databases. 4952 papers published from January 2013 August 2024 were retrieved at end selection process, 40 studies included. Clear description methodology used for detection; relevance or species, their parts, intended consumption; assessment Higher number China, 17, Italy 6 studies. The most detected PFOA PFOS.

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. Detailed characterization using scanning electron microscopy-energy dispersive X-ray spectroscopy, Fourier transform infrared, thermogravimetric analysis, diffraction, photoelectron spectroscopy confirmed proposed mechanisms, including electrostatic hydrophobic Interestingly, not influenced solution pH, ionic strength, or natural matter.

Driven by the global popularity of electric vehicles and shortage critical raw materials for batteries, spent lithium-ion power battery (LIPB) recycling industry has exhibited explosive growth in both quantity scale. However, relatively little information is known about environmental risks posed LIPB recycling, particular with regards to perfluoroalkyl polyfluoroalkyl substances (PFAS). In this work, suspect screening nontarget analysis were carried out characterize PFAS soil, dust, water sediment from a area. Twenty-five nine classes identified at confidence level 3 or above, including 13 legacy 12 emerging PFAS, as well two ultrashort-chain PFAS. Based on target 16 least detected each sample, indicating their widespread presence Perfluorodecanoic acid, perfluorooctanesulfonic acid trifluoromethanesulfonamide showed significant differences four phenotypic parameters (growth, movement, survival fecundity)
