ClearMicroplastics as a vehicle of exposure to chemical contamination in freshwater systems: Current research status and way forward
This review assessed the current state of research on microplastics as vectors for chemical contaminants in freshwater systems, evaluating evidence for and against the vector hypothesis and identifying the most important knowledge gaps, including the need for studies at environmentally realistic concentrations.
Microplastics in Aquatic Systems: Dual Roles as Pollutant Carriers and Emerging Functional Materials for Water Treatment
This review examines microplastics from two angles: as carriers that absorb and transport other pollutants such as pesticides and heavy metals, and as materials that could be engineered for water treatment. The dual-role perspective is important because microplastics do not just add their own chemical burden—they also redistribute other contaminants in ways that can increase toxicity far from the original pollution source.
Vector transport of microplastics bound potentially toxic elements (PTEs) in water systems
This study examines the vector transport of microplastics carrying potentially toxic elements (PTEs) through water systems, investigating how microplastics serve as carriers that mobilise and redistribute heavy metals and other contaminants across aquatic environments.
Association of hazardous compounds with microplastics in freshwater ecosystems
This book chapter reviews how hazardous chemical compounds — including pesticides, pharmaceuticals, and heavy metals — associate with microplastics in freshwater ecosystems. Microplastics act as carriers for these compounds, potentially increasing their bioavailability to aquatic organisms and complicating risk assessment.
Nano- and microplastics in the environment : presence, effects and their role as a Trojan horse for other pollutants
This thesis reviews the presence and effects of nano- and microplastics in the environment, examining how they act as carriers for other pollutants and discussing their potential health impacts on ecosystems and humans.
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.
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.
Effects of microplastics on freshwater organisms: A laboratory approach
This thesis systematically examined how microplastics harm freshwater organisms both physically and by acting as carriers for chemical pollutants. The research found that both the physical presence of microplastics and the chemicals associated with them can negatively affect freshwater species.
Interactions of microplastics with contaminants in freshwater systems: a review of characteristics, bioaccessibility, and environmental factors affecting sorption
This review examined how microplastics act as vectors for environmental contaminants in freshwater systems, analyzing the characteristics, bioaccessibility, and environmental factors that influence pollutant sorption onto plastic particles and their potential transfer to organisms including humans.
Sorption of pesticides onto polyethylene microplastics in different aqueous matrices
This thesis examined how pesticides adsorb onto polyethylene microplastics in different aqueous matrices, finding that water chemistry significantly affects the binding behavior and potential for microplastics to carry agricultural chemicals.
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.
Effect of microplastics on the environmental behavior of emerging contaminants in aquatic matrices
This study examines how microplastics affect the environmental behavior of emerging contaminants in aquatic systems. Microplastics can adsorb other pollutants and alter their bioavailability, potentially increasing or decreasing toxic effects depending on the chemicals and environmental conditions.
Occurrence and Fate of Emerging Contaminants with Microplastics Current Scenario, Sources and Effects
This review chapter covers the current state of microplastic contamination across marine and terrestrial environments, explaining how microplastics act as vectors for other pollutants — including pharmaceuticals, pesticides, and heavy metals — that accumulate on their surfaces. These contaminant-laden particles are consumed by marine organisms and travel up the food chain, reaching human food sources. The work underscores that microplastics are not just a physical hazard but also a chemical delivery system that amplifies the toxic burden on ecosystems and people.
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 as potential vectors for selected organic chemical pollutants in river ecosystems
This study examined microplastics as vectors for organic chemical pollutants in African river ecosystems, where research on this topic remains sparse.

Degradable Microplastics as Vector of Emergent Contaminants in Wastewater: Interactions and Mechanisms of Adsorption
Degradable microplastics in wastewater can act as carriers for pesticides and other contaminants, adsorbing them from the surrounding water and potentially releasing them again in different environmental conditions such as aeration tanks. This 'Trojan horse' behavior is concerning because microplastics may transport pollutants through wastewater treatment systems that were not designed to capture these combined threats.
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.
