ClearInsight into the absorption and migration of polystyrene nanoplastics in Eichhornia crassipes and related photosynthetic responses
Researchers studied how water hyacinth plants absorb and transport polystyrene nanoplastics of different sizes. Smaller nanoplastics (20 nm) penetrated deeper into root tissue and migrated to leaves, while larger ones (200 nm) mostly stayed in the roots. Both sizes impaired photosynthesis, suggesting that nanoplastic pollution in waterways can harm aquatic plants that play important roles in water purification.
Tracing and trapping micro- and nanoplastics: Untapped mitigation potential of aquatic plants?
Researchers used fluorescently labeled polystyrene particles to trace microplastic and nanoplastic uptake in three aquatic plant species, finding that nanoplastics concentrated primarily in roots via apoplastic transport with bioconcentration factors up to 306, suggesting floating plants like water hyacinth may be useful for removing plastic from contaminated water.
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.
Translocation of polystyrene nanoplastics in distinct plant species: Novel insight from a split-root system and transcriptomic analysis
Researchers used a split-root system to study how polystyrene nanoplastics move through cucumber and maize plants, finding that the particles travel from roots to shoots via xylem and redistribute back to roots via phloem. Cucumber roots accumulated more nanoplastics than maize, while maize showed greater redistribution from shoots back to roots. The study revealed that aquaporin proteins play a key role in regulating nanoplastic uptake and transport in plants.
Phytoremediation of microplastics by water hyacinth
Researchers found that water hyacinth, a fast-growing floating plant, can remove 55-69% of microplastics from contaminated water within 48 hours through root adsorption. The plant's massive root surface area traps plastic particles, while a special structure in the stem prevents the plastics from reaching the leaves. This study offers a promising natural, low-cost approach to cleaning microplastics from waterways.
The threat of micro/nanoplastic to aquatic plants: current knowledge, gaps, and future perspectives
This review summarizes what is known about how micro- and nanoplastics affect aquatic plants, including how plants absorb these particles through roots and leaves and transport them internally. Exposure can alter plant growth, photosynthesis, and interactions with other organisms, though effects vary widely depending on plastic type and concentration. The authors highlight major research gaps and call for more studies on real-world conditions rather than controlled lab settings.
Uptake, transport and accumulation of micro- and nano-plastics in terrestrial plants and health risk associated with their transfer to food chain - A mini review.
This review examines how micro- and nano-plastics (MNPs) are taken up, transported, and accumulated in terrestrial plants, and assesses the associated health risks as MNPs transfer through the food chain from contaminated soil and water environments.
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.
Plant Uptake, Translocation and Metabolism of PBDEs in Plants
This review examined how flame retardant chemicals (PBDEs) from plastics accumulate in plants grown in contaminated soil, including through sewage sludge application to farmland. PBDEs are toxic additives found in many plastic products and can enter the food supply through plant uptake.
Accumulation modes and effects of differentially charged polystyrene nano/microplastics in water spinach (Ipomoea aquatica F.)
Researchers investigated how water spinach plants absorb nano and microplastics of different sizes and electrical charges. They found that smaller, positively charged particles were absorbed more readily by roots and could travel to the leaves, while larger particles tended to stay on root surfaces. This matters because leafy vegetables like water spinach could be delivering nanoplastics directly to people who eat them.
Can “Risk-Sharing” Mechanisms Help Clonal Aquatic Plants Mitigate the Stress of Nanoplastics?
This study examined how nanoplastics affect water hyacinth, a clonal aquatic plant that can share resources between connected parent and offspring plants. Nanoplastics accumulated in parent plants and transferred to offspring through connecting stems, reducing growth and damaging the photosynthetic system at all tested concentrations. The findings are concerning because aquatic plants used in ecological restoration could accumulate and spread nanoplastic contamination through water ecosystems.
Optimizing a controlled environment for microplastics uptake by aquatic plants
Researchers optimised experimental conditions for assessing microplastics uptake by aquatic plants, using polypropylene as a model polymer due to its lower-than-water density that causes particles to float at the water-air interface where many aquatic plants reside. Particle size distribution and composition were characterised using SEM, Raman spectroscopy, FTIR, optical microscopy, and laser diffraction across four water matrices.
Transport of Nanoparticles into Plants and Their Detection Methods
This review examines how nanoparticles enter plants through roots, leaves, and stems, and the methods scientists use to track them inside plant tissues. While focused broadly on nanoparticles used in agriculture and biotechnology, the findings are directly relevant to understanding how nanoplastics in soil and water can be taken up by food crops. The research highlights that particle size, charge, and coating all affect how readily nanoparticles penetrate plant barriers and accumulate in edible parts.
Mechanistic understanding on the uptake of micro-nano plastics by plants and its phytoremediation.
This review summarized the mechanisms by which micro-nano plastics are taken up by plants through roots and leaves, and evaluated the potential for phytoremediation as a strategy to reduce plastic contamination in soil, identifying key plant species and genetic factors that influence uptake.
Optimizing a controlled environment for microplastics uptake by aquatic plants
Researchers optimized controlled exposure conditions for studying microplastic uptake by aquatic plants, analyzing the dispersion behavior of polypropylene microparticles (chosen for their lower-than-water density) across different water matrices to better understand plant-microplastic interactions in aquatic ecosystems.
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.
Plant uptake, translocation and metabolism of PBDEs in plants of food and feed industry: A review
This review examines how polybrominated diphenyl ethers (PBDEs), flame retardant additives found in many plastic products, are taken up, translocated, and metabolized by food and feed crop plants. PBDEs can enter plants through soil and air, raising concerns about dietary exposure via contaminated agricultural produce.
Nanoparticles 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.
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.
Transport Dynamics and Physiological Responses of Polystyrene Nanoplastics in Pakchoi: Implications for Food Safety and Environmental Health
Researchers tracked fluorescently labeled nanoplastics as they traveled through pakchoi (a leafy green vegetable), entering through the roots, moving up through the plant's water-transport system, and accumulating in the leaves. The nanoplastics caused oxidative damage and disrupted plant hormones, demonstrating a clear pathway by which plastic pollution in soil could enter the human food supply through everyday vegetables.
