ClearAdsorption 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.
Investigation of interfacial adsorption between microplastics and methylparaben in aqueous solution
Researchers investigated the adsorption of methylparaben — a common preservative — onto polystyrene, polyethylene, PET, and PVC microplastics in aqueous solution, finding that adsorption capacity varied by polymer type and was influenced by pH and ionic strength, with implications for paraben transport in aquatic environments.
Microplastics as potential bisphenol carriers: role of adsorbents, adsorbates, and environmental factors
Laboratory experiments showed that four common microplastic types — polystyrene, polypropylene, polyamide, and PVC — all readily adsorb bisphenols (BPA, BPB, BPF, BPS), with polyamide showing the highest capacity. Adsorption was strongly influenced by polymer surface chemistry, bisphenol hydrophobicity, temperature, and salinity. Because bisphenols are potent endocrine disruptors, microplastics acting as their environmental carriers could amplify human and wildlife exposure through contaminated seafood and drinking water.
Effects of nanoplastics and microplastics on the availability of pharmaceuticals and personal care products in aqueous environment
Researchers found that nanoplastics and microplastics can sorb pharmaceuticals and personal care products in water, with smaller nanoplastics showing 1-2 orders of magnitude stronger sorption than microplastics, potentially reducing the bioavailability of these contaminants in aquatic environments.
Microplastic sorption of personal care products in aquatic environments: mechanisms and key factors
This review of existing research shows that tiny plastic particles in water can absorb and carry chemicals from personal care products like sunscreen, soap, and cosmetics. When microplastics pick up these chemicals, they could potentially transport them to new places in the environment and possibly into our food chain. This matters because it suggests microplastics might be spreading personal care chemicals in ways we don't fully understand yet.
Sorption of alkylphenols and estrogens on microplastics in marine conditions
Researchers investigated the sorption of six endocrine-disrupting chemicals — including alkylphenols and estrogens — onto microplastics under marine conditions, supporting the hypothesis that microplastics act as a secondary contamination vector for aquatic organisms by concentrating pollutants.
Modified Cellulose for Adsorption of Methylparaben and Butylparaben from an Aqueous Solution
Researchers developed modified cellulose materials to remove parabens, common preservatives used in cosmetics and food that act as hormone disruptors, from water. While not directly about microplastics, this work is relevant because both parabens and microplastics are emerging water contaminants that affect human health. Better water purification methods that can remove a range of these pollutants could reduce overall exposure to harmful chemicals.
Adsorption behavior and interaction mechanism of microplastics with typical hydrophilic pharmaceuticals and personal care products
This study examined how different types of microplastics adsorb hydrophilic pharmaceuticals and personal care products (PPCPs) in aquatic environments, finding that polymer type and surface properties governed the interaction mechanisms. The results indicate that microplastics can act as vectors for these emerging contaminants.
Mechanistic insights into the adsorption of endocrine disruptors onto polystyrene microplastics in water
Researchers studied the mechanisms by which polystyrene microplastics adsorb endocrine-disrupting compounds from aquatic environments, finding that hydrophobic interactions and surface chemistry govern the binding. The results clarify how microplastics act as vectors for co-transporting endocrine disruptors through aquatic ecosystems.
Interactions between microplastics, pharmaceuticals and personal care products: Implications for vector transport
This review examines how microplastics can absorb pharmaceuticals and personal care products (like medications, sunscreen, and antibacterials) onto their surfaces in the environment. Environmental factors like water acidity, salt levels, and organic matter all affect how strongly these chemicals bind to plastic surfaces. When organisms ingest microplastics carrying these absorbed chemicals, the combined exposure could pose greater health risks than either the plastics or chemicals alone.
Adsorption behaviour and interaction of organic micropollutants with nano and microplastics – A review
This review analyzed the adsorption behavior of organic micropollutants — including pharmaceuticals, pesticides, and industrial chemicals — onto nano- and microplastics, finding that adsorption is governed by pollutant hydrophobicity, particle surface area, and aging state, and that microplastics can act as vectors delivering co-contaminants to aquatic organisms.
Implications of polystyrene and polyamide microplastics in the adsorption of sulfonamide antibiotics and their metabolites in water matrices
Researchers found that polystyrene and polyamide microplastics can absorb sulfonamide antibiotics from water, with smaller particles and acidic conditions increasing absorption significantly. This means microplastics in the environment can act as carriers for antibiotics, potentially spreading antimicrobial resistance. The finding raises concerns because people may be exposed to both microplastics and the drugs they carry through contaminated water and food.

Understanding these processes is essential for accurately assessing the real-world risk that microplastics pose as chemical transport vehicles.
Microplastics meet micropollutants in a central european river stream: Adsorption of pollutants to microplastics under environmentally relevant conditions
Researchers investigated how microplastics adsorb organic micropollutants in a Central European river under real-world conditions. They found that aged microplastics showed higher adsorption capacity for contaminants compared to pristine ones, and that the type of plastic material influenced which pollutants were absorbed. The findings suggest that microplastics in rivers can act as carriers for harmful chemicals, potentially spreading contamination through aquatic ecosystems.
Adsorption of Macrolide Antibiotics and a Metabolite onto Polyethylene Terephthalate and Polyethylene Microplastics in Aquatic Environments
Researchers studied how four macrolide antibiotics and a metabolite adsorb onto polyethylene terephthalate and polyethylene microplastics in water. They found that antibiotic adsorption followed a linear model, with PET showing higher adsorption capacity than polyethylene. The study suggests that microplastics in aquatic environments may serve as carriers for antibiotics, potentially affecting how these pharmaceutical pollutants are distributed in water systems.
Sorption and dissipation of current-use pesticides and personal-care products on high-density polyethylene microplastics in seawater
Researchers characterized how three pesticides and three personal care products sorb onto high-density polyethylene microplastics in seawater. They found that more hydrophobic compounds accumulated more readily on the plastic, and that significant desorption (over 30%) occurred within 24 hours, especially at higher contaminant concentrations. The study confirms that microplastics can act as both carriers and releasers of chemical pollutants in marine environments.
