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.
Interactions between microplastics and organic compounds in aquatic environments: A mini review
Researchers reviewed the mechanisms of interaction between microplastics and organic compounds in aquatic environments, examining factors related to the plastics themselves, the organic compounds, and environmental conditions. The study found that properties like crystallinity, surface area, and weathering state of microplastics all influence how they adsorb and transport organic pollutants, with implications for environmental and health risk assessments.
Adsorption behavior of organic pollutants on microplastics
This review summarizes the main mechanisms by which microplastics adsorb organic pollutants, including hydrophobic interactions, electrostatic forces, and hydrogen bonding. Researchers found that particle size, surface area, aging, and environmental factors like pH and temperature significantly influence how much pollution microplastics can carry. The study highlights the need for more field-based research to understand how microplastics behave as pollutant carriers in real environmental conditions.
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.
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.
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.
Review on microplastic-polymer composite interactions: assessing contaminant adsorption, structural integrity, and environmental impacts
This review examined how microplastics interact with polymer composites and serve as carriers for heavy metals, organic pollutants, and pathogens. The study assessed how polymer type, surface properties, and environmental conditions influence contaminant adsorption and transport, highlighting the complex role of microplastics in pollutant cycling.
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.
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.
Interakcije mikroplastike i organskih onečišćivala u vodi
This Croatian-language review covers how microplastics adsorb and transport organic contaminants in water, examining the adsorption mechanisms (hydrophobic partitioning, surface interactions), factors affecting uptake capacity (polymer type, aging, particle size), and how co-contamination may amplify overall toxicity.
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.
The chemical behaviors of microplastics in marine environment: A review
This review summarized interactions between microplastics and organic pollutants and metals in the marine environment, covering sorption behavior across polymer types, the role of degradation in altering sorption capacity, and global monitoring data on pollutant concentrations on marine plastics. The authors conclude that microplastic type, pollutant properties, and environmental conditions all strongly influence chemical accumulation on plastic surfaces.
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. Researchers found that while microplastics can concentrate pollutants at levels far above surrounding water, the actual contribution of microplastics to contaminant transfer into organisms may be less significant than direct exposure from water and food. The study calls for more realistic experimental designs to clarify the true risk.
Interactions of microplastics with organic, inorganic and bio-pollutants and the ecotoxicological effects on terrestrial and aquatic organisms
This review systematically examines how microplastics interact with organic pollutants, heavy metals, and biological contaminants in the environment. Researchers found that microplastics can adsorb and transport these pollutants, creating complex combinations that may be more toxic to organisms than either pollutant alone. The study highlights the risks these interactions pose to both ecosystem health and human well-being.
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.

This state-of-the-science review examined whether microplastics serve as vectors for bioaccumulation of hydrophobic organic chemicals in marine organisms.

Adsorption of organic pollutants by microplastics: Overview of a dissonant literature
This review critically examines the scientific literature on how microplastics adsorb organic pollutants in aquatic environments. Researchers found significant inconsistencies across studies regarding the mechanisms and extent of pollutant uptake by microplastics, noting that factors like particle size, polymer type, and environmental conditions all play important roles.

This review examines how microplastics interact with persistent organic pollutants in the environment, including how factors like salinity, pH, and plastic type affect the sorption of toxic chemicals onto microplastic surfaces.
