Research progress on environmental occurrence of microplastics and their interaction mechanism with organic pollutants
AI summary Read the abstract
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.
Microplastics are ubiquitous in various environmental media on a global scale, and can adsorb co-existing pollutants, especially organic pollutants, thus changing the environmental behavior and toxicity of pollutants; they can also promote the migration of pollutants in different media through adsorption/desorption. Influencing factors and mechanisms of adsorption between microplastics and organic pollutants are necessary information for a comprehensive assessment of the environmental risks of microplastics and organic pollutants. Due to the complexity of composition, structure and surface characteristics of microplastics and the diversity of co-existing organic pollutants, the interaction between them is very complex. The authors systematically summarized the current status of occurrence and migration of microplastic in environmental media, the influencing factors of microplastic adsorption of organic pollutants and their interaction mechanisms, with a view to providing useful references for the in-depth understanding of the environmental behavior and ecological risks of microplastics.

Transport of persistent organic pollutants: Another effect of microplastic pollution?
AI summary Read the abstract
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.
Interactions Between Microplastics and Organic Pollutants in Aquatic Systems: Impacts on Environmental Fate, Transport, and Risk Assessment
AI summary Read the abstract
Researchers reviewed how microplastics interact with organic pollutants in aquatic environments, finding that sorption is highly context-dependent and influenced by polymer type, pollutant chemistry, and weathering, while detection of MPs in human tissues raises ongoing concerns about inflammation, immune disruption, and endocrine effects that current analytical methods cannot fully resolve.
Progress on the interaction between microplastics and contaminants
AI summary Read the abstract
This review examines the two-way interactions between microplastics and environmental contaminants such as heavy metals, organic pollutants, and microorganisms. Researchers found that microplastics act as carriers that alter contaminant fate and transport, while contaminants in turn change microplastic properties and behaviour.
Microplastics as carriers of toxic pollutants: Source, transport, and toxicological effects
AI summary Read the abstract
This review summarizes how microplastics absorb and carry toxic pollutants like persistent organic pollutants, heavy metals, and antibiotics through the environment, concentrating these harmful chemicals as they move through ecosystems. When organisms ingest these contaminated particles, the pollutants can build up in the food chain and eventually reach humans, making microplastics not just a physical hazard but also a chemical delivery system.
Interactions of Microplastics with Persistent Organic Pollutants and the Ecotoxicological Effects: A Review
AI summary Read the abstract
This review examines how microplastics interact with persistent organic pollutants in the environment, including how factors like salinity, pH, and plastic type affect the sorption of toxic chemicals onto microplastic surfaces. The study suggests that when organisms ingest microplastics loaded with these pollutants, the chemicals can be released inside the body, posing combined ecotoxicological risks.
