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.

Assessing the interactive effects of microplastics and acid rain on cadmium toxicity in rice seedlings: Insights from physiological and transcriptomic analyses
Researchers studied how the combination of microplastics, acid rain, and cadmium affects rice seedling growth. They found that at high cadmium concentrations, the presence of microplastics and acid rain actually reduced cadmium's toxic effects by lowering how much of the metal accumulated in the plants. The study provides nuanced evidence that interactions between multiple environmental pollutants can sometimes produce unexpected outcomes, which matters for understanding food safety in contaminated agricultural areas.
Plant growth-promoting bacteria modulate gene expression and induce antioxidant tolerance to alleviate synergistic toxicity from combined microplastic and Cd pollution in sorghum
Scientists found that a beneficial soil bacterium (Bacillus sp. SL-413) can help protect sorghum plants from the combined toxic effects of microplastics and cadmium, a heavy metal. The bacterium boosted plant growth, reduced harmful reactive oxygen species by up to 27%, and reactivated genes that the pollution had shut down. This research points to a nature-based solution for helping food crops survive in microplastic-contaminated soil.

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 Cadmium Stress on Carbon Sequestration and Oxygen Release Characteristics in A Landscaping Hyperaccumulator—Lonicera japonica Thunb.
This study examines how cadmium stress affects the growth, photosynthesis, and carbon sequestration capacity of the landscape plant Lonicera japonica. It is not about microplastics and is not relevant to microplastic research.
Phenotypic and transcriptomic shifts in roots and leaves of rice under the joint stress from microplastic and arsenic
This study examined how rice plants respond when exposed to both microplastics and heavy metal cadmium at the same time. Researchers found that the combination caused distinct changes in root and leaf gene expression and growth patterns compared to either pollutant alone. The findings suggest that microplastics may alter how plants take up and respond to heavy metals, potentially affecting crop safety.
Preliminary Analysis of the Salt-Tolerance Mechanisms of Different Varieties of Dandelion (Taraxacum mongolicum Hand.-Mazz.) Under Salt Stress

It examines transcriptomic and metabolomic changes under salt conditions and is not relevant to microplastics or human health.
Revealing the Selenium-Mediated Regulatory Mechanisms of P. stratiotes in Response to Nanoplastics Stress from Multiple Perspectives of Transcriptomics, Metabolomics, and Plant Physiology
Scientists found that tiny plastic particles (nanoplastics) seriously damage water plants by disrupting their ability to make food from sunlight and causing harmful stress inside their cells. However, when researchers added selenium (a natural mineral) to the water, it helped protect the plants from plastic damage by boosting their natural defense systems. This research could help us clean up plastic pollution in lakes and rivers, which is important since these water sources can affect human health through drinking water and food chains.
Transcriptomics, proteomics, and metabolomics interventions prompt crop improvement against metal(loid) toxicity
This review examines how advanced molecular analysis tools -- transcriptomics, proteomics, and metabolomics -- are helping scientists understand how plants respond to toxic metals in contaminated soil. While focused on metal toxicity rather than microplastics directly, these same tools are being used to study how microplastics interact with heavy metals to create combined threats to crop safety and human 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.
Euphorbia marginata Alleviate Heavy Metal Ni-Cu Combined Stress by Regulating the Synthesis of Signaling Factors and Flavonoid Organisms
Despite its title referencing heavy metal stress in plants, this paper studies how the ornamental plant Euphorbia marginata responds physiologically and genetically to copper and nickel contamination in soil — not microplastic pollution. It examines antioxidant responses, cell membrane damage, and gene expression related to phytoremediation of heavy metals and is not relevant to microplastics or human health from plastic exposure.
Polystyrene nanoplastics distinctly impact cadmium uptake and toxicity in Arabidopsis thaliana
In a study using the model plant Arabidopsis, polystyrene nanoplastics increased the uptake and accumulation of the toxic heavy metal cadmium in plant roots. The combined stress of nanoplastics and cadmium caused worse oxidative damage and growth problems than either pollutant alone. This is concerning because it means microplastics in agricultural soil could help toxic metals get into crops more easily, potentially increasing human exposure through food.
