ClearInteractions 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.
Microplastic–Pharmaceuticals Interaction in Water Systems
This review examined the interactions between microplastics and pharmaceutical compounds in aquatic environments, exploring how microplastics act as vectors that concentrate, transport, and potentially enhance the bioavailability and toxicity of drug residues in water.
Pharmaceuticals and micro(nano)plastics in the environment: Sorption and analytical challenges
This review examines how pharmaceutical residues and micro- and nanoplastics interact in water environments, finding that microplastics can adsorb medications and alter their environmental behavior. Factors like plastic type, surface area, and biological film growth all influence these interactions, but very few studies have been conducted under real-world conditions. The authors highlight persistent analytical challenges and the need for field-based research to understand actual risks.
Adsorption behavior of organic pollutants and metals on micro/nanoplastics in the aquatic environment
This review examines how micro- and nanoplastics in aquatic environments adsorb organic pollutants and metals onto their surfaces, effectively acting as carriers for other contaminants. Researchers found that environmental factors like pH, salinity, and aging of the plastic significantly influence this sorption behavior. The findings raise concerns that microplastics may increase the bioavailability and toxicity of chemical pollutants in waterways.
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 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.
Microplastics Meet Metoprolol in Natural Water: Sorption Behavior and Mechanism
Laboratory experiments showed that common plastic types — polyvinyl chloride and polypropylene — readily adsorb the heart medication metoprolol from water, and that this adsorption increases at higher pH and in the presence of dissolved organic matter (humic acids). These findings raise concern that microplastics in aquatic environments could act as transport vectors for pharmaceutical drugs, potentially delivering them to fish and other organisms in concentrated doses.
Interactions between microplastics and organic compounds in aquatic environments: A mini review
Researchers reviewed the mechanisms of interaction between microplastics and organic compounds in aquatic environments, examining factors related to the plastics themselves, the organic compounds, and environmental conditions. The study found that properties like crystallinity, surface area, and weathering state of microplastics all influence how they adsorb and transport organic pollutants, with implications for environmental and health risk assessments.
Adsorption 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.
Microplastics as vectors of pharmaceuticals in aquatic organisms – An overview of their environmental implications
Researchers reviewed how microplastics act as "vectors" for pharmaceutical contaminants in aquatic environments, absorbing drugs onto their surfaces and then releasing them inside organisms after ingestion — potentially amplifying the toxicity of pharmaceuticals throughout the food web.
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.
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.
Sorption of Pharmaceuticals on Microplastics
This review examines the sorption of pharmaceuticals onto microplastics in aquatic environments, analyzing how polymer type, particle size, surface area, polarity, and pharmaceutical properties such as log Kow and pKa influence sorption behavior, and how weathering and aging processes increase sorption capacity by altering microplastic surface chemistry and topography.
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.
Micro(nano)plastics as a vector of pharmaceuticals in aquatic ecosystem: Historical review and future trends
This systematic review examines how microplastics and nanoplastics in water can absorb and carry pharmaceutical drugs, creating a combined pollution threat. When medications attach to tiny plastic particles in rivers and oceans, they may become more harmful to aquatic life and potentially to humans who consume contaminated seafood or water. The research traces how this emerging double-threat has grown since 2018 and identifies key knowledge gaps.

Adsorption behaviour and interaction of organic micropollutants with nano and microplastics – A review
This review analyzed the adsorption behavior of organic micropollutants — including pharmaceuticals, pesticides, and industrial chemicals — onto nano- and microplastics, finding that adsorption is governed by pollutant hydrophobicity, particle surface area, and aging state, and that microplastics can act as vectors delivering co-contaminants to aquatic organisms.
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.
