ClearMicroplastics 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.

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.

A study found that microplastics in soil can change how much cadmium, a toxic heavy metal, is absorbed by food crops, with the effects varying depending on soil type and the amount of plastic present. By altering soil chemistry and bacterial communities, microplastics reshape how pollutants move through farmland and into the food we eat.
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.
[Effects of Polystyrene Microplastics Combined with Cadmium Contamination on Soil Physicochemical Properties and Physiological Ecology of Lactuca sativa].
Researchers studied the combined effects of polystyrene microplastics and cadmium contamination on soil properties and lettuce growth. The study found that the co-presence of microplastics and heavy metals altered soil physicochemical characteristics and affected plant physiological responses, indicating that compound contamination from microplastics and metals may pose greater risks to agricultural systems than either pollutant alone.
Polyethylene microplastics increase cadmium uptake in lettuce (Lactuca sativa L.) by altering the soil microenvironment
This study found that polyethylene microplastics in soil increased the amount of cadmium, a toxic heavy metal, that lettuce plants absorbed. The microplastics changed soil chemistry by lowering pH and increasing dissolved organic carbon, which made cadmium more available for plant uptake. This is concerning because it suggests that microplastics in agricultural soil could make crops more contaminated with heavy metals, increasing the health risks for people who eat them.
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.
Influences of coexisting aged polystyrene microplastics on the ecological and health risks of cadmium in soils: A leachability and oral bioaccessibility based study
This study tested whether the presence of aged microplastics in soil changes how easily the toxic heavy metal cadmium can enter the human body through accidental soil ingestion. The results showed that aged polystyrene microplastics actually reduced cadmium absorption in the stomach phase, though the effect varied by soil type. This suggests that the interaction between microplastics and other pollutants in soil creates a complicated picture for assessing human health risks.
Impact of polystyrene microplastics on cadmium uptake in corn (Zea mays L.) in a cadmium‐contaminated calcareous soil
This study found that polystyrene microplastics in soil increased the uptake of the toxic heavy metal cadmium in corn plants. The research showed that microplastic contamination in agricultural soil can make crops absorb more harmful substances. This is a direct concern for food safety, as microplastics in farmland could increase our exposure to heavy metals through the food we eat.
[Characteristics and Mechanism of Cd Release and Transport in Soil Contaminated with PE-Cd].
Researchers investigated how polyethylene (PE) microplastics affect the sorption and transport of cadmium (Cd) in soil, examining the characteristics and mechanisms of Cd release under PE contamination. Their findings reveal that microplastics alter soil physicochemical properties and sorption capacity, influencing heavy metal mobility and distribution in terrestrial ecosystems.

Microplastics in Soil Increase Cadmium Toxicity: Implications for Plant Growth and Nutrient Imbalance
A pot experiment showed that adding polyethylene microplastics to soil contaminated with cadmium made the toxic metal more available to plants, increasing cadmium uptake in both roots and shoots. The combined exposure reduced crop yields by up to 38% and disrupted the plant's ability to absorb essential nutrients like nitrogen and phosphorus. This research is important for food safety because it shows microplastics in farm soil can make heavy metal contamination worse, potentially increasing toxic metal levels in crops people eat.
Impacts of polypropylene microplastics on the distribution of cadmium, enzyme activities, and bacterial community in black soil at the aggregate level
Researchers found that adding polypropylene microplastics to soil contaminated with cadmium (a toxic heavy metal) changed how the metal distributed across different soil particle sizes and shifted bacterial communities. The microplastics increased cadmium availability in some soil fractions, potentially making it easier for plants to absorb this toxic metal. This suggests that microplastic-contaminated farmland may pose greater heavy metal exposure risks for crops and, ultimately, for people who eat them.

Researchers studied how polyethylene microplastics interact with cadmium contamination in soil and its effects on lettuce growth. The study found that microplastics combined with cadmium significantly decreased soil quality and that microplastics can alter cadmium uptake in plants, suggesting that co-contamination of agricultural soils with both pollutants may pose compounded risks to food crop safety.
Microplastics promoted cadmium accumulation in maize plants by improving active cadmium and amino acid synthesis
Researchers examined how polystyrene and polypropylene microplastics interact with cadmium contamination to affect soil chemistry and cadmium uptake in maize plants across two soil types. The study found that microplastics generally promoted cadmium accumulation in maize by reducing soil pH and increasing cadmium bioavailability, with effects varying by particle size depending on the soil type.
Effects of Co-Contamination of Microplastics and Cd on Plant Growth and Cd Accumulation
Researchers investigated how two types of microplastics, high-density polyethylene and polystyrene, at various concentrations affect cadmium uptake and toxicity in maize plants grown in agricultural soil. The study found that while polyethylene alone had no significant effect, polystyrene at higher doses altered cadmium accumulation patterns, suggesting that different plastic types may interact differently with heavy metals in soil.

Researchers tested how different microplastic types combined with cadmium affect plant growth and soil health. Aged and biodegradable microplastics increased cadmium uptake in mustard greens more than fresh conventional plastics did. The study also found that microplastics altered soil microbial activity, suggesting that plastic pollution in farmland could change how plants absorb toxic metals from contaminated soil.
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.
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 polyethylene microplastics and cadmium co-contamination on the soybean-soil system: Integrated metabolic and rhizosphere microbial mechanisms
Researchers investigated how polyethylene microplastics and cadmium interact in soybean-soil systems and found that specific microplastic concentrations enhanced cadmium accumulation in roots under moderate contamination.
