ClearInteraction 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.
Influence of polyethylene-microplastic on environmental behaviors of metals in soil
Researchers investigated how polyethylene microplastics affect the adsorption, desorption, and bioavailability of heavy metals in soil. They found that adding microplastics altered how metals bind to soil particles and increased the mobility of certain metals like cadmium and lead. The study suggests that microplastic contamination in soils may change the environmental behavior of heavy metals, potentially increasing their availability to plants and soil organisms.
Influencing mechanisms of microplastics existence on soil heavy metals accumulated by plants
This review summarizes existing research on how microplastics in soil affect the uptake of heavy metals by plants.

The study highlights major gaps in current analytical methods and calls for better tools to understand these complex pollutant interactions.
A critical review of co-pollution of microplastics and heavy metals in agricultural soil environments
This review examines how microplastics and heavy metals frequently occur together in agricultural soil, where they interact in ways that can increase the toxicity of both. These co-contaminants can harm soil organisms, reduce crop productivity, and potentially enter the human food chain, making their combined presence in farmland a growing concern for food safety and health.
Microplastics and Co‐Contaminants in Soil: A Review of Combined Ecological Impact and Emerging Remediation Strategies
This review synthesizes evidence on how microplastics in soil interact with co-contaminants including heavy metals, pharmaceuticals, and persistent organic pollutants, finding that microplastics modify the mobility, bioavailability, and toxicity of these co-occurring pollutants in ways that current risk assessments do not fully capture.
Research Progress on the Adsorption and Their Mechanisms of Heavy Metal in Soil By Microplastics
This review examines how microplastics adsorb heavy metals in soil environments, summarizing mechanisms including electrostatic attraction, surface complexation, and hydrophobic interactions that make MPs effective vectors for metal transport and bioavailability.
Microplastic Pollution in Terrestrial Ecosystems and Its Interaction with Other Soil Pollutants: A Potential Threat to Soil Ecosystem Sustainability
This review examines microplastic pollution in soils and how plastic particles interact with other pollutants like pesticides and heavy metals. About 80% of all plastic waste produced in the last 75 years has ended up in landfills or the environment, where it breaks into microplastics that alter soil health and contaminate crops. The combined effects of microplastics with other soil pollutants could threaten food safety and ultimately human health.
Combined pollution of soil by heavy metals, microplastics, and pesticides: Mechanisms and anthropogenic drivers
This study investigated how heavy metals, microplastics, and pesticides interact when they contaminate soil together, finding that their combined effects are complex and often worse than any single pollutant. Microplastics can absorb and concentrate both heavy metals and pesticides, changing how these chemicals move through soil and into plants. The findings highlight how agricultural soils contaminated with multiple pollutants could increase human exposure through crops grown in that soil.
Effect of Microplastics on the Adsorption and Desorption Properties of Cadmium in Soil
Polyethylene and polypropylene microplastics were found to reduce soil's capacity to adsorb cadmium, a toxic heavy metal, raising concerns that microplastic contamination in farmland soils could increase the mobility and risk of heavy metal pollutants.

Coexistence of microplastics and heavy metals in soil: Occurrence, transport, key interactions and effect on plants
This review examines how microplastics and heavy metals like lead, cadmium, and arsenic interact in soil, often creating combined toxic effects on plants that differ from either pollutant alone. These interactions are relevant to human health because contaminated crops can transfer both microplastics and heavy metals to people through the food supply.
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.

This study tested how five common types of microplastics affect soil properties and heavy metal availability in agricultural soil over 90 days. Microplastics changed soil structure, nutrient levels, and water-holding capacity, and actually reduced the availability of toxic heavy metals at higher plastic concentrations -- highlighting the complex ways plastic pollution is altering the farmland that produces our food.
Effects of combined microplastics and heavy metals pollution on terrestrial plants and rhizosphere environment: A review
This review summarizes how microplastics and heavy metals interact in soil to affect plant growth and the surrounding ecosystem. When present together, these pollutants cause significantly more harm than either alone, reducing plant weight by up to 87.5% and altering how heavy metals accumulate in crops -- raising concerns about food safety and human exposure through contaminated agricultural products.
Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
Traditional microplastics alter microbial community, metabolites and nutrition in heavy metal-contaminated coastal saline soil
Researchers added three types of microplastics to coastal soil already contaminated with heavy metals (cadmium, copper, and zinc), finding that the plastics altered soil chemistry, shifted microbial communities, disrupted metabolic pathways, and changed how available the toxic metals were to organisms. These findings suggest microplastics can worsen existing heavy metal pollution by changing how metals move through soil ecosystems.
Coupled effects of microplastics and heavy metals on plants: Uptake, bioaccumulation, and environmental health perspectives
This review examines how microplastics and heavy metals work together to harm plants when both are present in soil. Microplastics can absorb heavy metals like lead, cadmium, and arsenic, and when plants take up these contaminated particles, the combined toxic effect is worse than either pollutant alone. This is concerning for human health because crops grown in contaminated soil could carry both microplastics and concentrated heavy metals into the food supply.

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.
