ClearSelenium alleviates the adverse effects of microplastics on kale by regulating photosynthesis, redox homeostasis, secondary metabolism and hormones
Researchers found that treating soil with selenium could protect kale plants from the harmful effects of microplastic contamination. Microplastics triggered damaging oxidative stress in the plants, but selenium helped restore the balance by boosting antioxidant defenses, improving photosynthesis, and regulating plant hormones. This suggests selenium supplementation could help maintain food crop health in microplastic-contaminated agricultural soils.

Researchers studied how zinc oxide nanoparticles applied to rice seeds could help the plants resist cadmium toxicity in contaminated soils. The study found that this seed treatment substantially improved early growth and strengthened the plants' biochemical defenses. These findings suggest a potential strategy for growing crops more safely in soils contaminated with heavy metals.

Dual-Stress Mitigation of Sclerotinia under Microplastic Toxicity by Nano-Selenium: Redox Balance, Pathogen Suppression, and Transcriptome Reprogramming
Researchers investigated whether selenium nanoparticles could protect rapeseed plants from combined stress caused by microplastics and the fungal pathogen Sclerotinia. The study found that selenium nanoparticles improved photosynthesis, reduced oxidative damage, and showed strong antifungal activity, suggesting they may help mitigate microplastic-induced phytotoxicity and fungal disease in agricultural settings.

Researchers tested whether selenium nanoparticles (SeNPs) could protect rapeseed plants from the combined stress of microplastic contamination and Sclerotinia sclerotiorum fungal infection. SeNPs improved seed germination, reduced oxidative damage, and altered gene expression to restore redox balance — largely reversing the dual stress effects.
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.
Mitigating the effects of PVC microplastics and mercury stress on rye (Secale cereale L.) plants using zinc oxide−nanoparticles
Researchers applied zinc oxide nanoparticles to rye plants exposed to PVC microplastics and mercury in soil, finding that ZnO-NPs mitigated some of the toxic effects by improving nutrient uptake and reducing oxidative stress. The study suggests nanoparticle-based approaches may help protect crops in microplastic- and heavy metal-contaminated soils.
ZnO Nanoparticle-based Seed Priming Modulates Early Growth and Enhances Physio-biochemical and Metabolic Profiles of Fragrant Rice Against Cadmium Toxicity
Researchers investigated whether priming fragrant rice seeds with ZnO nanoparticles could mitigate cadmium (Cd) toxicity during early seedling growth. They found that ZnO nanoparticle seed priming significantly improved seedling biomass and physiological attributes under Cd stress, though it had no significant effect on germination rate itself.

This review examines the potential of nano-selenium as an agricultural biostimulant, evaluating how selenium nanoparticles may improve crop productivity and seed germination while identifying research gaps in nano-enabled agriculture safety and efficacy.
How polystyrene nanoparticles and cadmium affect the growth, physiology, metabolic and ionomic profile of early-stage wheat seedlings individually and in combination
Researchers exposed two wheat cultivars to polystyrene nanoplastics and cadmium individually and in combination, finding the combined exposure caused the greatest oxidative stress, metabolic disruption, and ionomic imbalance, while one cultivar (HS-490) showed consistently better tolerance across all stress conditions.
Selenium-driven trophic restructuring of soil nematode communities and biochemical regulation alleviate the toxicity caused by microplastic pollution in highland barley
Researchers investigated whether selenium supplementation could counteract the harmful effects of polyethylene microplastics on highland barley and soil nematode communities. They found that microplastics significantly reduced plant growth metrics and disrupted nematode populations, but selenium application helped restore chlorophyll content, root development, and beneficial soil organism diversity. The study suggests that selenium may serve as a practical tool for mitigating microplastic-induced damage in agricultural soils.
Physiological and Cellular Ultrastructural Responses of Sesuvium portulacastrum under Cd Stress Grown Hydroponically
Researchers tested how the salt-tolerant plant Sesuvium portulacastrum responds to increasing concentrations of cadmium, a toxic heavy metal. The plant showed strong antioxidant defense mechanisms at lower cadmium levels but experienced significant cellular damage at higher concentrations, including disruption to chloroplasts and mitochondria. The findings suggest this species has moderate tolerance to heavy metal stress, which could make it useful for cleaning up contaminated environments.
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.
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.

Effect of cadmium and polystyrene nanoplastics on the growth, antioxidant content, ionome, and metabolism of dandelion seedlings
This study examined how polystyrene nanoplastics interact with cadmium, a toxic heavy metal, and found that the combination worsened the toxic effects on dandelion seedlings beyond what either pollutant caused alone.

Ecotoxicological Impacts of Microplastics and Cadmium Pollution on Wheat Seedlings
Researchers investigated the combined effects of polyethylene microplastics and cadmium on wheat seedlings and found that microplastics generally reduced the antioxidant enzyme response that cadmium alone would trigger. The study also found that microplastics altered cadmium bioaccumulation patterns, increasing cadmium uptake in roots at low concentrations but decreasing it at higher levels, suggesting complex interactions between these co-occurring pollutants.
Effect of cadmium on polystyrene transport in parsley roots planted in a split-root system and assessment of the combined toxic effects
Researchers used a split-root system to study how cadmium affects the movement of polystyrene micro and nanoplastics in parsley plants. They found that plastic nanoparticles traveled through the plant's internal transport system from contaminated roots to clean roots, but cadmium reduced this movement by changing the plastics' surface charge. The study shows that in contaminated soil, heavy metals and microplastics interact in complex ways that affect how much plastic ends up in edible crops.
