ClearCo-occurrence and Interaction of Microplastics with Heavy Metals
This review examines the co-occurrence of microplastics and heavy metals in aquatic and terrestrial ecosystems, synthesizing evidence on how MPs adsorb metals, alter their bioavailability, and facilitate their transfer up food chains, compounding toxicological risks beyond either pollutant alone.
Microplastics exacerbate heavy metal pollution stress in the surface water of a mining city: Occurrence, drivers, and vector effects
Researchers studied the co-occurrence of microplastics and heavy metals in surface water of a coal mining city and found that microplastics act as vectors that exacerbate heavy metal transport and pollution. The study identified key drivers of combined contamination from mining activities, farmland reclamation, and urban runoff. The findings suggest that microplastics in mining regions amplify the environmental risks of heavy metal pollution by carrying and concentrating toxic metals.
Synergistic Impacts of Microplastics and Heavy Metals in Aquatic Environments and Strategies for Mitigation
This review examines the combined pollution of aquatic habitats by heavy metals and microplastics, covering their widespread distribution from polar regions to deep-sea sediments and the ecological risks of their interaction.

This review examines the Trojan-horse effect in freshwater environments where microplastics adsorb and transport heavy metals, significantly increasing their potential ecological harm due to the large surface area and persistence of microplastic particles.
Understanding the Adsorption Behavior of Heavy Metals onto the MPs and Their Impact
This review examines how microplastics adsorb heavy metals from soil and aquatic environments and how this adsorption affects the transport, bioavailability, and toxicity of both contaminants. The authors synthesize evidence showing that microplastics act as effective carriers for heavy metal transport through freshwater and marine systems, amplifying the ecological hazard of metal contamination.
Microplastics and potentially toxic elements: A review of interactions, fate and bioavailability in the environment
This review summarizes how microplastics interact with toxic metals in the environment, finding that microplastics absorb and transport metals through soil and water via processes like electrostatic attraction and surface bonding. When organisms consume microplastics carrying toxic metals, they can experience greater harm than from either pollutant alone. This combined threat is relevant to human health because contaminated microplastics in the food chain could deliver concentrated doses of toxic metals to people through food and water.

This review explores how microplastics interact with heavy metals in aquatic environments, acting as vectors that can adsorb and transport toxic metals through ecosystems. The combined toxicity of microplastic-metal complexes poses greater risks to aquatic organisms than either contaminant alone.
Interaction of Microplastics and Heavy Metals on Aquatic Organisms : A Review
This systematic review examines how microplastics interact with heavy metals in waterways, finding that plastic particles absorb toxic metals and then release them inside organisms that ingest them. This combination increases the toxicity of both pollutants, leading to DNA damage, tissue changes, and reproductive problems in aquatic life, with potential consequences for human health through the food chain.
Interactions Between Microplastics and Heavy Metals in Aquatic Environments: A Review
This review examines how microplastics interact with heavy metals in water, with a particular focus on the role that microorganisms play in driving these interactions.
