摘要：As an emerging pollutant, polyfluoroalkyl substances (PFASs) are of significant concern globally, yet the contamination characteristics and sources of PFASs in the cultivation base for the production of raw materials, specifically Hongyingzi sorghum, represented by Moutai Wine, remain largely unknown. In this study, PFASs was tested for the first time in tilled soil (0-20 cm) across eight sample sites in the Hongyingzi sorghum cultivation base using liquid chromatography-triple quadrupole mass spectrometry (LC-TQMS). Two legacy PFASs and five emerging PFASs were detected, with Sigma 7PFAS concentrations ranging from 87.8 to 446 ng/kg and an average concentration of 248 +/- 106 ng/kg. The Sigma PFAS concentrations, predicted using the ordinary kriging method, were relatively uniform across most of the study area, ranging from 232 to 234 ng/kg. The emerging PFASs contributed 41.8% to the Sigma 7PFASs, and short-chain fluorine-containing products were identified as the primary substitutes for perfluorooctanoic acid (PFOA) in the study area. The principal component analysis results suggested that PFAS pollution originated from PFOA, perfluorononanoic acid, perfluorobutanoic acid, perfluoropentanoic acid, and perfluoroheptanoic acid, which are linked to rural living and agricultural activities, as well as perfluorobutanesulfonic acid, which is associated with industrial activities. The ecological risk assessment indicated that PFOA in the soils in the study area poses a very low ecological risk. In addition, the health risk assessment revealed that the PFASs in the soil do not present a significant risk to human health. These findings provide a scientific basis for the prevention, control, and management of PFAS pollution in the Hongyingzi sorghum cultivation base.
