ClearMechanistic Insights into PFAS Adsorption on Microplastics: Effects of Contaminant Properties and Water Chemistry
Researchers investigated how two widely detected PFAS compounds, PFOS and PFOA, adsorb onto five common types of microplastics in aquatic environments. The study found that contaminant properties and water chemistry significantly influence adsorption behavior, confirming that microplastics can serve as carriers for PFAS transport in waterways.
A tale of two emerging contaminants: Interfacial interactions, co-transport behaviors and ecotoxicological implications between per-and polyfluoroalkyl substances and micro(nano)plastics.
This review examined how PFAS and micro/nanoplastics co-occur in the environment, form interfacial adsorption complexes, and interact synergistically within organisms. The authors found that the two contaminant classes amplify each other's toxicity in co-exposure scenarios and that their shared transport pathways complicate standard risk assessment.
Review of Recent Computational Research on the Adsorption of PFASs with a Variety of Substrates
This review summarizes recent computer modeling research on how PFAS, sometimes called "forever chemicals," stick to various materials, which could help develop better cleanup methods. While focused on PFAS rather than microplastics, both are persistent environmental pollutants that resist breakdown and accumulate in the body. Understanding how these chemicals interact with surfaces at the molecular level could lead to more effective ways to remove them from contaminated water and soil.
Interactions between MPs and PFASs in aquatic environments: A dual-character situation
This review examines the interactions between microplastics and per- and polyfluoroalkyl substances (PFAS) in water environments, finding that the two pollutants have a complex relationship. Microplastics can absorb PFAS chemicals onto their surfaces, potentially transporting them through aquatic systems and altering their environmental behavior. The study highlights the need to consider these combined effects when assessing pollution risks in waterways.
From co-occurrence to co-existence and co-exposure: Associations between per- and polyfluoroalkyl substances and microplastics in the environment
This review examines the growing recognition that PFAS chemicals and microplastics frequently co-occur in the environment and may interact in ways that affect both ecological and human health. Researchers identified four major sources that emit both pollutants simultaneously and found strong evidence that PFAS can adsorb onto microplastic surfaces and be co-transported through the environment. The study calls for standardized methods and long-term studies to better understand the combined exposure risks of these two widespread contaminant classes.
Interaction of microplastics with perfluoroalkyl and polyfluoroalkyl substances in water: A review of the fate, mechanisms and toxicity
This review examines how microplastics act as carriers for PFAS ("forever chemicals") in water, with the two pollutants interacting through various chemical mechanisms that affect their movement through the environment. The combined presence of microplastics and PFAS raises concerns about increased toxicity, since microplastics can transport these persistent chemicals into organisms and potentially concentrate their harmful effects.
Adsorption of PFAS onto secondary microplastics: A mechanistic study
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.

Polypropylene nanoplastics as PFAS carriers: A computational study of the adsorption mechanism
Researchers used computational modeling to investigate how per- and polyfluoroalkyl substances (PFAS) adsorb onto polypropylene nanoplastics in aquatic environments. They found that the adsorption is primarily driven by dispersion forces between the PFAS fluorinated chains and the plastic polymer, with the nanoplastic flexing locally to maximize contact with the contaminant molecules. The study suggests that polypropylene nanoplastics can effectively carry a range of PFAS compounds, potentially increasing their bioaccumulation in organisms during co-exposure.

Adsorption of PFAS onto secondary microplastics: A mechanistic study
Researchers studied how PFAS (toxic "forever chemicals") attach to microplastics that form when PET water bottles break down in the environment. They found that PFAS bonds to these microplastic surfaces within hours in both fresh and salt water, meaning microplastics can act as carriers for these harmful chemicals. This is concerning because people may be exposed to both microplastics and the dangerous chemicals hitchhiking on them through contaminated water.
Molecular-Scale Insights into the Interactions between Perfluoroalkyl Substances and Polyethylene
Scientists found that tiny plastic particles called microplastics can strongly attract and hold onto toxic "forever chemicals" called PFAS, which are already found in drinking water and food. This means microplastics in our environment could act like sponges that collect these harmful chemicals and potentially transport them to new places, including into our bodies. The research helps explain why these two types of pollution might work together to create bigger health risks than either one alone.

The study highlights that the combination of these two widespread pollutant types may pose greater ecological risks than either one alone.
Microplastics and PFAS air-water interaction and deposition
This study examines how microplastics and PFAS (forever chemicals) interact in the environment, with microplastics acting as carriers that transport PFAS through water and air over long distances. Both pollutants are persistent and can deposit together in urban, rural, and remote areas through rain and atmospheric fallout. The combined exposure to both microplastics and PFAS is a growing concern for human health because their toxic effects may be amplified when they occur together.

Adsorption of perfluoroalkyl substances on polyamide microplastics: Effect of sorbent and influence of environmental factors
Researchers studied how perfluoroalkyl substances (PFAS), a group of persistent industrial chemicals, bind to polyamide microplastics in water. They found that smaller microplastic particles absorbed dramatically more PFAS than larger ones, and that water chemistry conditions like pH and salinity influenced the process. The findings suggest microplastics can concentrate harmful chemicals and potentially increase human and wildlife exposure to PFAS in contaminated environments.
Uptake and release of perfluoroalkyl carboxylic acids (PFCAs) from macro and microplastics
Researchers studied how perfluoroalkyl carboxylic acids, a class of persistent PFAS chemicals, interact with both macro and microplastics in aquatic environments. They found that microplastics can adsorb and later release these harmful chemicals, with the interaction influenced by the amphiphilic properties of the contaminants. The findings suggest that microplastics may serve as carriers for PFAS contamination, potentially increasing exposure pathways for organisms in the environment.

This study tested how PFAS ("forever chemicals") interact with 18 different types of microplastic and found that polyamide (nylon) plastics absorbed up to 100% of the PFAS in solution. Since both PFAS and microplastics are widespread environmental pollutants, their ability to bind together means microplastics may act as carriers that concentrate and transport these harmful chemicals into water, soil, and ultimately the human body.
