ClearMicroplastics meet micropollutants in a central european river stream: Adsorption of pollutants to microplastics under environmentally relevant conditions
Researchers investigated how microplastics adsorb organic micropollutants in a Central European river under real-world conditions. They found that aged microplastics showed higher adsorption capacity for contaminants compared to pristine ones, and that the type of plastic material influenced which pollutants were absorbed. The findings suggest that microplastics in rivers can act as carriers for harmful chemicals, potentially spreading contamination through aquatic ecosystems.
A systematic review of microplastics in the environment: Sampling, separation, characterization and coexistence mechanisms with pollutants
Massive microplastic pollution was documented across Africa, Asia, India, South Africa, North America, and Europe, with MPs acting as carriers of heavy metals that enter organisms and cause harm. The adsorption capacity of organic pollutants onto microplastics correlated with hydrophobicity, surface area, and functional group characteristics.
Transport of persistent organic pollutants: Another effect of microplastic pollution?
This review examines how microplastics act as vectors for persistent organic pollutants (POPs) in aquatic environments, covering the physical and chemical factors governing pollutant adsorption and desorption. The authors discuss how interactions between microplastics and POPs vary with polymer type, particle properties, and environmental conditions, and when these interactions may result in toxic effects on aquatic organisms.
Microplastics as vectors of chemical contaminants and biological agents in freshwater ecosystems: Current knowledge status and future perspectives
This review examines how microplastics in freshwater ecosystems act as carriers for chemical pollutants and harmful microorganisms. Researchers found that pollutant concentrations on microplastic surfaces can be up to six times higher than in surrounding water, amplifying exposure risks for aquatic life and potentially humans. The findings highlight that microplastics are not just a pollution problem themselves but also a vehicle that spreads other contaminants through the food web.
Microplastic pollution in aquatic environments in Africa: status and research opportunities
This review examines the status of microplastic pollution research in African aquatic environments, noting that Africa's high rate of plastic waste mismanagement has resulted in widespread contamination of freshwater and marine ecosystems. Researchers found significant research gaps in the region despite its outsized contribution to global plastic pollution, and identified opportunities for expanded monitoring given microplastics' capacity to adsorb persistent organic pollutants.
Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants
This review summarizes how microplastics in the environment interact with organic pollutants—adsorbing, carrying, and releasing them. Microplastics act as mobile carriers for persistent organic chemicals, altering their distribution and toxicity in ecosystems and the organisms, including humans, that consume them.
Micro(nano)plastics: Unignorable vectors for organisms
This review examines the role of micro- and nanoplastics as vectors for contaminants — including heavy metals, organic pollutants, and pathogens — in aquatic and terrestrial environments. It synthesizes evidence on how plastic particles can adsorb, transport, and release harmful substances, amplifying their ecological and health risks beyond the physical effects of the particles alone.
Microplastics as vectors of contaminants
This review highlights the emerging role of microplastics as carriers of biological and chemical contaminants in water environments. Researchers note that while microplastic pollution is increasingly well-documented, the interactions between contaminants adsorbed onto microplastic surfaces and aquatic organisms remain poorly understood. The study stresses the need for further investigation into how microplastics may facilitate the transport and bioavailability of pollutants.
Do microplastics mediate the effects of chemicals on aquatic organisms?
This review examined whether microplastics act as vectors for chemical contaminants in aquatic organisms, finding that while chemicals can sorb to microplastics, the evidence for microplastics significantly enhancing chemical toxicity in natural settings remains limited.
Microplastics in river water: occurrence, weathering, and adsorption behaviour
Researchers examined microplastics in river water, characterizing their occurrence, degree of weathering, and capacity to adsorb co-contaminants. The study highlights microplastics as vectors that can transport and re-release other pollutants in freshwater systems.
Microplastics as vectors of organic pollutants in aquatic environment: A review on mechanisms, numerical models, and influencing factors
This review examines how microplastics act as carriers for organic pollutants in water, adsorbing chemicals like pesticides and pharmaceuticals onto their surfaces and transporting them through aquatic environments. Researchers analyzed the mechanisms behind this process, including hydrophobic interactions and surface adsorption, along with the mathematical models used to predict pollutant uptake. The study highlights that microplastics may amplify the environmental impact of other contaminants by concentrating and redistributing them.
Influence of microplastics on nutrients and metal concentrations in river sediments
Researchers investigated how microplastics influence nutrient and metal concentrations in river sediments, finding that microplastics alter the distribution of pollutants through their capacity to adsorb contaminants and support biofilm formation on their hydrophobic surfaces.
Trojan horse effects of microplastics: A mini-review about their role as a vector of organic and inorganic compounds in several matrices
This review examines the 'Trojan horse' role of microplastics as vectors for organic and inorganic pollutants, finding that adsorption follows Freundlich models and that contaminant transfer to organisms is species-specific, with some species showing increased and others decreased toxicant bioavailability.

Researchers measured microplastic concentrations and polychlorinated biphenyl (PCB) levels at six sites along the urbanized Langat River in Malaysia, finding microplastics acting as vectors that adsorb and transport PCBs with concentrations highest at sites with the greatest industrial activity.
Microplastics as carriers of toxic pollutants: Source, transport, and toxicological effects
This review summarizes how microplastics absorb and carry toxic pollutants like persistent organic pollutants, heavy metals, and antibiotics through the environment, concentrating these harmful chemicals as they move through ecosystems. When organisms ingest these contaminated particles, the pollutants can build up in the food chain and eventually reach humans, making microplastics not just a physical hazard but also a chemical delivery system.

The study acknowledges the ongoing debate between vector and no-vector perspectives and outlines a consensus based on the available sorption, desorption, and bioaccumulation data.
