ClearThe 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.
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.
Occurrence and Fate of Emerging Contaminants with Microplastics Current Scenario, Sources and Effects
This review chapter covers the current state of microplastic contamination across marine and terrestrial environments, explaining how microplastics act as vectors for other pollutants — including pharmaceuticals, pesticides, and heavy metals — that accumulate on their surfaces. These contaminant-laden particles are consumed by marine organisms and travel up the food chain, reaching human food sources. The work underscores that microplastics are not just a physical hazard but also a chemical delivery system that amplifies the toxic burden on ecosystems and people.
Microplastics in ecosystems and health
This review summarizes how microplastics originate from degrading macroplastics and intentionally manufactured products, describes their impacts on marine organisms and human health, and surveys emerging recycling technologies and regulatory responses. It provides a useful plain-language synthesis of why microplastics are a dual environmental-and-health problem, acting both as physical contaminants and as vectors for toxic chemicals.
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.
A review on the combined toxicological effects of microplastics and their attached pollutants
Researchers reviewed how microplastics act as carriers for other environmental pollutants — including heavy metals and persistent organic chemicals — and how these combinations produce toxic effects in organisms that are more severe than either contaminant alone. The findings highlight a complex, layered toxicity problem that affects microbes, invertebrates, and vertebrates across marine and terrestrial environments.
Toxicity of microplastics in the marine environment.
This review chapter provides a broad and updated overview of microplastic ecotoxicology in marine environments, covering effects from the biochemical level through population and ecosystem scales. Evidence reviewed demonstrates that microplastics can act as physical hazards and chemical vectors affecting marine biodiversity across multiple trophic levels.
Trophic transfer of microplastics and mixed contaminants in the marine food web and implications for human health
This review examines how microplastics and the chemicals they carry transfer through marine food webs from lower to higher trophic levels, and what this means for human health given that people consume marine fish and seafood. It identifies microplastics as a vector for bioaccumulation of persistent organic pollutants in ways that ultimately reach humans.
Microplastics as contaminants in the marine environment: A review
This review synthesized the state of knowledge on microplastics as marine contaminants, covering their sources, pathways, distribution, biological uptake, and potential ecological and toxicological effects.
Microplastics in marine systems: A review of sources and sinks, typical environmental behaviors, and biological effects
This review summarizes how microplastics enter marine systems, carry heavy metals and organic pollutants, and release harmful additives as they degrade in the ocean. These contaminated particles are eaten by marine organisms and move up the food chain, ultimately posing potential health risks to humans who consume seafood.
Microplastic in marine organism: Environmental and toxicological effects
This review examined microplastics as a complex mixture of polymers, additives, and adsorbed environmental contaminants, and assessed their toxicological effects on marine organisms from ingestion and internal distribution. The authors emphasize that microplastic harm comes not only from the plastic itself but from the chemical cocktail it carries, and review the growing evidence for food web transfer.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
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.
Microplastic: Its Effect on Human Health
This review outlines how microplastics from single-use packaging, bottles, and consumer goods enter the food chain through ingestion and inhalation, serving as carriers for toxic chemical additives and adsorbed pollutants that pose risks to human health.
Microplastics as contaminants in marine environment.
This review summarizes the sources, distribution, and environmental impacts of microplastics in the marine environment, covering how they enter the ocean, where they accumulate, and what harms they cause to marine organisms. It also discusses the potential for microplastics to transfer up the food chain to humans through seafood.
The Individual and Combined Effects of Microplastics and Heavy Metals on Marine Organisms
This review summarizes how microplastics and heavy metals individually and together affect marine organisms. Microplastics can absorb heavy metals from the water and carry them into organisms, creating combined toxic effects that are often worse than either pollutant alone. Since these contaminants accumulate up the food chain and end up in seafood, this combined pollution poses a potential threat to human health through diet.
Microplastics as carriers of toxic pollutants: Source, transport, and toxicological effects
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.
Microplastics pollution in the marine environment: A review of sources, impacts and mitigation
This review summarizes how millions of tons of plastic waste enter the oceans each year and break into microplastics that absorb pollutants, heavy metals, and chemical additives. These contaminated particles pose risks to human health when they enter the food chain through seafood consumption.
A review of microplastics in the aquatic environmental: distribution, transport, ecotoxicology, and toxicological mechanisms
This review examines how microplastics are distributed, transported, and accumulate throughout aquatic environments, and the toxicological effects they have on aquatic organisms. The study suggests that microplastics can affect human health through the food chain, but notes that understanding of combined toxicity mechanisms remains very limited. The authors identify significant knowledge gaps and call for more systematic environmental risk assessments across multiple species.
Micro(nano)plastics: Unignorable vectors for organisms
This review examines the role of micro- and nanoplastics as vectors for contaminants — including heavy metals, organic pollutants, and pathogens — in aquatic and terrestrial environments. It synthesizes evidence on how plastic particles can adsorb, transport, and release harmful substances, amplifying their ecological and health risks beyond the physical effects of the particles alone.
