ClearAdsorption 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.
Sorption of selected pharmaceutical compounds on polyethylene microplastics: Roles of pH, aging, and competitive sorption
Researchers found that polyethylene microplastics adsorb pharmaceutical compounds including an antibiotic, a beta-blocker, and an antidepressant, with sorption capacity influenced by pH, aging of the plastic, and competition between compounds — raising concern about microplastics as carriers of pharmaceuticals in aquatic environments.
Sorption of pharmaceuticals on the surface of microplastics
Researchers tested the ability of four common microplastic types to adsorb nine pharmaceutical compounds frequently found as water pollutants. They found that sorption involved both hydrophobic and electrostatic interactions, but under natural environmental conditions the binding was relatively weak. The study suggests that while microplastics can interact with pharmaceutical residues, their role as carriers of these contaminants in real aquatic environments may be more limited than previously assumed.
Unravelling the complex interactions between microplastics and PPCPs: The environment and health implications
This review examines how microplastics interact with pharmaceuticals and personal care products (PPCPs), finding that the large hydrophobic surface area of microplastics enhances PPCP adsorption, increasing their persistence, bioavailability, and potential for biomagnification through food webs.
Mechanisms of Sorption of Pharmaceutical and Personal Care Products to Microplastics

Interactive effects of micro/nanoplastics and nanomaterials/pharmaceuticals: Their ecotoxicological consequences in the aquatic systems
Researchers reviewed how micro- and nanoplastics interact with co-occurring nanomaterials and pharmaceuticals in aquatic environments, finding that plastics act as vectors that can either amplify or attenuate the bioavailability and toxicity of these contaminants depending on species, trophic level, and environmental conditions.
Mini Review on Recent Advances of the Adsorption Mechanism Between Microplastics and Emerging Contaminants for Conservation of Water
This mini-review examines the adsorption mechanisms between microplastics and emerging contaminants such as pharmaceuticals, highlighting how physicochemical properties like hydrophobicity and pH influence pollutant uptake onto different polymer types. The review synthesizes recent advances relevant to understanding how microplastics act as vectors for pharmaceutical contaminants in aquatic environments.
Sorption and desorption of selected pharmaceuticals by polyethylene microplastics
Researchers tested the sorption and desorption of three pharmaceuticals — sulfamethoxazole, propranolol, and sertraline — onto polyethylene microplastics in water, finding that all three compounds sorbed to the plastic surface and were only partially released over time. The results suggest microplastics can act as vectors for pharmaceutical compounds in aquatic environments, potentially affecting their bioavailability.
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 of a diverse range of pharmaceuticals to polyethylene microplastics in wastewater and their desorption in environmental matrices
Researchers investigated how polyethylene microplastics adsorb pharmaceuticals in municipal wastewater and release them in environmental and biological fluids. They found that drug adsorption depended heavily on the compound's charge and hydrophobicity, with cationic and hydrophobic drugs adsorbing most readily. The study suggests that microplastics could act as vectors for certain pharmaceuticals, potentially transporting them through waterways and into organisms.
