ClearMicroplastics as vectors of environmental contaminants: Interactions in the natural ecosystems
This review examines how microplastics act as vectors for pathogens, persistent organic pollutants, and heavy metals in marine, freshwater, and terrestrial ecosystems, summarising evidence that these particles damage cell membranes, tissues, and physiological processes in exposed organisms.
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.
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.
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.
Ecological and toxicological manifestations of microplastics: current scenario, research gaps, and possible alleviation measures
This review examines the ecological and toxicological effects of microplastics and their associated contaminants across aquatic and terrestrial environments, identifying key knowledge gaps and potential mitigation strategies. The authors emphasize that both physical particle effects and co-transported chemical pollutants pose compounding risks to wildlife and ecosystems.
Interaction of Environmental Pollutants with Microplastics: A Critical Review of Sorption Factors, Bioaccumulation and Ecotoxicological Effects
This critical review examines how microplastics interact with and enhance the toxicity of co-occurring environmental pollutants including heavy metals, persistent organic compounds, and pharmaceuticals, synthesizing evidence on sorption mechanisms and combined ecotoxicological effects.
Interactions of microplastics with organic, inorganic and bio-pollutants and the ecotoxicological effects on terrestrial and aquatic organisms
This review systematically examines how microplastics interact with organic pollutants, heavy metals, and biological contaminants in the environment. Researchers found that microplastics can adsorb and transport these pollutants, creating complex combinations that may be more toxic to organisms than either pollutant alone. The study highlights the risks these interactions pose to both ecosystem health and human well-being.
Interactive effects of micro/nanoplastics and nanomaterials/pharmaceuticals: Their ecotoxicological consequences in the aquatic systems
Researchers reviewed how micro- and nanoplastics interact with co-occurring nanomaterials and pharmaceuticals in aquatic environments, finding that plastics act as vectors that can either amplify or attenuate the bioavailability and toxicity of these contaminants depending on species, trophic level, and environmental conditions.
Environmental Toxicity and Bioaccumulation of Microplastics Derived from Petroplastics: A Cross-Ecosystem Review
This review synthesizes over 150 studies on the environmental toxicity and bioaccumulation of microplastics derived from petroplastics across marine, freshwater, and terrestrial ecosystems. The findings indicate that microplastics disrupt food webs, serve as vectors for persistent organic pollutants, and accumulate in organisms across all ecosystem types, though terrestrial data remains comparatively scarce.
Microplastics and environmental pollutants: Key interaction and toxicology in aquatic and soil environments
This review tracks how microplastics move through soil, water, and air ecosystems, acting as carriers for other pollutants like pesticides and heavy metals. When microplastics absorb these toxins, the combined effect on organisms can be worse than either pollutant alone. The paper highlights the need for better understanding of how these pollutant combinations affect ecosystems and ultimately human health through contaminated food and water.
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 Contamination in the Environment: An Ecotoxicological Concern
This review examines the sources, distribution, and toxic effects of microplastics across terrestrial and aquatic environments. The authors summarize evidence that microplastics harm a wide range of organisms by causing physical injury, delivering chemical pollutants, and disrupting ecosystem processes.
