ClearThe aging of polyethylene mulch films in the presence of cadmium.
This study examined how cadmium in agricultural soil accelerates the aging and degradation of polyethylene mulch film over 150 days, finding that higher cadmium concentrations led to greater film deterioration. The results suggest that heavy metal pollution can increase the rate at which mulch films break down into microplastics in contaminated farmland soils.
Co-transport of degradable microplastics with Cd(Ⅱ) in saturated porous media: Synergistic effects of strong adsorption affinity and high mobility
Researchers investigated the co-transport of degradable microplastics with cadmium in saturated porous media, finding that these plastics' strong adsorption affinity and high mobility create synergistic effects that enhance heavy metal migration in soil.
Behaviour, ecological impacts of microplastics and cadmium on soil systems: A systematic review
This systematic review examines how microplastics and cadmium interact in soil, finding that they can make each other more harmful. Microplastics can carry toxic cadmium further through soil and increase its uptake by plants, which could mean more heavy metal contamination in the food we eat.
[Effects of Microplastics Coexisting in Vegetable Soil on the Change of Cadmium Bioavailability].
Researchers investigated the effects of biodegradable microplastics co-occurring with cadmium in vegetable soil through a 60-day pot experiment with lettuce, examining how the combined contamination alters cadmium bioavailability and uptake relative to cadmium-only or microplastic-only conditions.
Insight into the interactions between microplastics and heavy metals in agricultural soil solution: adsorption performance influenced by microplastic types
Environmental-simulating microplastics (aged under environmental conditions) showed higher cadmium and chromium adsorption capacity than commercial microplastics in agricultural soil solutions, with surface oxidation increasing adsorption—suggesting that aged microplastics are more effective co-transporters of heavy metals in contaminated agricultural soils.
Unveiling the impacts of microplastics on cadmium transfer in the soil-plant-human system: A review
A meta-analysis found that microplastics significantly increase soil cadmium bioavailability by 6.9% and cadmium accumulation in plant shoots by 9.3%, through both direct surface adsorption and indirect modification of soil pH and dissolved organic carbon. This enhanced cadmium mobility through the soil-plant-human food chain amplifies health risks, as co-ingestion of microplastics and cadmium increases cadmium bioaccessibility and tissue damage.
Microplastics in soils with contrasting texture, organic carbon and mineralogy: changes in cadmium adsorption forms and their mobility in soil columns
This study investigated how high-density polyethylene microplastics alter the behavior of cadmium — a toxic heavy metal — in soils with different textures, organic carbon contents, and mineral compositions. Using soil column experiments, researchers found that microplastics changed how cadmium binds to soil particles and how easily it leaches downward, with effects varying depending on the soil type and microplastic particle size. Since cadmium is a known carcinogen and agricultural soils commonly contain both microplastics and heavy metals, understanding their interactions is critical for food safety.
Effects of microplastics and cadmium on the soil-wheat system as single and combined contaminants
Researchers found that polyethylene and polypropylene microplastics combined with cadmium reduced wheat chlorophyll concentrations and affected soil-plant systems differently depending on pollution levels, revealing complex interaction effects between co-contaminants.
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.
Differential Impactsof Conventional and BiodegradableMicroplastics on Cadmium Transfer in a Soil-Earthworm-Lettuce System
A microcosm experiment tested how conventional and biodegradable microplastics affected cadmium transfer in a soil-earthworm-lettuce system. High doses of conventional MPs increased cadmium in plant shoots by 54% and in earthworms by 80%, while biodegradable MPs had less effect, suggesting polymer type matters for metal contamination risk in agroecosystems.
Typical microplastics in field and facility agriculture dynamically affect available cadmium in different soil types through physicochemical dynamics of carbon, iron and microbes
Researchers found that polyurethane and polypropylene microplastics dynamically affect cadmium availability in different soil types through changes in soil carbon chemistry, iron mineral forms, and microbial community composition, with effects varying between field and greenhouse agricultural conditions.
Effects of microplastics and cadmium co-contamination on soil properties, maize (Zea mays L.) growth characteristics, and cadmium accumulation in maize in loessial soil-maize systems
Researchers studied the combined effects of polyethylene microplastics and cadmium on soil properties and maize growth through pot experiments. They found that microplastics altered soil nutrient availability and, depending on size and concentration, either increased or decreased cadmium uptake by the plants. The study suggests that microplastic contamination in agricultural soils can change how crops absorb toxic heavy metals, with potential implications for food safety.
[Effects of Microplastics on the Leaching of Nutrients and Cadmium from Soil].
A soil column experiment showed that polystyrene and polylactic acid microplastics at varying concentrations affected how nutrients (nitrogen, phosphorus, potassium) and the heavy metal cadmium leach out of soil during simulated rainfall. Higher microplastic concentrations generally altered leaching patterns, raising concerns that microplastic contamination in agricultural soils could change nutrient availability for crops and increase the mobility of toxic heavy metals into groundwater.
