A systematic review of microplastics in the environment: Sampling, separation, characterization and coexistence mechanisms with pollutants
Massive microplastic pollution was documented across Africa, Asia, India, South Africa, North America, and Europe, with MPs acting as carriers of heavy metals that enter organisms and cause harm. The adsorption capacity of organic pollutants onto microplastics correlated with hydrophobicity, surface area, and functional group characteristics.
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.
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.
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.
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.
