ClearReduced DNA methylation by Mn3O4 nanozyme protein corona formation improves cotton yield in saline land
Despite its title referencing nanoparticles and nanozymes, this paper studies how manganese oxide nanoparticles applied to cotton plant leaves improve crop growth and yield in salt-stressed soils — not microplastic pollution. It examines DNA methylation mechanisms and enzyme interactions in agricultural settings and is not relevant to microplastics or human health from plastic exposure.

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.
Polyethylene microplastic: impacts on ryegrass seed germination and seedling development
Researchers grew perennial ryegrass in hydroponic solution with polyethylene microplastics at six concentrations and three particle sizes (200 nm, 25 µm, 200 µm) and found that the smallest nanoparticles at the highest concentrations caused the greatest inhibition of germination, root growth, and seedling biomass.
Nanoparticles as catalysts of agricultural revolution: enhancing crop tolerance to abiotic stress: a review
This review looks at how nanoparticles can help crops withstand environmental stresses like drought, salt, and heavy metal contamination. While not directly about microplastics, the research is relevant because nanoparticles and microplastics share similar size ranges and behaviors in soil, and understanding how tiny particles interact with plants helps scientists assess both the risks and potential benefits of nanoscale materials in agriculture.
Effect of microplastics and nanoplastics on cereal crops
This review summarized how microplastics and nanoplastics in soil affect cereal crops including wheat, rice, and maize, finding that even small amounts can inhibit seed germination, reduce root growth, and impair nutrient uptake. Microplastic contamination of agricultural soils poses a direct threat to global food security.
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.
Effects of Microplastics on Germination and Seedlings Growth of Wheat (Triticum aestivum L.)
Researchers tested the effects of different microplastics on wheat seed germination and seedling growth and found that all treatments reduced plant development compared to controls. Polythene-containing microplastic treatments had the most negative impact, with significant reductions in both shoot and root length across wheat varieties.
Effect of microplastics on seed storage proteins of plants
This review examines how microplastic contamination affects plant seed storage proteins — key nutritional components and drivers of reproductive success — with implications for food security as MP-plant interactions increasingly challenge the foundation of agricultural food systems.
Comparative effect of silver nanoparticles on maize rhizoplane microbiome in initial phaseof plants growth
This is not about microplastics — it is a soil microbiology study examining how five different forms of silver nanoparticles with varying surface properties affect the bacterial and fungal communities in the root zone of maize seedlings.
Effect of Alumina Nanoparticles on Lentil Seed Germination Using Biospeckle Optical Coherence Tomography
Not a microplastics paper — this study uses optical coherence tomography to monitor how alumina nanoparticles of different sizes affect the internal biological activity of lentil seeds before germination, finding size-dependent effects on seed metabolic processes.
Biochemical Impact of Microplastic Exposure on Seed Enzyme Activation During Early Germination
This study examined how microplastic exposure affects antioxidant enzyme activity in seeds during early germination, finding that microplastics disrupted key biochemical processes required for seed activation. The results suggest soil microplastic contamination could impair crop establishment.
Promotion effect of nitrogen-doped functional carbon nanodots on the early growth stage of plants
Researchers found that nitrogen-doped carbon nanodots promoted seed germination, root growth, and biomass production across multiple plant species better than undoped nanodots. This is a plant science nanotechnology study not directly related to environmental microplastic pollution.
The Impact of Microplastic Concentration and Particle Size on the Germination and Seedling Growth of Pisum sativum L.
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.
Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review
Systematic review of 78 studies found that nano- and microplastics commonly cause adverse effects on plants even at environmentally relevant concentrations, with germination and root growth more strongly affected than shoot growth during early development. Chlorophyll levels were consistently reduced while stress indicators (ROS) and antioxidant enzymes were consistently upregulated across species.
[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.

Exposure of Bromus hordeaceus to fossil- and plant-based micro- and nanoplastics: Impacts and plant-plastic interactions vary depending on polymer type and growth phase
Experiments with the grass Bromus hordeaceus showed that both fossil-based polyethylene and plant-based PBAT micro- and nanoplastics affected seed germination and plant development, with polymer type and growth phase determining the nature and magnitude of effects.
Effects of microplastics on seed germination and seedling physiological characteristics of Spinacia oleracea under alkali stress.
Polystyrene nanoplastics at moderate to high concentrations (400 mg/L and above) inhibited spinach seed germination and suppressed antioxidant enzyme activity and chlorophyll levels, even under normal growing conditions. When combined with alkaline salt stress — simulating saline soils common in some agricultural regions — both stressors generally compounded harm to plant development. These findings raise concerns about microplastic contamination in irrigated croplands, where plants may already face chemical stress, potentially threatening food crop yields.
Effects of nano- & microplastics on terrestrial plants are ubiquitous and widespread: a systematic review
This systematic review finds that nano- and microplastics have widespread negative effects on plants, including reduced germination, stunted growth, and biochemical stress responses.
