ClearInteracting 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.
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.
Impact of polystyrene nanoplastics (PSNPs) on seed germination and seedling growth of wheat (Triticum aestivum L.)
Researchers exposed wheat seeds and seedlings to polystyrene nanoplastics and found that while germination rates were unaffected, root growth increased significantly compared to controls. However, the nanoplastics were taken up by the roots and transported to the shoots, reducing micronutrient absorption and altering key metabolic pathways related to energy and amino acid production. The findings suggest that nanoplastics can fundamentally change how crop plants grow and process nutrients.
Polystyrene nanoplastics in soil impair drought priming-induced low temperature tolerance in wheat

Researchers grew radishes in soil contaminated with polystyrene nanoplastics and found that NP exposure reduced vegetable nutritional quality by lowering vitamin C, anthocyanin, and antioxidant content while increasing oxidative stress markers in the edible portions.

Researchers investigated how polystyrene microplastics of different sizes and concentrations affect seed germination of three ornamental plant species, finding that nanoscale particles at high concentrations significantly inhibited germination and early growth.
Species-dependent response of food crops to polystyrene nanoplastics and microplastics
Researchers exposed seeds of four common food crops to polystyrene nanoplastics and microplastics and found that the effects varied significantly depending on the plant species. Italian lettuce was the most sensitive, with germination rates dropping by up to 36%, while radish and wheat were largely unaffected. The study also found evidence that nanoplastics can be absorbed by plant roots within the first week of growth, raising questions about food safety implications.
Effect of Polystyrene Microplastics on Rice Seed Germination and Antioxidant Enzyme Activity
Researchers tested how different concentrations of polystyrene microplastics affect rice seed germination, root growth, and antioxidant enzyme activity. They found that at higher concentrations, the microplastics inhibited root growth and triggered oxidative stress responses in the seedlings. The study indicates that microplastic contamination in agricultural soils could interfere with early crop development, potentially affecting food production.
Investigating the Impact of Microplastics Type of Polyethylene, Polypropylene, and Polystyrene on Seed Germination and Early Growth of Rice Plants
Researchers investigated how three common types of microplastics, polyethylene, polypropylene, and polystyrene, affect rice seed germination and early seedling growth. They found that microplastic exposure altered root development and shoot growth, with the effects varying by polymer type. The study raises concerns about how microplastic-contaminated agricultural soils could affect staple crop establishment and food production.
Polystyrene Nanoplastics Compromise the Nutritional Value of Radish (Raphanus sativus L.)
Researchers found that polystyrene nanoplastics accumulated in radish roots and peels, reducing the vegetable's nutritional quality by disrupting its metabolism at the genetic level. When the contaminated radish was put through a simulated human digestion process, the nanoplastics were released and could potentially be absorbed by the body. This study shows how nanoplastics in soil can reduce the nutritional value of crops and create a direct route of human exposure through everyday vegetables.
Exploring the interaction between polystyrene nanoplastics and Allium cepa during germination: Internalization in root cells, induction of toxicity and oxidative stress
Researchers germinated onion seeds in the presence of 50 nm polystyrene nanoparticles and found that even the lowest dose caused cytotoxicity and genotoxicity in root meristem cells — including micronuclei formation — while fluorescence and electron microscopy confirmed that nanoparticles physically enter root cells and can potentially move up the food chain via crops.
Impacts of Micro/Nanoplastics Combined with Graphene Oxide on Lactuca sativa Seeds: Insights into Seedling Growth, Oxidative Stress, and Antioxidant Gene Expression
Researchers examined how polystyrene micro- and nanoplastics combined with graphene oxide affect lettuce seed germination and seedling growth. The combinations produced both harmful and protective effects depending on the specific measure being assessed, with oxidative stress being the primary mechanism of damage in roots and shoots. The study highlights the complexity of predicting how multiple nanomaterial pollutants interact in agricultural soils.
Physiological and biochemical effects of polystyrene micro/nano plastics on Arabidopsis thaliana
Experiments on the model plant Arabidopsis showed that polystyrene nano- and microplastics reduced seed germination, stunted growth, lowered chlorophyll levels, and triggered oxidative stress in roots, with smaller particles and higher concentrations causing the most damage. These findings raise concerns about how microplastic contamination in agricultural soil could affect crop health and ultimately food production.
The distribution and impact of polystyrene nanoplastics on cucumber plants
Researchers investigated how polystyrene nanoplastics of four different sizes distribute within cucumber plants and affect root growth and fruit quality. They found that smaller particles accumulated more readily throughout the plant, moving from roots to leaves and fruit, and caused greater disruption to root physiology. The study suggests that nanoplastic contamination in agricultural soils could affect both crop development and food quality.
Combined effects of micro/nanoplastics and ZnO nanoparticles on lactuca sativa seedlings under varied lighting
Researchers studied how polystyrene micro- and nanoplastics interact with zinc oxide nanoparticles to affect lettuce seed germination and early growth under different lighting conditions. They found that when the plastics were present alongside zinc oxide, the combined toxic effects were actually reduced compared to exposure to either contaminant alone. The study suggests that microplastics can alter how other engineered nanoparticles behave in agricultural settings, with lighting conditions playing an additional role.

Researchers tested the effects of polystyrene microplastics at different sizes and concentrations on pea seed germination and seedling growth in hydroponic experiments. They found that microplastics significantly harmed germination, with low concentrations of the smallest particles showing particularly notable effects. The study suggests that microplastic contamination in agricultural environments may pose risks to crop development even at relatively low concentrations.
