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.
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.
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.
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.
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.
Physisorption and Chemisorption Mechanisms Influencing Micro (Nano) Plastics-Organic Chemical Contaminants Interactions: A Review
This review explains the chemical and physical mechanisms by which microplastics attract and carry organic pollutants like pesticides, pharmaceuticals, and industrial chemicals in the environment. The ability of microplastics to absorb these contaminants depends on factors like plastic type, particle size, weathering, and water conditions. Understanding these interactions is critical because when contaminated microplastics are ingested by organisms or humans, the absorbed chemicals can be released inside the body.
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.
Uptake/release of organic contaminants by microplastics: A critical review of influencing factors, mechanistic modeling, and thermodynamic prediction methods
This review critically examines the ability of microplastics to absorb and release organic chemical pollutants, evaluating the factors that influence this process and existing predictive models.

This review critically examines how chemical contaminants like persistent organic pollutants and heavy metals sorb onto microplastic surfaces in the environment.
