The Effect of Selected Physicochemical Properties of Food-Contact Packaging Materials on the Efficiency of Per- and Polyfluoroalkyl Substances (PFAS) Isolation

To determine whether selected physicochemical properties of packaging materials—including the chemical nature of the matrix, surface hydrophobicity, morphological structure, and thermal properties—affect the effectiveness of PFAS isolation for compounds with varying chemical structures. The study will assess whether the observed differences in the recovery of specific PFAS groups are related to the properties of packaging materials and identify matrix characteristics relevant to the design of future studies on PFAS isolation.
