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.
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.
Sorption of endocrine disrupting compounds onto polyamide microplastics under different environmental conditions: Behaviour and mechanism
Polyamide microplastics sorbed the synthetic estrogens EE2, E2, and estriol with affinity influenced by pH, ionic strength, and temperature, with sorption capacity decreasing under alkaline conditions that mimic some aquatic environments, suggesting that water chemistry governs how effectively polyamide MPs concentrate endocrine-disrupting compounds.

[Sorption Characteristics and Site Energy Distribution Theory of Typical Estrogens on Microplastics].
This study examined how polyethylene microplastics adsorb six types of estrogens — hormones that can disrupt reproduction and development in animals and humans. Researchers found that PE microplastics readily bind multiple estrogens, with adsorption behavior depending on estrogen structure and water chemistry. These findings confirm that microplastics can act as carriers for hormone-disrupting chemicals in the environment.

The sorption of two phthalate esters onto polystyrene, polyethylene, and polypropylene microplastics was studied under varying conditions, finding that sorption was influenced by polymer type, phthalate structure, temperature, salinity, and dissolved organic matter. The results provide mechanistic insight into how microplastics accumulate endocrine-disrupting phthalates from the environment.

Researchers evaluated the adsorption and desorption of the steroid hormones 17β-estradiol (E2) and 17α-ethynylestradiol (EE2) onto microplastics in seawater, finding that polymer type, particle size, salinity, pH, and humic acid concentration all influenced sorption behavior. The study provides mechanistic data relevant to assessing microplastics as vectors for endocrine-disrupting compounds in marine environments.
Partitioning of chemical contaminants to microplastics: Sorption mechanisms, environmental distribution and effects on toxicity and bioaccumulation
This review critically examines how chemical contaminants like persistent organic pollutants and heavy metals sorb onto microplastic surfaces in the environment. Researchers found that while microplastics can concentrate pollutants at levels far above surrounding water, the actual contribution of microplastics to contaminant transfer into organisms may be less significant than direct exposure from water and food. The study calls for more realistic experimental designs to clarify the true risk.
Mechanistic Insights into PFAS Adsorption on Microplastics: Effects of Contaminant Properties and Water Chemistry

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.

Researchers evaluated the adsorption and desorption behavior of polychlorinated biphenyls (PCBs) onto polystyrene, polyethylene, and polyethylene terephthalate microplastics of varying sizes in marine water/sediment systems. Results showed that polymer type and particle size influenced PCB binding capacity, with microplastics acting as potential vectors for transferring persistent organic pollutants to marine biota through the food chain.
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.
The seasonality of the concentration of endocrine phenolic compounds in the matter attached to the surface of microplastics
Researchers studied how endocrine-disrupting chemicals like bisphenol A, octylphenol, and nonylphenol accumulate on microplastic surfaces in marine environments across different seasons. The study found that the biofilm and organic matter attached to microplastics concentrated these pollutants at levels 100 to 1,000 times higher than in surrounding water, with higher concentrations during warmer growing seasons. Evidence indicates that microplastics may increase organism exposure to harmful endocrine disruptors through the organic matter that colonizes their surfaces.

Smaller and aged MPs showed higher estrogen sorption, increasing the potential for MPs to act as vectors for hormonal contaminants in aquatic environments.
