ClearInteractive effects of microplastics and cadmium on soil properties, microbial communities and bok choy growth
Researchers grew bok choy in soil amended with polyethylene microplastics (0.5-2% by weight) and cadmium to assess interactive effects on soil properties, microbial communities, and plant growth. Combined exposure produced distinct synergistic and antagonistic interactions compared to either pollutant alone, altering soil enzyme activity, bacterial diversity, and plant metal uptake.
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. Higher microplastic levels reduced beneficial soil bacteria like Sphingomonas and Bradyrhizobium and suppressed nitrogen-cycling functions. The study demonstrates that microplastics fundamentally alter heavy metal behavior through interconnected plant-metabolite-microbe interactions in agricultural soils.
Interactions of microplastics and cadmium on plant growth and arbuscular mycorrhizal fungal communities in an agricultural soil
Researchers studied how polyethylene and polylactic acid microplastics interact with cadmium contamination to affect maize growth and beneficial soil fungi in agricultural soil. While polyethylene showed minimal direct plant toxicity, high doses of polylactic acid significantly reduced maize biomass, and both plastic types altered the communities of root-associated fungi. The study suggests that co-contamination of microplastics and heavy metals in farmland can jointly disrupt plant health and soil ecosystems.
Combined effects of microplastics and cadmium on the soil-plant system: Phytotoxicity, Cd accumulation and microbial activity
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.
[Effects of Combined Pollution of Microplastics and Cadmium on Microbial Community Structure and Function of Pennisetum hydridum Rhizosphere Soil].
Researchers investigated the combined effects of microplastics (polyethylene and polystyrene at different particle sizes and concentrations) and cadmium on the growth of Pennisetum hydridum and the microbial community structure and function of rhizosphere soil under pot conditions. The results showed that the type, size, and concentration of microplastics interacted with cadmium to differentially affect plant dry weight, cadmium accumulation, and soil microbial diversity indices.
Rhizosphere microbiome metagenomics in PGPR-mediated alleviation of combined stress from polypropylene microplastics and Cd in hybrid Pennisetum
Researchers found that beneficial soil bacteria (PGPR) can help plants cope with the combined stress of polypropylene microplastics and the toxic heavy metal cadmium. The bacteria improved plant growth by 8-42% under contaminated conditions by reshaping the microbial community around plant roots. This study offers a potential strategy for maintaining crop productivity in farmland contaminated with both microplastics and heavy metals.
The Effects of Microplastics and Heavy Metals Individually and in Combination on the Growth of Water Spinach (Ipomoea aquatic) and Rhizosphere Microorganisms
Researchers tested how combinations of microplastics and heavy metals (cadmium and lead) affect the growth of water spinach and the microbial communities in its root zone. They found that all three stressors individually inhibited plant growth, and combining microplastics with heavy metals intensified the toxic effects while reducing the availability of essential soil nutrients. The study suggests that microplastic-heavy metal interactions in agricultural soils may pose compounding risks to both crop health and soil ecosystem function.
Assessing heterogeneous pollution risks from polystyrene micro(nano)plastics and cadmium to physiology and biochemistry in parsley via a split-root system
Researchers used a split-root system to study how polystyrene micro- and nanoplastics interact with cadmium to affect parsley growth under conditions mimicking real-world uneven soil contamination. They found that cadmium was the primary driver of root damage and oxidative stress, but these effects remained localized to the contaminated side, suggesting the plant can isolate damage. Excessive nanoplastics combined with cadmium on both sides of the root system triggered defense mechanisms that altered the plant's production of beneficial bioactive compounds.
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.
Plant community responses to polypropylene microplastic and cadmium co-exposure: Implications for mycorrhizal strategies in a coastal wetland
Researchers conducted a mesocosm experiment to assess how polypropylene microplastics and cadmium interact in their effects on coastal wetland plant communities. They found that the combination of microplastics and heavy metals altered soil properties, plant community composition, and root traits in species-specific ways. The study suggests that mycorrhizal strategies play a role in how different plant species respond to this combined contamination.
Individual and Combined Effects of Nanoplastics and Cadmium on the Rhizosphere Bacterial Community of Sedum alfredii Hance
When polystyrene nanoplastics and cadmium co-occur in soil, they act synergistically to disrupt the bacterial community around plant roots (rhizosphere), reducing the diversity of beneficial bacteria by more than what either pollutant does alone. High concentrations of nanoplastics combined with cadmium significantly increased the availability of cadmium in soil by 4%, potentially increasing uptake by plants. This matters for both food safety — since Sedum alfredii is used in phytoremediation of heavy-metal-contaminated sites — and for understanding how combined pollution stresses affect soil health.
Effects of polyethylene microplastics on cadmium accumulation in Solanum nigrum L.: A study involving microbial communities and metabolomics profiles
This study found that polyethylene microplastics in soil reduced the ability of a plant known for cleaning up cadmium contamination to absorb the toxic metal. The microplastics changed the soil's microbial community and altered the plant's metabolism in ways that disrupted its natural heavy metal uptake process. This is important because it suggests microplastic pollution in farmland could interfere with natural and engineered soil cleanup strategies for heavy metals.
Assessing stress responses in potherb mustard (Brassica juncea var. multiceps) exposed to a synergy of microplastics and cadmium: Insights from physiology, oxidative damage, and metabolomics
Researchers found that microplastics in soil increased the amount of cadmium, a toxic heavy metal, that mustard green plants absorbed, while also reducing crop yields and photosynthesis. Higher concentrations of microplastics made more cadmium available in the soil, leading to greater accumulation of the metal in the plants. This raises food safety concerns because vegetables grown in microplastic-contaminated soil could contain higher levels of toxic metals that are harmful to human health.
Effects of cadmium contamination on bacterial and fungal communities in Panax ginseng-growing soil
Researchers examined how cadmium (a toxic heavy metal) contamination in soil affects the microbial communities around ginseng crops, finding that even low cadmium levels significantly disrupted bacterial diversity more than fungal diversity. Certain bacterial groups that tolerate cadmium became dominant, while beneficial microbes declined — changes that could affect soil health and ginseng safety.
Influence of cadmium and microplastics on physiological responses, ultrastructure and rhizosphere microbial community of duckweed
Researchers studied the combined effects of cadmium and polyethylene and polypropylene microplastics on duckweed, an aquatic plant. Interestingly, the study found that microplastics combined with cadmium actually reduced the heavy metal's toxicity to the plant compared to cadmium exposure alone, while also increasing the diversity of beneficial microbes in the root zone.
Ecotoxicological effects of polyethylene micro/nano-plastics and Cd on the physiological response, Cd migration, and their rhizosphere microbial community of Salix matsudana.
This study examined the combined ecotoxicological effects of polyethylene micro/nano-plastics and cadmium (Cd) on Salix matsudana, a willow with phytoremediation potential. Co-exposure altered the tree's physiological responses and Cd accumulation patterns, complicating its use for cleaning metal-contaminated soils.
Effects of combined microplastic and cadmium pollution on sorghum growth, Cd accumulation, and rhizosphere microbial functions
Researchers examined how different types and sizes of microplastics interact with cadmium, a toxic heavy metal, to affect sorghum growth and soil microbes. They found that the combined pollution generally increased plant stress and cadmium uptake, with effects varying by plastic type, particle size, and concentration. The study also revealed that the pollution mixture significantly altered soil bacterial communities and key metabolic pathways involved in nutrient cycling.
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.

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.
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.
