ClearSorption of polyhalogenated carbazoles (PHCs) to microplastics
Researchers investigated the sorption of five polyhalogenated carbazoles onto polyethylene, polypropylene, and polyvinyl chloride microplastics, finding that sorption capacity varied with plastic type and carbazole structure, indicating that microplastics can act as vectors for these emerging halogenated organic contaminants.
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. Smaller microplastic particles absorbed more contaminants per unit weight, and natural biofilms growing on the plastic surfaces changed how much pollution they could carry. The findings help explain how microplastics act as carriers of toxic chemicals through the environment and potentially into the food chain.
Adsorption and Desorption Behaviour of Polychlorinated Biphenyls onto Microplastics’ Surfaces in Water/Sediment Systems
Researchers evaluated the adsorption and desorption behavior of polychlorinated biphenyls (PCBs) onto polystyrene, polyethylene, and polyethylene terephthalate microplastics of varying sizes in marine water/sediment systems. Results showed that polymer type and particle size influenced PCB binding capacity, with microplastics acting as potential vectors for transferring persistent organic pollutants to marine biota through the food chain.
Enrichment of Persistent Organic Pollutants in Microplastics from Coastal Waters
Researchers quantified how microplastics concentrate persistent organic pollutants compared to suspended particulate matter in coastal seawater. They found that the concentrating effect of microplastics on these pollutants was one to two orders of magnitude greater than that of natural suspended particles. The study provides precise measurements of enrichment factors, suggesting that microplastics may serve as significant carriers of toxic organic chemicals in marine environments.
Sorption and dissipation of current-use pesticides and personal-care products on high-density polyethylene microplastics in seawater
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.
Sorption of 3,3′,4,4′-tetrachlorobiphenyl by microplastics: A case study of polypropylene
This study measured the sorption of a polychlorinated biphenyl (PCB) congener onto polyethylene and polypropylene microplastics, finding that both polymers had high sorption capacity influenced by salinity, temperature, and the presence of other organic matter. The results help predict how microplastics transport PCBs in marine environments and potentially deliver 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.
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.
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.
Removed Due to Policy Violations
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.

Researchers examined the sorption of tris-(2,3-dibromopropyl) isocyanurate and hexabromocyclododecanes (HBCDs) onto polypropylene microplastics in simulated seawater, finding that particle size, temperature, salinity, and concentration all influenced adsorption behavior and the potential for microplastics to act as vectors for these brominated flame retardants.
Sorption of alkylphenols and estrogens on microplastics in marine conditions
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.
Les microplastiques en milieu marin : supports de contaminants chimiques - Étude bibliographique
This French bibliographic review examined 121 papers on microplastics as carriers of chemical contaminants in marine environments, synthesizing what is known about how pollutants adsorb to and desorb from plastic surfaces. The ability of microplastics to concentrate persistent organic pollutants like PCBs and pesticides from seawater and potentially release them to marine organisms is a key concern.
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.

Competitive sorption of persistent organic pollutants onto microplastics in the marine environment
This study tested whether phenanthrene and DDT compete with each other for sorption sites on PVC microplastics when present as a mixture in seawater, and found that competition reduced sorption of each compound compared to when tested alone. The finding has implications for predicting how microplastics transport chemical mixtures in the ocean, which is more realistic than single-compound tests.
