ClearMicroplastics 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.
Co-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.
Influence 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.
Interaction of microplastics with heavy metals in soil: Mechanisms, influencing factors and biological effects
This review summarizes how microplastics and heavy metals interact in soil, where microplastics can absorb and carry toxic metals through the food chain and into the human body. Aging and weathering of microplastics changes their surface properties, making them better at picking up heavy metals, which raises concerns about combined exposure through contaminated crops and water.
Interactions and effects of microplastics with heavy metals in aquatic and terrestrial environments
This review explores how microplastics absorb toxic heavy metals from the environment and what happens when organisms ingest these contaminated particles. In the acidic conditions of an animal's digestive system, metals can separate from the plastic and accumulate in body tissues. Since heavy metals can concentrate on microplastics and then transfer up the food chain, this combination poses a compounded health risk to wildlife and potentially to humans who eat contaminated seafood.
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.
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.
Microplastic-mediated environmental behavior of metal contaminants: mechanism and implication
This review examines how microplastics interact with heavy metals across water, soil, and air environments, acting as carriers that concentrate and transport toxic metals. Researchers found that microplastics can increase the bioavailability and toxicity of metal contaminants to living organisms. The study highlights major gaps in current analytical methods and calls for better tools to understand these complex pollutant interactions.
A critical review on the interactions of microplastics with heavy metals: Mechanism and their combined effect on organisms and humans
This review examines how microplastics interact with heavy metals in the environment and what their combined effects mean for organisms and human health. Microplastics absorb heavy metals from surrounding water and soil, and when ingested, the acidic conditions in the gut can cause those metals to be released inside the body. The combination of microplastics and heavy metals may be more toxic than either pollutant alone, creating a compounded health risk.
Co-exposure of microplastics and heavy metals in the marine environment and remediation techniques: a comprehensive review
This review examines how microplastics and heavy metals interact when they co-exist in the marine environment, with microplastics acting as carriers that concentrate metals on their surfaces. Researchers describe the mechanisms behind this interaction, including surface complexation, hydrogen bonding, and electrostatic forces. The study also surveys current remediation techniques aimed at removing both microplastics and heavy metal-laden microplastics from marine ecosystems.
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.
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.
Reviewing the role of microplastics as carriers for microorganisms in absorbing toxic trace elements
This review examines how microplastics serve as carriers for both harmful bacteria and toxic metals in the environment. Bacteria colonize microplastic surfaces and form biofilms, which can concentrate dangerous trace elements and help spread pathogens to new areas. This dual role as a transport vehicle for both chemical and biological contaminants increases the potential risk to human health through contaminated water and food.
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.

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.
