ClearThe 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.
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.
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.

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.
Microplastics as vectors of organic pollutants in aquatic environment: A review on mechanisms, numerical models, and influencing factors
This review examines how microplastics act as carriers for organic pollutants in water, adsorbing chemicals like pesticides and pharmaceuticals onto their surfaces and transporting them through aquatic environments. Researchers analyzed the mechanisms behind this process, including hydrophobic interactions and surface adsorption, along with the mathematical models used to predict pollutant uptake. The study highlights that microplastics may amplify the environmental impact of other contaminants by concentrating and redistributing them.
A systematic review of microplastics in the environment: Sampling, separation, characterization and coexistence mechanisms with pollutants
Massive microplastic pollution was documented across Africa, Asia, India, South Africa, North America, and Europe, with MPs acting as carriers of heavy metals that enter organisms and cause harm. The adsorption capacity of organic pollutants onto microplastics correlated with hydrophobicity, surface area, and functional group characteristics.
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.
The Dual Role of Microplastics in Marine Environment: Sink and Vectors of Pollutants
This review examines the dual role of microplastics in the marine environment as both accumulators of persistent organic pollutants and vectors that transport these chemicals and other contaminants including heavy metals, pharmaceuticals, and pathogens. The study highlights how microplastics can concentrate toxic substances from seawater and then release them when ingested by marine organisms, creating additional exposure pathways.
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.
Effects of Microplastic Pollution on Marine Environment: a Mini Review
This review examines the formation, distribution, and ecological impacts of microplastics in marine environments, highlighting how their high adsorption capacity enables them to concentrate persistent organic pollutants and how long-term tissue accumulation poses risks to marine organisms and human health.
Microplastics as sorption materials of herbicides, persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in a coastal bay
Researchers analyzed microplastics collected from the Bay of Brest in France and found that the particles had absorbed herbicides, persistent organic pollutants, and polycyclic aromatic hydrocarbons from surrounding waters. The type and amount of chemicals adsorbed varied depending on the plastic polymer and the environmental conditions. The study confirms that microplastics in coastal environments act as carriers for other harmful pollutants, potentially spreading contamination through marine food webs.
Organic Pollutants Associated with Plastic Debris in Marine Environment: A Systematic Review of Analytical Methods, Occurrence, and Characteristics
This systematic review summarizes research on organic pollutants that attach to plastic debris in marine environments. The findings are concerning for human health because microplastics in the ocean can absorb and carry toxic chemicals like pesticides and flame retardants, and when marine life ingests these contaminated particles, the pollutants can move up the food chain to our seafood.
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. The study calls for more standardized research methods to better understand whether microplastics meaningfully increase human and wildlife exposure to these co-pollutants.
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.
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.

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.

Researchers analyzed 167 studies on microplastics in ocean surface waters and marine organisms, finding that fragments and fibers are the most common particle types across all regions studied. The review highlights that microplastics act as carriers for other harmful pollutants, increasing the chemical burden on marine life. The uneven global distribution of research means that microplastic contamination in many ocean regions remains poorly understood.
