The present study aims to determine perfluoroalkyl and polyfluoroalkyl substances (PFAS) in red wine samples using a validated ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC-MS/MS) method. A comprehensive analysis of red wines from various regions of northern Italy was conducted to assess the occurrence of PFAS. The results revealed considerable variability in PFAS species and concentrations, suggesting that grape cultivar and agricultural practices have a significant influence on PFAS accumulation. Furthermore, targeted analyses of leaf, grape, pomace, soil, and water samples from a representative vineyard were conducted to investigate the distribution of these compounds within the vineyard ecosystem, demonstrating distinct accumulation trends of PFAS across environmental matrices. These findings offer insight into the distribution of PFAS in viticulture environments and highlight the need for ongoing monitoring and mitigation strategies to ensure the safety and quality of wine products. Additionally, the data indicate that although organic farming practices can effectively reduce chemical residues, environmental contamination remains a persistent challenge that must be addressed to protect consumer health and promote environmental sustainability.

Abstract
The present study aims to determine perfluoroalkyl and polyfluoroalkyl substances (PFAS) in red wine samples using a validated ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC-MS/MS) method. A comprehensive analysis of red wines from various regions of northern Italy was conducted to assess the occurrence of PFAS. The results revealed considerable variability in PFAS species and concentrations, suggesting that grape cultivar and agricultural practices have a significant influence on PFAS accumulation. Furthermore, targeted analyses of leaf, grape, pomace, soil, and water samples from a representative vineyard were conducted to investigate the distribution of these compounds within the vineyard ecosystem, demonstrating distinct accumulation trends of PFAS across environmental matrices. These findings offer insight into the distribution of PFAS in viticulture environments and highlight the need for ongoing monitoring and mitigation strategies to ensure the safety and quality of wine products. Additionally, the data indicate that although organic farming practices can effectively reduce chemical residues, environmental contamination remains a persistent challenge that must be addressed to protect consumer health and promote environmental sustainability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
