ClearInteractive 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.
The effects of multifactorial stress combination on rice and maize
This review examines how plants cope with multiple simultaneous environmental stresses — including drought, heat, flooding, and pollutants like microplastics — finding that combined stressors often cause more harm than individual stresses acting alone.
Microplastics meet invasive plants: Unraveling the ecological hazards to agroecosystems
This study examined how microplastic contamination in soil combines with invasive plant species to affect rice crops. The combination of both stressors caused greater changes in rice metabolism and antioxidant responses than either stressor alone. These findings highlight how microplastic pollution in agricultural soil can interact with other environmental challenges to threaten food safety and crop health.
Combined Inhibitory Effect of Canada Goldenrod Invasion and Soil Microplastics on Rice Growth
Researchers found that the combination of invasive Canada goldenrod plants and soil microplastics reduced rice biomass and disrupted antioxidant enzyme activity more severely than either stressor alone, suggesting that microplastic pollution can amplify the agricultural harm caused by invasive plant species.
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.
Polyvinyl chloride microplastics and drought co-exposure alter rice growth by affecting metabolomics and proteomics
Researchers investigated how PVC microplastics combined with drought stress affect rice growth using advanced protein and metabolite analysis. They found that both stressors individually harmed rice development, but together they caused even greater damage to plant metabolism and growth. The study reveals that microplastic contamination in agricultural soils may worsen the effects of drought on crop production.
The effect of microplastic pollution on rice growth, paddy soil properties, and greenhouse gas emissions: A global meta-analysis
This global meta-analysis of 40 studies found that microplastics reduce rice biomass by inducing oxidative stress and inhibiting photosynthesis, while depleting soil nitrogen, phosphorus, and organic carbon. Microplastics also stimulate nitrous oxide emissions from paddy soils, posing a dual threat to food security and climate through impaired rice production and increased greenhouse gas output.
High temperatures and microplastic enhanced inorganic phosphorus mineralization and phoD-harboring bacterial abundance in paddy soil
Researchers studied how microplastic contamination in rice paddy soil interacts with high temperatures to alter nutrient cycling and soil bacteria. They found that at normal temperatures microplastics reduced key soil nutrients, but at elevated temperatures the effect reversed, actually increasing nutrient availability and microbial diversity. The findings suggest that climate change could amplify the ways microplastics disrupt agricultural soil ecosystems.
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.
Combined effects of mulch film-derived microplastics and pesticides on soil microbial communities and element cycling
Researchers studied how microplastics from agricultural plastic mulch film interact with commonly used pesticides in cotton field soil. When present together, the pesticides had a stronger impact on soil bacteria than the microplastics alone, and the combination disrupted important nutrient cycling processes for carbon, nitrogen, and phosphorus. This matters because farmland contaminated with both microplastics and pesticides may experience compounding damage to soil health, ultimately affecting food production.
The effect of soil microplastics on Oryza sativa L. root growth traits under alien plant invasion
Researchers studied how microplastics in soil interact with an invasive weed species to affect rice root growth. Both stressors individually harmed rice roots, but their combination produced complex interactive effects that altered root architecture and nutrient uptake. This suggests that microplastic pollution in farmland may compound the damage caused by invasive plants, creating compounding threats to crop productivity.
Combined transcriptome and metabolome analysis revealed the toxicity mechanism of individual or combined of microplastic and salt stress on maize
Researchers studied how polystyrene microplastics combined with salt stress affect maize seedlings, finding that the combination reduced plant growth by nearly 74%, far worse than either stressor alone. Gene and metabolite analysis revealed that the combined stress severely disrupted energy production, antioxidant defenses, and hormone signaling in the plants. This is relevant to food security because microplastic-contaminated agricultural soils with high salt levels could dramatically reduce crop yields.
Co-exposure to microplastics and soil pollutants significantly exacerbates toxicity to crops: Insights from a global meta and machine-learning analysis
A large-scale analysis of 68 studies found that when microplastics combine with other soil pollutants, the harm to crops is significantly worse than from the other pollutants alone. Microplastics intensified damage to plant growth, increased oxidative stress, and reduced photosynthesis efficiency. Interestingly, microplastics did reduce the amount of other pollutants that accumulated in the crops, but the overall toxic effects on plant health were still greater.
Effect of combined salt and microplastic stress on the microbiota structure of the rice–oriental armyworm system
Researchers studied how salt stress and polyethylene microplastic contamination together affect rice plants and the insects that feed on them. They found that while individual stressors reduced insect weight, the combined stress surprisingly allowed partial recovery, suggesting complex interactions between the two environmental factors. The study reveals that co-occurring stresses from salt and microplastics reshape microbial communities in both plants and insects in unexpected ways.
Fate of nano/microplastics and associated toxic pollutants in paddy ecosystems: Current knowledge and future perspectives
Researchers reviewed how micro- and nanoplastics enter rice paddies through irrigation, mulch films, and atmospheric deposition, then harm soil health and rice plant growth by disrupting nutrient cycles and increasing oxidative stress. Their findings are especially significant because rice feeds more than half the world's population, yet research on plastic contamination in paddy systems remains very limited.
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.
Impacts of the coexistence of polystyrene microplastics and pesticide imidacloprid on soil nitrogen transformations and microbial communities
Researchers investigated the combined effects of polystyrene microplastics and the pesticide imidacloprid on soil nitrogen cycling and microbial communities over 28 days. They found that both pollutants individually and together significantly altered nitrogen transformation processes and shifted microbial community composition. The study suggests that the co-presence of microplastics and pesticides in agricultural soils can create compounding disruptions to essential nutrient cycling.
Combined effects of microplastics contamination and marine heatwaves on carbon cycling in coastal marine sediments
Researchers investigated the combined effects of microplastic contamination and marine heatwaves on carbon cycling processes in coastal marine sediments, examining how co-occurring stressors interact to alter microbial carbon processing. The study found that microplastics and elevated temperatures associated with marine heatwaves produced interactive effects on sediment carbon cycling, demonstrating that these two anthropogenic pressures cannot be adequately assessed in isolation.
Microplastic particles increase arsenic toxicity to rice seedlings
Researchers studied how polystyrene and polytetrafluoroethylene microplastics interact with arsenic to affect rice seedling growth. They found that microplastics alone reduced plant biomass and inhibited photosynthesis, while the combination with arsenic at higher concentrations amplified the toxic effects on root activity and cell membranes. The study reveals that microplastic contamination in agricultural settings may worsen the impact of other pollutants on food crops.
Single and combined effect of tetracycline and polyethylene microplastics on two drought contrasting cultivars of Oryza sativa L. (Rice) under drought stress
Researchers studied how the combination of the antibiotic tetracycline and polyethylene microplastics affects two rice varieties under drought conditions. They found that drought-resistant and drought-sensitive rice cultivars responded differently — the sensitive variety accumulated more of the antibiotic under drought stress. Metabolic analysis revealed that drought combined with these pollutants caused widespread disruption of plant metabolic processes, suggesting that climate stress and plastic pollution together may pose compounded risks to crop production.
