ClearTemperature 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.
Interactive impacts of heat stress and microplastics contamination on the growth and biochemical response of wheat (Triticum aestivum) and maize (Zea mays) plants
Researchers investigated how heat stress combined with polyethylene microplastic contamination in soil affects wheat and maize growth. They found that the combination significantly reduced plant height, root length, leaf area, and chlorophyll content more than either stressor alone. The findings highlight that microplastic pollution in agricultural soils could worsen the damage already caused by rising temperatures to food crops.

Researchers investigated how polystyrene nanoplastics in soil affect the cold stress tolerance of drought-primed wheat plants. The study found that nanoplastic contamination impaired the beneficial effects of drought priming on photosynthesis and carbohydrate metabolism, ultimately reducing grain yield, suggesting that nanoplastic pollution may undermine crop resilience strategies.
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.
Concurrence of microplastics and heat waves reduces rice yields and disturbs the agroecosystem nitrogen cycle
Researchers found that while microplastics or heat waves alone had mild effects on rice crops, the combination reduced yields by about 32% and significantly lowered grain protein and nutrient content. The dual stress disrupted nitrogen cycling in the soil and shifted nutrient distribution within the plants, reducing photosynthesis. This matters because climate change and plastic pollution are increasing simultaneously in agricultural regions.

Researchers tested how temperature increases combined with polystyrene nanoplastic exposure affect radish seed germination and early root growth under laboratory conditions. They found that 100- and 200-nanometer particles actually increased root growth, while temperature significantly affected germination rates, particularly at the highest nanoplastic concentrations. The study provides early evidence that climate change and nanoplastic pollution may interact in complex ways to affect crop development.

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.
Biological Responses to Climate Change and Nanoplastics Are Altered in Concert: Full-Factor Screening Reveals Effects of Multiple Stressors on Primary Producers
Using high-throughput screening of a freshwater green alga, researchers tested how nanoplastics interact with multiple climate change stressors (temperature, CO2, pH, UV), finding that nanoplastics combined with warming or UV caused greater harm than either alone, and that climate change will likely amplify nanoplastic toxicity.
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.
[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.
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.
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.
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.
The joint toxicity of polyethylene microplastic and phenanthrene to wheat seedlings
Researchers studied the individual and combined effects of polyethylene microplastics and the pollutant phenanthrene on wheat seedlings grown in soil. They found that microplastics alone caused dose-dependent reductions in plant growth and damaged the photosynthetic system, while the combination with phenanthrene worsened the damage. The study suggests that the co-occurrence of microplastics and organic pollutants in agricultural soils may create compounding negative effects on crop growth.
Integrating microplastic research in sustainable agriculture: Challenges and future directions for food production
Researchers reviewed how microplastics interact with environmental stressors like heat, drought, and salinity to threaten crop health and food safety, finding that microplastics can increase toxic metal uptake in plants and alter growth — with risks likely to worsen as climate change intensifies.
Effects of microplastics and salt single or combined stresses on growth and physiological responses of maize seedlings
Researchers studied how microplastics and salt stress, individually and combined, affect the growth of maize seedlings. They found that combined exposure caused more severe damage than either stressor alone, reducing plant biomass, disrupting photosynthesis, and increasing oxidative damage. The findings are relevant to agricultural regions where plastic mulch films break down into microplastics in salt-affected soils, creating compounding stress on crops.
Revealing the metabolomics and biometrics underlying phytotoxicity mechanisms for polystyrene nanoplastics and dibutyl phthalate in dandelion (Taraxacum officinale)
Researchers studied how polystyrene nanoplastics and a common plasticizer called dibutyl phthalate affect dandelion plants, both individually and in combination. They found that combined exposure significantly impaired plant growth, triggered oxidative stress, and disrupted key metabolic pathways more severely than either pollutant alone. The study suggests that the co-occurrence of nanoplastics and plastic additives in soil may pose compounding risks to plant health.
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.
Impact of nanopesticide CuO-NPs and nanofertilizer CeO2-NPs on wheat Triticum aestivum under global warming scenarios
Researchers exposed wheat to copper oxide nanopesticides and cerium oxide nanofertilizers under normal and elevated temperatures, finding that warming amplified the toxicity of both nanomaterials by disrupting root growth, nutrient uptake, and antioxidative pathways — underscoring the need to factor in climate change when assessing agricultural nanoparticle risks.
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.
Heatwaves increase the polystyrene nanoplastic-induced toxicity to marine diatoms through interfacial interaction regulation
Researchers found that marine heatwaves significantly worsen the toxic effects of polystyrene nanoplastics on an important ocean diatom species. The higher temperatures weakened the algal cell walls and increased nanoplastic adhesion, leading to greater membrane damage and reduced photosynthesis and carbon absorption. The findings suggest that climate change and plastic pollution together may pose a compounding threat to ocean productivity.

This study examined how elevated water temperatures — simulating marine heatwaves — amplify the toxicity of polystyrene nanoplastics in marine cells, finding that warming enhanced metabolic disruption caused by nanoplastics. The results suggest climate change and plastic pollution interact synergistically to harm marine organisms.
Do 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.
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.
