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.

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 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.

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.

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.

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.

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.

Microplastics alter cadmium accumulation in different soil-plant systems: Revealing the crucial roles of soil bacteria and metabolism

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.

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.

Responses of Sorghum Growth and Rhizosphere–Plastisphere Microbiomes to Cadmium and Polypropylene Microplastic Co-Contamination

Researchers examined how combined cadmium and polypropylene microplastic contamination affects sorghum growth and the bacterial communities in both rhizosphere soil and on the plastic surfaces. They found that co-contamination inhibited sorghum development more severely than either pollutant alone, and the bacterial community on the plastic surface was structurally simpler with lower diversity than in surrounding soil. The study suggests that microplastics in contaminated soils can serve as distinct microbial habitats that differ significantly from the native soil environment.

Coexistence of microplastics and Cd alters soil N transformation by affecting enzyme activity and ammonia oxidizer abundance

Researchers studied how the combined presence of microplastics and cadmium in soil affects nitrogen cycling, a process essential for soil fertility. They found that the pollutant mixture altered enzyme activity and shifted the balance of ammonia-oxidizing microbial communities more than either contaminant alone. The findings suggest that co-contamination of soils with microplastics and heavy metals could disrupt nutrient cycles critical for plant growth.

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.

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.
