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.

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.
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.

Integrated physiological, metabolomic, and transcriptomic responses of maize (Zea mays) and soybean (Glycine max) to nanoplastic-induced stress
Researchers exposed maize and soybean crops to polyethylene and polypropylene nanoplastics in soil and found that high concentrations suppressed plant growth and caused oxidative stress in both species. The nanoplastics accumulated in plant roots and disrupted normal gene activity and metabolism, with soybeans being more sensitive than maize. These findings raise concerns about food crop quality and safety as nanoplastic contamination of agricultural soil increases.
Multi-omics analysis reveals the molecular responses of Torreya grandis shoots to nanoplastic pollutant
Researchers used multi-omics analysis to examine how polystyrene nanoplastics affect Torreya grandis, an economically important tree species in China. They found that nanoplastic exposure disrupted the seedlings' metabolism and gene expression, particularly affecting pathways related to photosynthesis and stress responses. The study provides some of the first evidence that nanoplastic pollution can interfere with the molecular processes of higher terrestrial plants, not just aquatic organisms.
From single to combined stressors: Nanoplastic-ciprofloxacin synergy amplifies oxidative damage and metabolic dysregulation in Glycine max seedlings
When soybean seedlings were exposed to both nanoplastics and the antibiotic ciprofloxacin together, the combined stress was significantly worse than either pollutant alone, stunting growth and disrupting key metabolic processes in the leaves. The nanoplastics reduced root growth and plant size, while the antibiotic primarily damaged leaf function, and together they overwhelmed the plants' antioxidant defenses. This matters for food safety because soybeans are a major crop, and agricultural environments increasingly contain both nanoplastics and antibiotic residues.
