ClearFate of microplastics and emerging contaminants: Mechanisms of interactions, bioaccumulation and combined toxicity to aquatic organisms
This review summarizes how microplastics interact with other emerging contaminants in water, finding that microplastics can absorb pollutants at concentrations up to a million times higher than surrounding water and carry them into living organisms. The combined toxicity of microplastics plus these hitchhiking chemicals is often greater than either alone, and these pollutants can reach humans through the food chain.
Ecotoxicological effects of microplastics and adsorbed contaminants on aquatic organisms
This review summarizes ecotoxicological studies on microplastics and their adsorbed contaminants in microalgae, crustaceans, mollusks, and fish. Across all tested organisms, microplastics caused growth inhibition, reduced reproduction, and physiological stress — particularly when carrying additional chemical contaminants.
[Research Progress on Trojan-horse Effect of Microplastics and Heavy Metals in Freshwater Environment].
This review examines the Trojan-horse effect in freshwater environments where microplastics adsorb and transport heavy metals, significantly increasing their potential ecological harm due to the large surface area and persistence of microplastic particles.
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.
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.
Microplastic-Toxic Chemical Interaction: A Review Study on Quantified Levels, Mechanism and Implication
This review summarizes quantified levels of heavy metals and hydrophobic organic contaminants sorbed onto microplastics in environmental media, examining adsorption and desorption mechanisms and discussing health implications of ingested microplastics acting as vectors for toxic chemical transport.
Interaction of Environmental Pollutants with Microplastics: A Critical Review of Sorption Factors, Bioaccumulation and Ecotoxicological Effects
This critical review examines how microplastics interact with and enhance the toxicity of co-occurring environmental pollutants including heavy metals, persistent organic compounds, and pharmaceuticals, synthesizing evidence on sorption mechanisms and combined ecotoxicological effects.
The bioaccumulation effects of microplastics and associated organic pollutants in the aquatic environment
This review examined how microplastics in aquatic environments interact with organic pollutants through adsorption, affecting the bioaccumulation and toxicity of those pollutants in aquatic organisms due to the high hydrophobicity of microplastic 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.
Adsorption of Pollutants on Microplastics in Freshwater
This book chapter examines adsorption of co-contaminants—including heavy metals, pesticides, and pharmaceuticals—onto microplastic surfaces in freshwater environments, reviewing how plastic particle characteristics determine their capacity to concentrate and transport associated pollutants.
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.
Interaction of Chemical Contaminants with Microplastics
This review examines how chemical contaminants like heavy metals, pesticides, and pharmaceuticals adsorb onto microplastic surfaces and are transported through the environment. Microplastics act as vectors that concentrate and move toxic chemicals, potentially amplifying human exposure through food and water.
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.
Microplastics as Vectors of Chemicals and Microorganisms in the Environment
This review examines microplastics as vectors for chemicals and microorganisms in the environment, discussing the 'plastisphere' concept, hydrophobic surface interactions that facilitate pollutant adsorption, biofilm formation, and the mechanisms by which microplastics transport contaminants and pathogens through aquatic systems.
Adsorption behaviors of atrazine and imidacloprid on high temperature aged microplastics: Mechanism and influencing factors
Researchers investigated how aged polyethylene microplastics — the kind that have been weathered by UV light and heat in the environment — adsorb common agricultural pesticides, finding that microplastics can accumulate pesticides like atrazine and imidacloprid at high concentrations through hydrophobic (water-avoiding) interactions. This "Trojan horse" effect means microplastics can carry and potentially concentrate pesticides as they move through water environments.
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.
Microplastics with adsorbed contaminants: Mechanisms and Treatment
This review examines how microplastics adsorb environmental contaminants including heavy metals, organic pollutants, and pathogens, and surveys treatment methods for removing contaminated microplastics from water. Researchers found that microplastics can act as vectors for hazardous substances, potentially increasing their bioavailability and toxicity in aquatic ecosystems. The study evaluates emerging remediation technologies and highlights the complex environmental risks posed by microplastics carrying adsorbed pollutants.
Microplastics as vectors for environmental contaminants: Exploring sorption, desorption, and transfer to biota
This review explores how microplastics interact with hydrophobic organic chemicals in aquatic environments, examining the processes of chemical sorption onto and desorption from plastic particles. Researchers discuss the factors that influence whether microplastics act as significant carriers of environmental contaminants into living organisms compared to natural pathways. Understanding these processes is essential for accurately assessing the real-world risk that microplastics pose as chemical transport vehicles.
Adsorption of heavy metals by biofilm-coated microplastics in aquatic environments: Mechanisms, isotherm and kinetic processes, and influencing factors
This review synthesizes research on how biofilms—microbial coatings that naturally form on microplastics in water—alter the particles' ability to absorb heavy metals like lead, copper, and cadmium, finding that biofilmed microplastics generally adsorb more metal than bare plastic and that electrostatic forces and surface complexation are the dominant mechanisms. This matters because microplastics coated in both biofilm and toxic metals may deliver a double dose of contamination to organisms that ingest them. The review identifies key gaps, including how competitive metal mixtures and shifting biofilm composition over time affect this combined pollution risk.
The impact of microplastic pollution on ecological environment: a review
This review examines the broad ecological impact of microplastic pollution, focusing on how the strong adsorption capacity of microplastic surfaces allows them to carry persistent organic pollutants through the environment. Researchers found that the combined effects of microplastics and adsorbed chemicals increase toxicity to organisms across different levels of the food chain. The study calls for more research into the long-term ecological consequences of microplastic pollution and its synergistic effects with other contaminants.
