ClearDo polystyrene nanoplastics affect the toxicity of cadmium to wheat (Triticum aestivum L.)?
Researchers investigated whether polystyrene nanoplastics affect the toxicity of cadmium to wheat plants. The study found that nanoplastics could alter how cadmium interacts with wheat, potentially modifying the uptake and toxic effects of the heavy metal, suggesting that the co-occurrence of nanoplastics and heavy metals in agricultural soils may create complex interactions affecting crop 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. The findings highlight that nanoplastics can change how heavy metals behave in the environment, potentially increasing the amount of toxic metals that enter the food chain through contaminated plants.
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.
Influence of soil microplastic contamination and cadmium toxicity on the growth, physiology, and root growth traits of Triticum aestivum L.
Researchers grew wheat plants in soil contaminated with polyethylene microplastics, the toxic heavy metal cadmium, or both, finding that combined exposure caused the worst damage — shrinking root area, reducing gas exchange in leaves, and lowering key growth indicators. These findings raise concerns about crop yields in farmland where plastic pollution and heavy metal contamination overlap, which is increasingly common.
Analyzing the impacts of cadmium alone and in co-existence with polypropylene microplastics on wheat growth
Researchers tested how cadmium and polypropylene microplastics individually and together affect wheat seedling growth, and found that their combined presence intensified negative effects on germination and early development. Cadmium alone inhibited root and shoot growth, and microplastics amplified this damage while also altering antioxidant enzyme activity in the plants. The study suggests that the co-occurrence of heavy metals and microplastics in agricultural soil may create compounding stress on crop health.
Mechanistic Insights into the Effects of Aged Polystyrene Nanoplastics on the Toxicity of Cadmium to Triticum Aestivum
This study examined how aged polystyrene nanoplastics interact with the heavy metal cadmium to affect wheat plants. Researchers found that the aging process increases the nanoplastics' ability to absorb cadmium, which can alter how the metal is taken up by crops, raising questions about combined contaminant exposure through the food supply.
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.
Temperature fluctuation in soil alters the nanoplastic sensitivity in wheat
Researchers simulated +4°C soil warming combined with polystyrene nanoplastic exposure in wheat seedlings and found the combination induced greater oxidative stress and reduced plant height, fresh weight, and net photosynthesis compared to either stressor alone, highlighting compounding risks from simultaneous nanoplastic pollution and climate warming on crop production.

Polystyrene nanoplastic contamination mixed with polycyclic aromatic hydrocarbons: Alleviation on gas exchange, water management, chlorophyll fluorescence and antioxidant capacity in wheat
Researchers investigated the combined effects of polystyrene nanoplastics and polycyclic aromatic hydrocarbons on wheat plants, finding that co-contamination disrupted gas exchange, water management, chlorophyll fluorescence, and antioxidant capacity more than either pollutant alone.
Interacting Effects of Heat and Nanoplastics Affect Wheat (Triticum turgidum L.) Seedling Growth and Physiology
Researchers exposed wheat seedlings to polystyrene nanoplastics under both normal (25°C) and elevated (35°C) temperature conditions to test whether heat stress and nanoplastic exposure interact to worsen plant health. They found that the combination of heat and nanoplastics caused greater oxidative stress and growth impairment than either stressor alone, suggesting that climate change could amplify the agricultural damage caused by nanoplastic pollution. This matters because global warming and plastic pollution are both worsening simultaneously, and crops are caught in the crossfire.
[Effects of Microplastics on the Growth, Physiology, and Biochemical Characteristics of Wheat (Triticum aestivum)].
Wheat seedlings were grown in soils spiked with 100 nm and 5 μm polystyrene microplastics, with high concentrations (200 mg/L) significantly inhibiting root and stem elongation, reducing chlorophyll, and altering antioxidant enzyme activity, with smaller nanoplastics showing greater toxicity. The findings demonstrate that microplastic size influences phytotoxicity in a major agricultural crop.
Antagonistic effect of polystyrene nanoplastics on cadmium toxicity to maize (Zea mays L.)
Researchers studied the combined effects of polystyrene nanoplastics and cadmium on maize plants and found that nanoplastics actually reduced cadmium toxicity. The study suggests that nanoplastics can adsorb cadmium and limit its uptake by plant roots, though both contaminants individually reduced plant growth and triggered oxidative stress responses.
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.
Comparison of the toxic effects of polystyrene and sulfonated polystyrene on wheat under cadmium stress
Researchers compared how regular polystyrene and chemically modified sulfonated polystyrene microplastics affect wheat plants exposed to cadmium contamination. Regular polystyrene actually helped protect wheat from cadmium damage, while the sulfonated version made things worse by increasing oxidative stress and disrupting key metabolic pathways. This study shows that different types of microplastics can have very different effects on crop health, and chemically modified plastics may pose greater risks to agriculture and food safety.
