The frequent detection of PFASs in various environments and biotas, which incurs people’s awareness about PFASs’ geochemical behavior. Although there was much research on the fate of PFASs, they mostly focus on the atmosphere and hydrosphere. The underlying reactive mechanism of PFASs with soil reactive components is still poorly research and urgently needs to explore. The current study just reveals the mechanism by simply empirical model lacking theoretical basis and the parameter always changes by different conditions, which limits their applicability and development. Here, we plan to establish a new model to precise predict their behavior in soil environments.
This study mainly aims to obtain a scientific understanding of the interactions of PFASs with the reactive components in soils: particulate and dissolved organic matter, metal-oxides, and clays. Then, develop a mechanistic model for PFASs behavior in soils and validation on real soil environments. Finally, estimate the method of extract available PFASs concentration.
