Molecular Connectivity Indices and Soil Properties to Predict Sorption of Per- and Polyfluoroalkyl Substances

AI summary Read the abstract

This study developed a model using molecular connectivity indices and soil physicochemical properties to predict soil-water partitioning coefficients for PFAS compounds, enabling more accurate assessment of their environmental fate. PFAS compounds are persistent co-contaminants that sorb to microplastic surfaces, so improved partitioning models directly support understanding of how plastic particles act as vectors concentrating these chemicals in soil environments.

This study presents a modeling approach to predict soil-water partitioning coefficient (log Kd, L/kg) for per- and polyfluoroalkyl substances (PFAS) as a function of molecular connectivity indices (MCIs) and soil...

Effects of Co-Existing Microplastics on Adsorption–Desorption Behavior of Perfluorooctanoic Acid in Soil: Co-Sorption and Mechanism Insight

AI summary Read the abstract

Researchers investigated how microplastics affect perfluorooctanoic acid (PFOA) adsorption in agricultural soil, finding that irregularly shaped microplastics augmented PFOA adsorption through altered functional groups, with kinetics following a quasi-second-order model and isotherms fitting the Freundlich model, indicating microplastics can modify PFOA environmental behavior in agroecosystems.

Adsorption of PFAS onto secondary microplastics: A mechanistic study

AI summary Read the abstract

Researchers investigated how PFAS (per- and polyfluoroalkyl substances) adsorb onto secondary microplastics under different water chemistry conditions. Results showed that PFAS adsorption depended on both the chemical structure of the PFAS compound and the ionic composition of the water. These findings help explain how microplastics in real-world aquatic environments can concentrate and transport PFAS, a group of persistent health-relevant pollutants.

Adsorption of Forever Chemical Pollutants: The Physical Chemistry of PFAS near Surfaces

AI summary Read the abstract

This review provides a comprehensive analysis of the physical chemistry governing how per- and polyfluoroalkyl substances (PFAS) adsorb onto solid surfaces, covering molecular interactions, thermodynamics, kinetics, and the influence of environmental variables like pH and salinity. The authors identify critical knowledge gaps that currently limit the development of effective adsorption-based remediation strategies for these persistent 'forever chemical' pollutants.
