Persistent organic pollutants carried on plastic resin pellets from two beaches in China
Researchers found that plastic resin pellets collected from two Chinese beaches contained significant concentrations of PAHs, PCBs, organochlorine pesticides, and other persistent organic pollutants sorbed to their surfaces. The findings confirm that plastic pellets act as vectors for long-range transport of multiple classes of hydrophobic chemical contaminants in marine environments.
Microplastics and associated polycyclic aromatic hydrocarbons in surface water and sediment of the Bay of Bengal coastal area, India: sources, pathway and ecological risk
Researchers surveyed microplastic contamination in surface water and sediment along two Bay of Bengal coastal beaches in India and found microplastics present at both sites. They also detected polycyclic aromatic hydrocarbons, a group of harmful chemicals, adsorbed onto the microplastic surfaces at concentrations that varied by particle shape. The study highlights that microplastics in coastal waters act as carriers for toxic organic pollutants, potentially increasing ecological risks in the marine environment.
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.
Determination of organochlorine pesticides adsorbed on plastic pellets
Researchers analyzed organochlorine pesticides adsorbed onto plastic pellets found in coastal environments, contributing to understanding of how plastic debris accumulates and concentrates toxic chemicals. Plastic pellets, a type of microplastic, can act as carriers bringing persistent organic pollutants into marine food webs.
Caracterización de POPs y PAHs en fragmentos plásticos: Estudio de Caso en el Callao
Researchers characterized persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) adsorbed onto plastic fragments collected from a Colombian Caribbean beach. High concentrations of these toxic chemicals were found on weathered plastic surfaces, raising concerns about chemical transfer to organisms.
Organic pollutants in microplastics from two beaches of the Portuguese coast
Microplastic samples from two Portuguese beaches were analyzed for persistent organic pollutants including PAHs and PCBs, with sorbed concentrations varying by plastic color and degree of weathering. The study confirms that beached microplastics carry toxic organic chemicals and that older, more weathered particles tend to carry higher contaminant loads.
Accumulation of persistent organic pollutants by MPs in coastal wastewater treatment plants
Researchers examined how microplastics in coastal wastewater treatment plants accumulate persistent organic pollutants such as dioxins, furans, and PCBs. They found that untreated influent contained the highest concentrations of these hazardous chemicals sorbed onto microplastic surfaces. The study highlights that microplastics can act as carriers for toxic pollutants through wastewater systems and into the environment.
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.
Physico-chemical characterisation of plastic waste in the Togolese marine environment with a view to recovery
Researchers physically and chemically characterized plastic waste collected from Togo's marine environment, assessing the biodegradability of different polymer types to inform recovery and pollution reduction strategies for West African coastal ecosystems.
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.
Association between PAH and plastic fragments on Brazilian coast beaches: a baseline assessment
Researchers conducted a baseline assessment of the association between polycyclic aromatic hydrocarbons (PAHs) and plastic fragments collected from beaches along the Brazilian coast, characterising how microplastics act as adsorption surfaces for these organic pollutants. The study found co-occurrence of PAHs and plastic fragments at sampled sites, establishing contamination baselines and informing understanding of the plastic-pollutant vector pathway.
Adsorption profiles and potential risks of PAHs and PCBs on microplastics in stormwater runoff: Influence of underlying surfaces and polymer materials
This study examined how microplastics in stormwater runoff absorb cancer-linked chemicals called PAHs and PCBs from different urban surfaces like roads, rooftops, and green spaces. The type of plastic and the surface it washed off determined how much of these toxic chemicals it carried. This matters because stormwater is increasingly being harvested for reuse, and contaminated microplastics could introduce hazardous chemicals into water supplies.
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.

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.
Marine microplastics as vectors of major ocean pollutants and its hazards to the marine ecosystem and humans
Researchers reviewed how microplastics in the ocean act as "hitchhikers" for other pollutants — absorbing and carrying heavy metals, pesticides, and chemicals into marine food webs and ultimately toward humans. While direct proof of microplastic harm to humans is still limited, the accumulated evidence of toxic chemical transport through seafood and drinking water raises serious concern.
The sorption of persistent organic pollutants in microplastics from the coastal environment

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.

This study found that the type and characteristics of microplastics present in marine organisms from Sanggou Bay, China, influenced how much of the harmful chemical pollutant PAH (polycyclic aromatic hydrocarbons) accumulated in their tissues. Smaller, more degraded microplastics carried more PAHs into organisms, raising the human health risk from eating contaminated seafood and highlighting that microplastics act as vehicles for other toxic chemicals.
