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.
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.
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.
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.
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.
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.
Sorption of organic compounds by aged polystyrene microplastic particles
Researchers tested the sorption of organic compounds by aged polystyrene microplastic particles and found that weathering increased their sorption capacity, meaning environmental aging makes microplastics more effective at accumulating and transporting pollutants.
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.
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.

This state-of-the-science review examined whether microplastics serve as vectors for bioaccumulation of hydrophobic organic chemicals in marine organisms. The study found that while microplastics can carry high concentrations of sorbed chemicals, their relative importance as an exposure route compared to other pathways like water and food remains an active area of research with varying conclusions depending on environmental conditions.

This study compared how quickly and how much pyrene — a common polycyclic aromatic hydrocarbon — is absorbed by different types of microplastics in aquatic environments. The results indicate that microplastic polymer type significantly affects how well it concentrates and potentially transports toxic organic chemicals.
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.
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.
Sorption of representative organic contaminants on microplastics: Effects of chemical physicochemical properties, particle size, and biofilm presence
This study examined how organic pollutants like flame retardants and industrial chemicals attach to microplastics in saltwater conditions.
