ClearSorption kinetics, isotherms and molecular dynamics simulation of 17β-estradiol onto microplastics
Researchers investigated the adsorption of the endocrine disruptor 17-beta-estradiol onto three common microplastics using kinetic experiments and molecular dynamics simulations, finding that hydrophobic interactions drive sorption and that polymer type significantly influences adsorption capacity.
Interfacial sorption of 17β-E2 on nano-microplastics: Effects of particle size, functional groups and hydrochemical conditions
This study examined how nanoscale polystyrene particles — a form of nanoplastic — bind to 17β-estradiol, a natural estrogen that is also an emerging environmental contaminant. Smaller particles adsorbed more of the hormone due to their larger surface area, and surface chemistry played a key role: hydrophobic (water-repelling) surfaces bound more estrogen than particles modified with polar chemical groups. The findings suggest that nanoplastics in water bodies could act as vectors, concentrating and transporting hormones to fish and other aquatic life, potentially amplifying endocrine disruption.

[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.

Researchers investigated how the presence of microplastics in soil affects the adsorption behavior of the hormone 17-beta-estradiol. The study found that common greenhouse soil microplastics including polyethylene, polyvinyl chloride, and polystyrene influenced how estrogen compounds bind to soil, suggesting that microplastic contamination may alter the environmental fate of hormonal pollutants.
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.

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.
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.
Bioavailability of steroid hormones sorbed on microplastics for aquatic organisms through biological fluids
This study examined how steroid hormones adsorbed to microplastics in water can desorb under simulated digestive conditions in aquatic organisms.
