ClearInteractions 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.
Trophic transfer and interfacial impacts of micro(nano)plastics and per-and polyfluoroalkyl substances in the environment.

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.

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.
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.

Researchers collected microplastics from eight rivers in the Pearl River Estuary region of China across seasons and measured concentrations of poly- and perfluoroalkyl substances (PFAS) on their surfaces, finding that MP-bound PFAS concentrations varied by season and river and that MPs may be an overlooked pathway for PFAS transport in aquatic systems.
The unheeded inherent connections and overlap between microplastics and poly- and perfluoroalkyl substances: A comprehensive review
This review reveals the overlooked connection between microplastics and PFAS (forever chemicals), showing that these two widespread pollutants often come from the same products and interact in the environment. Microplastics can absorb PFAS onto their surfaces and transport them through water systems, potentially increasing exposure for aquatic organisms and humans. Understanding this overlap is important because the combined effects may be more harmful than either pollutant alone.
Poly- and Perfluoroalkyl Substances (PFAS): Do They Matter to Aquatic Ecosystems?
This review examines PFAS, the persistent 'forever chemicals' widely used in consumer products, and their growing threat to aquatic ecosystems. Evidence indicates that PFAS accumulate in aquatic organisms, disrupt hormones, and can alter how other pollutants behave in the environment. The research is relevant to microplastic concerns because PFAS are commonly found in plastic products and can leach from microplastics into water.

Researchers investigated interactions between polystyrene microplastics and the PFAS compound undecafluorohexanoic acid in aquatic systems, finding that microplastics can serve as adsorption and transport media for PFAS, with implications for their combined environmental impact.
Adsorption of perfluoroalkyl substances on microplastics under environmental conditions
Researchers examined the capacity of three types of microplastics to sorb 18 perfluoroalkyl substances from freshwater and seawater. They found that perfluorosulfonates and sulfonamides had the strongest tendency to adsorb onto microplastics, with polystyrene showing greater affinity for these chemicals than polyethylene. The study suggests that microplastics in aquatic environments can concentrate harmful PFAS compounds, potentially increasing exposure for organisms that ingest them.

Researchers studied how microplastics in food affect the body's absorption of per- and polyfluoroalkyl substances (PFAS), a class of persistent chemicals found in drinking water. They found that high doses of polystyrene microplastics significantly increased PFAS absorption in mice while reducing the amount excreted, essentially making these harmful chemicals more bioavailable. The study suggests that microplastics in the diet could amplify the health risks posed by co-occurring chemical contaminants.
Combined Environmental Impacts and Toxicological Interactions of Per- and Polyfluoroalkyl Substances (PFAS) and Microplastics (MPs)
This review examines how microplastics and per- and polyfluoroalkyl substances (PFAS) frequently co-occur in the environment and interact to alter each other's environmental fate and biological effects. Researchers found that co-exposure can enhance PFAS bioaccumulation by up to 2.5-fold compared to PFAS alone, accompanied by amplified oxidative stress, immune disruption, and reproductive impairment in aquatic organisms. The magnitude and direction of combined effects depend heavily on polymer type, particle size, surface aging, and biological context.
