Studies on competitive adsorption characteristics of bisphenol A and 17α-ethinylestradiol on thermoplastic polyurethane by site energy distribution theory
This study examined how two common endocrine-disrupting chemicals — bisphenol A (BPA) and the synthetic hormone 17α-ethinylestradiol (EE2) — adsorb onto thermoplastic polyurethane microplastics in both single and mixed solutions, finding that BPA and EE2 compete for adsorption sites in ways that alter each compound's uptake. The findings matter because microplastics act as carriers for hazardous chemicals, and understanding competitive adsorption helps predict how contaminated plastics transport hormone-disrupting pollutants through aquatic environments.

Sorption and bioacessibility of 17β-Estradiol on Environmental Microplastics: Particle Size, Aging, Competitive Interactions and Co-exposure
This study investigated the sorption of the hormone 17β-estradiol onto polyethylene terephthalate and polyethylene microplastics, examining how particle size and aging affect sorption capacity and co-exposure toxicity. Smaller and aged MPs showed higher estrogen sorption, increasing the potential for MPs to act as vectors for hormonal contaminants in aquatic environments.
Influence of microplastics occurrence on the adsorption of 17β-estradiol in soil
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.
Effects of microplastic interaction with persistent organic pollutants on the activity of the aryl hydrocarbon and estrogen receptors
This study investigated how microplastics carrying absorbed chemical pollutants affect hormone-related receptors in human cells. The researchers found that pollutants attached to microplastic surfaces could activate estrogen receptors and interfere with normal hormone signaling. This suggests that microplastics may act as delivery vehicles for endocrine-disrupting chemicals, potentially contributing to hormone-related health problems in people.
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. The findings suggest that microplastics can serve as carriers delivering hormone-disrupting chemicals to organisms that ingest them, with potential implications for reproductive health in aquatic wildlife.
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.
Interactions between microplastics and phthalate esters as affected by microplastics characteristics and solution chemistry
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.
The Material Matters: Sorption/Desorption Study of Selected Estrogens on Common Tubing or Sampling Materials Used in Water Sampling, Handling, Analysis or Treatment Technologies
Researchers tested whether common plastic and rubber tubing and sampling materials used in water treatment and analysis adsorb estrogen compounds from water samples.

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.
Microplastics in the environment: analytical chemistry methods, sorption materials, risks and sustainable solutions
This review covers the full picture of microplastic pollution, from how scientists detect and measure these particles to how they carry other pollutants and affect living organisms. The authors highlight that microplastics act as tiny sponges that absorb harmful chemicals like pharmaceuticals and pesticides, then release them inside organisms that ingest the particles. The review calls for more standardized testing methods and sustainable solutions to reduce both microplastic pollution and its risks to human health.