Polyethylene nanoplastics, tebuconazole and cadmium affect soil-wheat system by altering rhizosphere microenvironment under single or combined exposure
This study examined how polyethylene nanoplastics interact with a pesticide and cadmium (a toxic metal) in soil where wheat is grown. When all three pollutants were present together, they caused more damage to the soil ecosystem and wheat plants than any single pollutant alone. The findings are concerning because agricultural soils often contain multiple contaminants simultaneously, and their combined effects on crop safety and human food quality may be worse than expected.
Response of wheat (Triticum aestivum L. cv.) to the coexistence of micro-/nanoplastics and phthalate esters alters its growth environment
Researchers studied how wheat responds to co-existing stressors of microplastics and another soil contaminant, finding that combined exposure altered plant growth, physiological parameters, and grain quality compared to single-stressor exposures. The results highlight the importance of testing contaminant mixtures in agricultural soils.
Nanotoxicological effects and transcriptome mechanisms of wheat (Triticum aestivum L.) under stress of polystyrene nanoplastics
Researchers studied how polystyrene nanoplastics affect wheat plants at the molecular level using gene expression analysis. They found that nanoplastic exposure disrupted genes involved in photosynthesis, hormone signaling, and stress responses, ultimately reducing plant growth. The study provides new insights into how nanoplastic contamination in agricultural soils could harm crop development at a fundamental biological level.
Oxidative Damage in Roots of Rice (Oryza sativa L.) Seedlings Exposed to Microplastics or Combined with Cadmium
Rice seedlings exposed to polystyrene microplastics and cadmium showed combined toxic effects on root growth, fresh and dry weight, and antioxidant enzyme activities, with combined exposure producing greater oxidative damage than either pollutant alone. The study highlights synergistic phytotoxicity in a staple crop relevant to food security in microplastic-contaminated paddy soils.
The combined toxicity of polystyrene microplastic and arsenate: From the view of biochemical process in wheat seedlings (Triticum aestivum L.)
Researchers found that when wheat seedlings were exposed to both arsenic and polystyrene microplastics together, the microplastics reduced arsenic uptake in roots but dramatically increased arsenic transport to the above-ground parts of the plant — by up to 1,000%. This combined exposure caused more oxidative stress and damage to the plants' photosynthetic systems than arsenic alone. The findings suggest that microplastics in contaminated soil could increase how much toxic metal ends up in the edible parts of crops.
Joint toxicity of Cadmium (II) and microplastic leachates on wheat seed germination and seedling growth
This study tested how chemical leachates from PVC and LDPE microplastics interact with cadmium contamination to affect wheat crops. While certain combinations mildly boosted seed germination, the combination of cadmium and PVC leachates increased oxidative stress in seedlings, suggesting that microplastics in contaminated farm soils could make heavy metal toxicity worse for food crops. PVC leachate was more harmful than LDPE, underscoring that plastic type matters when assessing agricultural risk.
Effects of polystyrene microplastic on uptake and toxicity of copper and cadmium in hydroponic wheat seedlings (Triticum aestivum L.)
This study investigated how polystyrene microplastics interact with the heavy metals copper and cadmium in hydroponic wheat seedlings. Researchers found that while the microplastics alone did not significantly affect wheat growth, they adsorbed heavy metals and actually reduced the amount of copper and cadmium the plants absorbed. The findings suggest that in some cases microplastics may lessen heavy metal toxicity in plants by binding these metals and making them less available for uptake.
Joint toxicity of cadmium (II) and microplastic leachates on wheat seed germination and seedling growth
Researchers investigated how cadmium and chemical compounds that leach from microplastics jointly affect wheat seed germination and seedling growth. They found that microplastic leachates from PVC and polyethylene can interact with cadmium in complex ways, sometimes worsening and sometimes lessening the toxic effects on young wheat plants. The study suggests that the combined presence of heavy metals and microplastics in agricultural soils could pose risks to crop development.
Synergistic Effects of Polystyrene Nanoplastics and Cadmium on the Metabolic Processes and Their Accumulation in Hydroponically Grown Lettuce (Lactuca sativa)
When lettuce was grown with both nanoplastics and the toxic metal cadmium, the plants absorbed 61-67% more of both contaminants compared to exposure to either one alone. The combined pollution triggered a stronger stress response in the plants and changed how they grew. This is concerning for human health because it means nanoplastics in agricultural soil could significantly increase the amount of toxic heavy metals that end up in salad greens and other food crops.
