Interactive mechanisms between pfas and soil characteristics: a review

Abstract

Studies related to the interaction of PFAS (per- and polyfluoroalkylated) substances in soil media are essential for finding means of removal from the environment. This review focuses on the most important soil characteristics, such as pH, temperature, organic matter and nutrient content, potentially toxic elements, soil particle size distribution, total nitrogen content and cation exchange capacity, which determine the different interactions of PFAS in soil media, analysing the sorption mechanism at a deeper level. In addition, the analysis of the interaction of PFAS with soil properties is important for predicting the sorption of PFAS in soil. The requirement for an effective PFAS removal method and methodology with threshold values is greatly influenced by the properties of the medium, environmental conditions and PFAS characteristics. This review discusses the most important features of the interaction between PFAS and soil properties and the mechanisms of PFAS sorption in soil.
