ClearPolystyreneNanoplastics Compromise the NutritionalValue of Radish (Raphanus sativus L.)
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.
Impact of Titanium Dioxide Nanoparticles on Agricultural Crops Performance: A Review of Efficacy and Mechanisms
This paper is not relevant to microplastics research; it reviews the effects of titanium dioxide nanoparticles on agricultural crop performance, focusing on photosynthesis enhancement and antimicrobial protection rather than plastic pollution.
Titanium dioxide nanoparticles alleviates polystyrene nanoplastics induced growth inhibition by modulating carbon and nitrogen metabolism via melatonin signaling in maize
Researchers found that titanium dioxide nanoparticles can help protect maize plants from the growth-inhibiting effects of polystyrene nanoplastics. The protective mechanism works through the plant hormone melatonin, which regulates carbon and nitrogen metabolism when the nanoparticles are present. The study suggests that certain nanoparticles could potentially be used as agricultural tools to help crops cope with nanoplastic contamination in soil.
PVC Inhibits Radish (Raphanus sativus L.) Seedling Growth by Interfering with Plant Hormone Signal Transduction and Phenylpropanoid Biosynthesis
Researchers found that PVC nanoplastics significantly inhibited radish seedling growth by disrupting plant hormone signaling and a key pathway involved in building cell walls. Using multiple analytical approaches, they showed that the nanoplastics caused oxidative stress, altered gene expression, and changed the plants' metabolic profiles. The study raises concerns about the overlooked toxicity of PVC agricultural mulch as it breaks down into tiny plastic particles in farm soils.
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.
Impact of nanoplastics uptake on modulation of plant metabolism and stress responses: a multi-omics perspective on remediation and tolerance mechanisms
Researchers reviewed how nanoplastics accumulate in plant tissues and disrupt metabolism, finding that these particles impair nutrient uptake, trigger reactive oxygen species overproduction, and alter gene and protein expression, while multi-omics approaches are revealing the molecular stress-response networks that plants use to tolerate or remediate nanoplastic contamination.

Titanium dioxide nanoparticles enhance the detrimental effect of polystyrene nanoplastics on cell and plant physiology of Vicia lens (L.) Coss. & Germ. seedlings
Combined exposure of Vicia lens seedlings to polystyrene nanoplastics and titanium dioxide nanoparticles caused greater physiological and cellular damage than either contaminant alone, suggesting synergistic toxicity at the plant level.
Micro and nanoplastics pollution: Sources, distribution, uptake in plants, toxicological effects, and innovative remediation strategies for environmental sustainability
This review examines how microplastics and nanoplastics enter plants through roots, disrupt growth and photosynthesis, and cause oxidative stress that reduces crop yields. Because these plastic particles can move through plant tissues and into edible parts, they represent a potential pathway for microplastics to enter the human food supply.
Transcriptomic and metabolomic changes in lettuce triggered by microplastics-stress
Researchers grew lettuce in water containing polystyrene microplastics and found that the particles accumulated in root tips and leaf veins, causing water loss stress and changes in gene expression. The plants responded by activating stress defense systems and altering their metabolism, including increased production of protective compounds in root secretions. This study provides molecular-level evidence that microplastics can stress food crops and change their biology, raising questions about the safety and nutritional quality of vegetables grown in contaminated environments.
Microplastic Pollution in Andisol: Effects on Soil Microbiology, Nitrogen Cycling, and Raphanus sativus L. Growth
Researchers assessed how polyamide, LDPE, and polypropylene microplastics affect Andisol soil properties and radish growth, finding microplastics reduced soil nitrogen cycling, disrupted microbial communities, and induced oxidative stress in plants — with effects varying by polymer type.
Rhizosphere nutrient dynamics and physiological responses of Oryza sativa L. under polyethylene terephthalate microplastic stress
Researchers exposed rice (Oryza sativa) to PET microplastics and found that the particles were absorbed by roots and translocated to aerial tissues, significantly inhibiting chlorophyll production, inducing oxidative stress (with malondialdehyde increasing by 175% at higher doses), and disrupting nitrogen, carbon, and phosphorus cycling genes in the rhizosphere.
Influence of polyethylene microplastics on Brassica rapa: Toxicity mechanism investigation
Researchers exposed the fast-growing plant Brassica rapa (related to turnip and cabbage) to polyethylene microplastics that had been degraded by sunlight, finding that the plastics stunted plant growth by up to 51% and triggered cellular stress responses. Genetic analysis revealed the microplastics disrupted the plant's immune and growth pathways, providing insight into how plastic pollution in agricultural soil could affect food crops.
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.

The study highlights risks to tea crop safety and quality from plastic pollution in agricultural soils.
Unveiling the impact of microplastics and nanoplastics on vascular plants: A cellular metabolomic and transcriptomic review
This review summarizes how microplastics and nanoplastics affect plant health at the cellular and genetic level, disrupting metabolism, nutrient uptake, and growth in vascular plants. Since contaminated crops are a pathway for microplastics to enter the human diet, understanding how plants absorb and respond to these particles is important for food safety.
Multi‐Omics Insights Into Phenylpropanoid and Lipid Barrier Biosynthesis in Maize Roots Under Salt and Microplastic Stresses
Researchers used transcriptomic and metabolomic analyses to investigate how polystyrene microplastics and salt stress — individually and in combination — affect phenylpropanoid and lipid barrier biosynthesis in maize seedling roots, finding that combined stresses alter molecular defence pathways in ways distinct from either stressor alone.
Effects of foliar microplastic exposure on cherry radish: Photosynthesis inhibition mechanisms and multi-omics functional network analysis
Researchers studied how foliar exposure to microplastics affects cherry radish plants and found that polystyrene microplastics reduced the net photosynthetic rate by over 63 percent. The microplastics blocked stomata, reduced mineral uptake needed for chlorophyll production, and caused oxidative stress in leaves and roots. The study reveals that airborne microplastics landing on plant surfaces can significantly impair crop growth through multiple interconnected mechanisms.
Mechanistic insights into the effects of micro- and nano-plastics on cherry radish physiology and organic compound distribution at the soil-root interface.
Researchers exposed cherry radish to polyethylene microplastics (2 µm) and nanoplastics (200 nm) at varying concentrations and measured effects on plant physiology and organic compound distribution at the soil-root interface. Smaller nanoplastic particles caused greater disruption to root exudate chemistry and plant metabolism than the larger microplastics, pointing to a size-dependent toxicity mechanism.
