The interaction mechanism of polystyrene microplastics with pharmaceuticals and personal care products
Computational chemistry methods including force field and density functional theory calculations were used to characterize how polystyrene microplastics interact with co-occurring pharmaceuticals and other organic water pollutants, revealing hydrophobic and pi-pi stacking interactions as dominant adsorption mechanisms.

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.

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.

The study suggests that microplastics in aquatic environments can concentrate harmful PFAS compounds, potentially increasing exposure for organisms that ingest them.
