Environmental pollution is one of today's most urgent challenges, with severe consequences for human health and ecosystems. Perfluoroalkyl compounds (PFAS), known for their environmental persistence and potential negative effects, are among the most concerning contaminants. Used in various products, PFAS can pollute soil and water, entering the food chain. Agriculture, particularly viticulture, is vulnerable to this contamination, with vines potentially absorbing PFAS and transferring them into wine, posing risks to consumers and compromising the product's quality. The purpose of this study is to use biochar for the removal of these pollutants. After confirming that the wine tested positive for PFAS through mass spectrometry analysis, further analyses were conducted on water, soil, leaves, and grapes in each vineyard under study. The data obtained from biochar-treated and untreated sites were then compared to ultimately assess the effectiveness of biochar in retaining PFAS.
L'inquinamento ambientale è una delle sfide più urgenti di oggi, con gravi conseguenze per la salute umana e gli ecosistemi. I composti perfluoroalchilici (PFAS), noti per la loro persistenza ambientale e potenziali effetti negativi, sono tra i contaminanti più preoccupanti. Utilizzati in vari prodotti, i PFAS possono inquinare suolo e acqua, entrando nella catena alimentare. L'agricoltura, in particolare la viticoltura, è vulnerabile a questa contaminazione, con le viti che possono assorbire PFAS e trasferirli nel vino, creando rischi per i consumatori e compromettendo la qualità del prodotto. Lo scopo del presente elaborato è quello di utilizzare il biochar per la rimozione di questi inquinanti; dopo aver accertato che, come ci, si aspettava, il vino è risultato positivo all’analisi di PFAS, tramite spettrometro di massa sono state svolte analisi su acqua, suolo, foglie e uva in ciascun vigneto oggetto di studio. Sono stati poi confrontati i dati ottenuti dai siti trattati con biochar e non trattati al fine ultimo di valutare l’efficacia del biochar di trattenere i PFAS.

Abstract
Environmental pollution is one of today's most urgent challenges, with severe consequences for human health and ecosystems. Perfluoroalkyl compounds (PFAS), known for their environmental persistence and potential negative effects, are among the most concerning contaminants. Used in various products, PFAS can pollute soil and water, entering the food chain. Agriculture, particularly viticulture, is vulnerable to this contamination, with vines potentially absorbing PFAS and transferring them into wine, posing risks to consumers and compromising the product's quality. The purpose of this study is to use biochar for the removal of these pollutants. After confirming that the wine tested positive for PFAS through mass spectrometry analysis, further analyses were conducted on water, soil, leaves, and grapes in each vineyard under study. The data obtained from biochar-treated and untreated sites were then compared to ultimately assess the effectiveness of biochar in retaining PFAS.File | Dimensione | Formato | |
