ClearNanoparticles in Plants: Uptake, Transport and Physiological Activity in Leaf and Root
This review examines how nanoparticles are absorbed and transported through plant roots and leaves, and how they affect plant growth and health. Understanding nanoparticle uptake by crops is important because similar mechanisms may apply to nanoplastics, meaning tiny plastic particles in soil could potentially enter the food supply through plants.
The review of nanoplastics in plants: Detection, analysis, uptake, migration and risk
This review examines how nanoplastics are detected, analyzed, taken up by plants, and migrate through plant tissues from roots to edible parts. As nanoplastics are found in agricultural soils, understanding how they enter food crops is critical for assessing human dietary exposure.
Uptake and transport of micro/nanoplastics in terrestrial plants: Detection, mechanisms, and influencing factors
This review summarizes how micro and nanoplastics enter and move through plants, including uptake through roots and leaves via processes like endocytosis and movement through cell walls. Smaller particles penetrate more easily, and factors like surface charge and soil conditions affect how much plastic plants absorb. The findings are important because they show that crops can take up microplastics from contaminated soil, creating a potential pathway for these particles to reach the human diet.
Uptake and Accumulation of Nano/Microplastics in Plants: A Critical Review
This review summarizes the latest research on how microplastics and nanoplastics are taken up by food crops through roots and leaves. Nanoplastics can penetrate plant cell walls more easily than larger microplastics, and the water-pulling force of transpiration is the main driver moving particles up through the plant. These findings are important for food safety because they confirm that plastic particles in contaminated soil can end up inside the fruits and vegetables people eat.
Fate of plastic nanoparticles (PNPs) in soil and plant systems: Current status & research gaps
This review examined the fate of plastic nanoparticles in soil and plant systems, highlighting how nanoparticles can be taken up by plant roots, translocated through tissues, and potentially enter the food chain, while identifying critical research gaps in toxicity assessment.
Polymer nanoparticles pass the plant interface
Researchers created well-defined fluorescent polymer nanoparticles and tracked their uptake into the roots and cells of Arabidopsis plants using microscopy. They found that smaller nanoparticles were taken up more efficiently than larger ones, with particles entering through the root system. The study provides direct evidence that nanoplastics can cross plant cell barriers, which has implications for understanding how plastic pollution may enter the food chain through crops.
How do nanoplastics hijack crop physiology: A review of uptake pathways and agricultural sustainability implications
This research review summarizes how tiny plastic particles called nanoplastics can get inside crop plants through their roots and leaves, potentially harming how plants grow and produce food. These ultra-small plastic pieces interfere with how plants absorb nutrients and respond to stress, which could threaten our food supply. Since we eat these crops, understanding how nanoplastics affect plant health is important for protecting both agriculture and human health.
Micro/nanoplastics: a potential threat to crops
This review examines micro- and nanoplastic contamination in agricultural soil and water, summarizing sources, adsorption onto microplastics, uptake pathways into crops, effects on plant growth and physiology, and current detection and removal approaches, while highlighting the limited data on nanoplastic transport in plants.
Bibliometric analysis and systematic review of the adherence, uptake, translocation, and reduction of micro/nanoplastics in terrestrial plants
This bibliometric analysis and systematic review synthesized research on how micro- and nanoplastics adhere to, are absorbed by, and translocate through terrestrial plants, with potential accumulation in edible tissues. The study found that particle size, surface charge, and plant species all influence uptake, and that current research lacks standardized methods, making it difficult to fully assess the risk of microplastics entering the human food chain through crops.
Uptake and translocation of nanoplastics in mono and dicot vegetables
Scientists exposed four different vegetable crops to fluorescent nanoplastics and tracked where the particles ended up in the plants. Nanoplastics were absorbed through the roots and transported to the stems and leaves of all plants tested, including tomatoes, radishes, and leafy greens. This confirms that food crops can take up nanoplastics from contaminated soil and deliver them to the parts of the plant that people eat.
Nanoplastic–plant interaction and implications for soil health
This review summarizes research on how nanoplastics interact with plants in soil environments, finding that these tiny particles can be taken up by roots and transported to all plant organs, including edible parts like grain. Researchers found that nanoplastics induce oxidative stress in plants, inhibiting photosynthesis and growth, and can also carry other soil pollutants into plant tissues. The study highlights significant concerns about nanoplastic contamination entering the food chain through agricultural crops.
Advances in transport and toxicity of nanoparticles in plants
Researchers reviewed how nanoparticles released into the environment are absorbed, transported, and accumulated by land plants, with evidence that they can stunt plant growth, damage cell structures, and cause DNA damage through oxidative stress. Because some of these plants are edible crops, nanoparticle contamination in soil poses a potential pathway for human health exposure.
Behavior of Microplastics and Nanoplasticsin Farmland Soil Environment and Mechanismsof Interaction with Plants
This review summarizes how microplastics and nanoplastics behave in farmland soil and how they interact with crop plants. Nanoplastics are especially concerning because they can travel through plant roots and move via internal transport systems to reach leaves, fruits, and even seeds. The review highlights that microplastic-contaminated soil could lead to plastic particles entering the human food chain through the crops we eat, though more long-term studies are needed to fully understand the risks.
Research Progress on the Mechanisms of Terrestrial Plant Uptake, Transport, and Growth Inhibition Responses to Micro (nano) Plastics
This review synthesizes current research on how terrestrial plants take up micro- and nanoplastics from contaminated soil, finding that particles can enter through roots, accumulate in plant tissues, block root function, and trigger oxidative damage that stunts growth. These pathways mean that food crops grown in microplastic-contaminated soils could expose humans to plastic particles through the diet, in addition to the harm caused to agricultural productivity.
[Progress on the Migration Mechanism and Toxic Effects of Nanoplastics in Terrestrial Plants].
This Chinese-language review paper synthesizes current knowledge on how nanoplastics — the smallest plastic particles — are absorbed and transported within land plants. Nanoplastics can enter plants through root surfaces, cell junctions, and leaf stomata, and once inside they impair growth, suppress photosynthesis, cause oxidative damage, and alter gene expression and metabolism. Because plants are a primary pathway through which nanoplastics could enter the human food chain, understanding their uptake mechanisms is directly relevant to food safety.
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.
