Extraction, transport, and transformation of poly- and perfluoroalkyl substances in soils impacted by aqueous film-forming foam
Poly- and perfluorinated alkyl substances (PFASs) are a class of recalcitrant environmental contaminants used in a variety of industries and consumer products. Use of aqueous film-forming foams (AFFF) at military bases and airports is one significant source of PFAS contamination to groundwater and …

Mechanistic insights on the merits and limitations of advanced treatment processes for removal of contaminants of emerging concern
Perfluoroalkyl substances (PFASs) are recalcitrant contaminants of emerging concern that have widespread distribution in water sources, and exhibit potential to persist and bioaccumulate. Non-destructive and destructive remediation strategies have been actively investigated to remove PFAS. …

Development of a Novel Perfluoroalkyl Substance Sequestration Scheme Using Alginate Macrobeads and Common Water Treatment Polymers
Groundwater contamination by perfluoroalkyl substances (PFASs) is a topic of growing concern. Preventing transport via sorption-enhancement to aquifer material is a potential solution to this problem. Two models of osmotic surgical implant pumps were used to demonstrate that the cationic polymers …

Analysis of antibiotics and PFAS as potential emerging pollutants in the water bodies and their accumulation in food samples
Antibiotics and perfluoroalkyl substances (PFAS) are groups of anthropogenic substances that are found in industries and consumer products, i.e., antibiotics are used in healthcare facilities, pharmaceutical companies, and agriculture, whereas PFAS are used in industries and households. These …

Fate and remediation of emerging organic contaminants in aquatic and soil environments
… recalcitrant CEC structures (e.g., poly- and perfluoroalkyl substances (PFASs)) that have been increasingly detected in aquatic systems. The removal of 75 PFASs was assessed using 14 commercially available ion-exchange (IX)/non-ionic resins and granular activated carbon (GAC). Among the …

DETERMINATION OF CONTAMINANTS IN FISHERY PRODUCTS TO SUPPORT FOOD SAFETY
… [1] and Persistent bioaccumulative toxic substances (PBTs), Potentially Toxic Elements (PTEs), whose study remains crucial for consumer protection; Perfluoroalkyl Substances (PFASs) some of which are POPs and Microplastics (MPs); these two classes have been particularly considered due to …

Rigenerazione mediante irradiamento a microonde di carboni attivi saturi da contaminanti emergenti
La presenza di contaminanti emergenti (Contaminants of emerging concern, CEC) in tracce nei comparti acquatici è attualmente oggetto di studio e monitoraggio a causa dei lori effetti avversi (comprovati o potenziali) sulla salute umana e il loro impatto negativo sugli ecosistemi. Tra i CEC di …
