ClearMicroplastics 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.
Relative importance of microplastics as a pathway for the transfer of hydrophobic organic chemicals to marine life
Researchers assessed the relative importance of microplastics as a pathway for transferring hydrophobic organic chemicals to marine life. The study suggests that while microplastics can carry high concentrations of contaminants, factors like gut surfactants, pH, and temperature influence desorption rates, and modeling indicates other exposure routes may be more significant in natural environments.
Vector effects of microplastics on organic pollutants: sorption-desorption and bioaccumulation kinetics
This review synthesizes existing research on whether microplastics act as carriers that increase the bioaccumulation of organic pollutants in aquatic organisms. Researchers found evidence that microplastics can adsorb hydrophobic pollutants from water and release them in the gut of organisms that ingest them, potentially enhancing toxic effects. 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.

This review examines the dual role of microplastics in the marine environment as both accumulators of persistent organic pollutants and vectors that transport these chemicals and other contaminants including heavy metals, pharmaceuticals, and pathogens.

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.
Microplastics as a vector of hydrophobic contaminants: Importance of hydrophobic additives
This paper examines the role of hydrophobicity in determining whether organic pollutants sorbed to microplastics pose a meaningful additional risk beyond direct water exposure. The authors argue that for most scenarios, the contribution of microplastics to total pollutant exposure is smaller than commonly assumed and depends heavily on the properties of the specific chemical and polymer.

This paper discusses how microplastics released into the sea environment accumulate organic pollutants and increase their concentration relative to the surrounding water, amplifying exposure risks for marine life. The review highlights microplastics as vectors that concentrate and transport toxic chemicals through marine food webs.
Microplastic properties and their interaction with hydrophobic organic contaminants: a review
This review examines the physical and chemical properties of microplastics that determine how they interact with hydrophobic organic contaminants in the environment. Researchers found that factors like polymer type, particle size, weathering, and surface chemistry all influence how strongly microplastics bind to co-occurring pollutants. The findings suggest that microplastics can serve as carriers for harmful chemicals, potentially increasing exposure risks for organisms that ingest them.
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.

Partitioning of chemical contaminants to microplastics: Sorption mechanisms, environmental distribution and effects on toxicity and bioaccumulation
This review critically examines how chemical contaminants like persistent organic pollutants and heavy metals sorb onto microplastic surfaces in the environment.

The study calls for more realistic experimental designs to clarify the true risk.
