ClearInfluence of Microplastics on the Mobility, Bioavailability, and Toxicity of Heavy Metals: A Review
This review examines how microplastics interact with heavy metals in the environment, potentially influencing the metals' mobility, bioavailability, and toxicity to living organisms. Researchers found that microplastics can adsorb heavy metals and transport them to new locations, but the interactions depend on the type of plastic, metal, and environmental conditions. The study highlights that microplastics acting as carriers for toxic metals represents an underappreciated environmental and health risk.
Microplastics as a vehicle of heavy metals in aquatic environments: A review of adsorption factors, mechanisms, and biological effects
This review summarizes how microplastics in water can absorb and carry toxic heavy metals like lead and cadmium, making them more dangerous to aquatic life than either pollutant alone. Environmental factors such as water acidity, salinity, and organic matter influence how much metal sticks to microplastic surfaces. Since contaminated seafood is a major source of human exposure, understanding these interactions is important for assessing health risks.
Interactions of microplastics with heavy metals in the aquatic environment: Mechanisms and mitigation
This review synthesized mechanisms of heavy metal adsorption onto microplastics in aquatic environments and evaluated strategies for removing both contaminants simultaneously. The authors found that temperature, salinity, and plastic surface aging govern metal binding, and identified hybrid adsorbent materials as the most promising approach for co-removal of metals and microplastics from water.
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. Bacteria that colonize microplastic surfaces can change how metals bind to and release from the particles, potentially increasing their toxicity. The combined threat of microplastics and heavy metals to aquatic ecosystems and human health through seafood consumption is a growing concern that needs more research.
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.
Adsorption behavior of organic pollutants and metals on micro/nanoplastics in the aquatic environment
This review examines how micro- and nanoplastics in aquatic environments adsorb organic pollutants and metals onto their surfaces, effectively acting as carriers for other contaminants. Researchers found that environmental factors like pH, salinity, and aging of the plastic significantly influence this sorption behavior. The findings raise concerns that microplastics may increase the bioavailability and toxicity of chemical pollutants in waterways.
Interaction of microplastics with metal(oid)s in aquatic environments: What is done so far?
This review assembled the mechanisms by which microplastics sorb hazardous metals and metalloids in aquatic environments, examining how weathering, biofilm formation, and environmental conditions influence the transport and bioavailability of these contaminants.
Factors Affecting the Adsorption of Heavy Metals by Microplastics and Their Toxic Effects on Fish
This review examines how microplastics absorb heavy metals from water and how the combined pollution harms fish. Factors like water pH, temperature, and the age of the plastic all affect how much metal sticks to the surface. Since fish are a major protein source for humans, the combination of microplastics and heavy metals entering fish tissue is a potential pathway for these pollutants to reach people through their diet.
The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
This review examines how microplastics and heavy metals interact in water environments, finding that microplastics can attract and concentrate toxic metals on their surfaces through various chemical forces. This combination effect is a concern for human health because contaminated microplastics carrying heavy metals can be consumed through seafood, delivering a double dose of pollutants.
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.
The evolving interface of aged microplastics and heavy metals: implications for environmental fate and toxicity
This review examined how microplastics interact with heavy metals in the environment, focusing on how plastics serve as carriers that increase metal mobility and bioavailability. Researchers found that factors like polymer aging, biofilm formation, and water chemistry significantly affect how efficiently microplastics absorb metals, and that the combined exposure creates compounded toxicity including oxidative stress and organ damage in organisms. The findings highlight the need for more research on the long-term and multigenerational effects of these combined pollutants.

The role of microplastics biofilm in accumulation of trace metals in aquatic environments
This review examines how biofilms that form on microplastics in aquatic environments enhance the accumulation of trace metals from surrounding water. Researchers found that microorganisms colonizing plastic surfaces produce extracellular substances that facilitate metal sorption, effectively turning microplastics into concentrated carriers of metallic contaminants. The study highlights the dual pollution risk posed by microplastics serving as both physical pollutants and vehicles for toxic metal transport in waterways.
Interaction of plastic particles with heavy metals and the resulting toxicological impacts: a review
Researchers reviewed how micro- and nanoplastics interact with heavy metals in the environment, identifying electrostatic attraction and pore-filling as the dominant adsorption mechanisms, and finding that factors including pH, salinity, biofilm formation, and particle size collectively determine whether combined exposure produces synergistic toxicity in animals or antagonistic effects in plants.
The potential of microplastics as carriers of metals
Five types of microplastics were tested for their ability to adsorb heavy metals (Cd, Co, Cr, Cu, Ni, Pb, Zn) in different water matrices, finding significant adsorption of lead, chromium, and zinc—especially on polyethylene and PVC—with surface area and porosity as key drivers.
