ClearSorption of 3,6-dibromocarbazole and 1,3,6,8-tetrabromocarbazole by microplastics
Two brominated carbazole pollutants were found to readily adsorb onto polypropylene microplastics in seawater, with smaller plastic particles absorbing more chemical per unit mass. This demonstrates that microplastics can concentrate brominated organic pollutants from seawater and potentially deliver them to marine organisms.

This study examined how halogenated polycyclic aromatic hydrocarbons (PAHs) partition between microplastics and water, finding that plastic type and contaminant chemistry both influence sorption behavior. Understanding how microplastics absorb and transport toxic chemicals is important for assessing the ecological risks they pose.
Sorption of five organic compounds by polar and nonpolar microplastics
Polar and biodegradable microplastics, including polyurethane and polycaprolactone, showed significant sorption of hydrophobic organic contaminants, with hydrogen bonding playing a greater role than for conventional nonpolar plastics. The findings extend understanding of how a wider range of plastic types can act as vectors for environmental pollutants.

Researchers systematically investigated the adsorption behavior of benzotriazoles and benzothiazoles on polyvinyl chloride microplastics in aquatic environments, characterizing adsorption kinetics, isotherms, and thermodynamics to explain the underlying mechanisms. The study revealed that PVC microplastics act as carriers for these ubiquitous water contaminants through a multilayer adsorption process, with implications for pollutant migration and ecological risk.
Effects of microplastic sorption on microbial degradation of halogenated polycyclic aromatic hydrocarbons in water
Researchers investigated how microplastics act as carriers for halogenated polycyclic aromatic hydrocarbons (HPAHs) in water and whether this sorption affects microbial degradation of these dioxin-like compounds. They found that microplastic-sorbed HPAHs had reduced bioavailability to degrading bacteria, potentially slowing natural breakdown of these toxic pollutants.
Sorption of organic compounds by microplastic
This German thesis studied how common microplastic polymers like polyethylene, polystyrene, and polyamide sorb and accumulate hydrophobic organic contaminants, investigating the mechanisms that make plastics effective carriers of pollutants. Understanding sorption behavior is key to assessing how microplastics transport toxic chemicals into marine food webs.
Sorption of Pyrene and Fluoranthene onto Common Microplastics Under Freshwater Conditions
Researchers investigated how two common polycyclic aromatic hydrocarbons, pyrene and fluoranthene, bind to six different types of microplastic polymers under freshwater conditions. The study found significant differences in sorption capacity across polymer types, confirming that microplastics can act as vectors for transporting harmful organic pollutants through aquatic environments.
Adsorption of Contaminants of Emerging Concern (CECs) with Varying Hydrophobicity on Macro- and Microplastic Polyvinyl Chloride, Polyethylene, and Polystyrene: Kinetics and Potential Mechanisms
Researchers found that both plastic size and polymer type influenced the adsorption of contaminants of emerging concern onto PVC, polyethylene, and polystyrene, with microplastics generally adsorbing more than macroplastics and contaminant hydrophobicity playing a key role in determining adsorption kinetics and capacity.
Adsorption mechanisms of chlorobenzenes and trifluralin on primary polyethylene microplastics in the aquatic environment
Researchers investigated the adsorption mechanisms of six priority chlorinated and aromatic pollutants (including trichlorobenzenes and trifluralin) onto primary polyethylene microplastics, revealing how plastic type, surface area, and compound properties govern contaminant uptake in aqueous environments.

Researchers investigated the sorption of six endocrine-disrupting chemicals — including alkylphenols and estrogens — onto microplastics under marine conditions, supporting the hypothesis that microplastics act as a secondary contamination vector for aquatic organisms by concentrating pollutants.
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.
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.
Sorption Behavior of Organic Pollutants on Biodegradable and Nondegradable Microplastics: pH Effects
This study tested how water pH affects the adsorption of chlorinated phenols, polycyclic aromatic hydrocarbons, and halogenated benzenes onto seven types of microplastics — including biodegradable bioplastics. At neutral pH (7), microplastics bound chlorinated phenols most strongly, while PAH and halogenated benzene adsorption was pH-independent. The findings matter because they show that even biodegradable plastic alternatives can carry toxic co-contaminants in freshwater systems, complicating the environmental safety case for bioplastics.
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.
Microplastics as potential bisphenol carriers: role of adsorbents, adsorbates, and environmental factors
Laboratory experiments showed that four common microplastic types — polystyrene, polypropylene, polyamide, and PVC — all readily adsorb bisphenols (BPA, BPB, BPF, BPS), with polyamide showing the highest capacity. Adsorption was strongly influenced by polymer surface chemistry, bisphenol hydrophobicity, temperature, and salinity. Because bisphenols are potent endocrine disruptors, microplastics acting as their environmental carriers could amplify human and wildlife exposure through contaminated seafood and drinking water.
Modelling of the adsorption of chlorinated phenols on polyethylene and polyethylene terephthalate microplastic
This study modeled how chlorinated phenols — toxic water pollutants — stick to polyethylene and polyethylene terephthalate microplastics sourced from personal care products. The findings suggest microplastics can act as carriers for harmful chemicals in aquatic environments, potentially concentrating toxins and delivering them to organisms that ingest the particles.
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.

Microplastics and organic contaminants: Investigation of the sorption process on different polymer types
Researchers investigated sorption of organic contaminants onto microplastics collected from environmental samples, finding that real-world MPs had different sorption capacities than laboratory-prepared particles due to surface aging, biofouling, and co-sorption of natural organic matter.
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.

Researchers characterized how three pesticides and three personal care products sorb onto high-density polyethylene microplastics in seawater. They found that more hydrophobic compounds accumulated more readily on the plastic, and that significant desorption (over 30%) occurred within 24 hours, especially at higher contaminant concentrations. The study confirms that microplastics can act as both carriers and releasers of chemical pollutants in marine environments.
