ClearToxicity of polyvinyl chloride microplastics on Brassica rapa
Researchers exposed Brassica rapa plants to UV-weathered PVC microplastics and found significant growth inhibition, with stem length reduced by nearly 46% and root length by 35% after 30 days. The microplastic particles blocked leaf stomata and were observed entering the plant tissue, triggering stress responses including increased enzyme activity. The study suggests that microplastics in soil can physically and chemically interfere with normal plant development.
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.
Inhibition of Peanut(Arachis hypogaea L.) Growth, Development,and Promotion of Root Nodulation IncludingPlant Nitrogen Uptake Triggered by Polyvinyl Chloride Microplastics
Researchers investigated the impact of polyvinyl chloride (PVC) microplastics at concentrations of 0.5%, 1.5%, 2.5%, and 3.5% on peanut (Arachis hypogaea L.) growth, development, root nodulation, and nitrogen uptake. They found that PVC microplastics inhibited above-ground plant growth while promoting root nodule formation, indicating that soil microplastic contamination can disrupt plant physiology and nitrogen cycling in agricultural systems.
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.
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.
Inhibition of Peanut (Arachis hypogaea L.) Growth, Development, and Promotion of Root Nodulation Including Plant Nitrogen Uptake Triggered by Polyvinyl Chloride Microplastics
Researchers investigated the impact of polyvinyl chloride (PVC) microplastics at four dosages (0.5%, 1.5%, 2.5%, and 3.5%) on the growth, development, root nodulation, and nitrogen uptake of peanut (Arachis hypogaea L.) plants. They found that PVC microplastics inhibited plant growth and development while paradoxically promoting root nodulation, suggesting complex soil-plant-microbiome interactions that could have implications for nitrogen cycling and food security in contaminated agricultural soils.
Toxicity of photoaged polyvinyl chloride microplastics to wheat seedling roots
Sunlight-aged PVC microplastics were found to be more toxic to wheat seedling roots than fresh PVC particles, with the aged particles stunting root growth by up to 7.5%. The toxicity came from both physical damage caused by smaller broken-down particles and chemical harm from additives that leached out of the aging plastic. This research matters because PVC is one of the most common microplastics in farm soil, and its increasing toxicity with age could affect crop health and food production.
PolystyreneNanoplastics 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.
Physiological responses of garden cress (L. sativum) to different types of microplastics
Researchers tested the effects of four common types of microplastics on garden cress plants and found that PVC was the most toxic, causing the greatest oxidative stress and growth inhibition. Both acute and chronic exposure to microplastics affected seed germination, plant height, biomass, and levels of stress-response compounds in the plants. This is one of the first studies to demonstrate that microplastics can trigger oxidative damage in terrestrial plants, with implications for agricultural ecosystems.
Impact of polyvinyl chloride (PVC) microplastic on growth, photosynthesis and nutrient uptake of Solanum lycopersicum L. (Tomato)
Adding PVC microplastics to soil reduced tomato plant growth, photosynthesis, and nutrient uptake in a dose-dependent manner, even though no visible damage appeared on the leaves. At the molecular level, the microplastics disrupted genes and proteins involved in photosynthesis and nutrient absorption. This matters for food safety because microplastics in agricultural soils could reduce crop yields and potentially enter the food supply.
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.
Impacts of Plastics on Plant Development: Recent Advances and Future Research Directions
This review summarizes how microplastics and nanoplastics affect plant growth, from blocking seed germination and root development to causing oxidative stress and DNA damage in plant cells. Nanoplastics are small enough to be absorbed by roots and transported to stems, leaves, and even fruits. These findings are concerning for human health because they show that microplastics can enter the food supply through crops, creating a direct pathway for human exposure through plant-based foods.
Unraveling the impact of nano-microscale polyethylene and polypropylene plastics on Nicotiana tabacum: Physiological responses and molecular mechanisms
Researchers exposed tobacco plants to polyethylene and polypropylene microplastics of different sizes and found that both types suppressed plant growth in a dose-dependent manner, with polypropylene being more toxic. The microplastics disrupted photosynthesis, triggered oxidative stress, and altered hormone signaling and defense pathways in the plants. These findings demonstrate that microplastic contamination in soil can impair crop growth at the molecular level, potentially affecting agricultural productivity.
Toxic Impact of Soil Microplastics (PVC) on Two Weeds: Changes in Growth, Phenology and Photosynthesis Efficiency
Researchers found that PVC microplastics in soil negatively affected growth, photosynthetic efficiency, and phenological timing in two weed species, with effects varying by concentration and plant species, suggesting that soil microplastic contamination can alter plant community dynamics in agricultural and natural ecosystems.
Impact of microplastics on growth, photosynthesis and essential elements in Cucurbita pepo L.
Researchers grew squash plants in soil contaminated with four common types of microplastics and found that all four impaired plant growth, especially in the shoots and leaves. PVC was the most toxic, reducing leaf size, photosynthesis, and iron uptake more than the other plastic types. These findings raise concerns that microplastic-contaminated agricultural soil could reduce crop yields and potentially introduce plastics into the food chain.
Assessing the impact of micro and nanoplastics on the productivity of vegetable crops in terrestrial horticulture: a comprehensive review
This review summarizes research on how micro and nanoplastics accumulate in farmland and get absorbed by vegetable crops through their roots, building up in the edible parts of the plants. The plastic particles cause toxic effects that stunt plant growth by disrupting cellular processes and gene activity. This means the vegetables people eat may contain microplastics picked up from contaminated soil.
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.
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.
Responses of maize (Zea mays L.) seedlings growth and physiological traits triggered by polyvinyl chloride microplastics is dominated by soil available nitrogen
Researchers found that PVC microplastics in soil reduced maize seedling growth primarily by depleting available nitrogen, a nutrient essential for plant development. The microplastics altered soil bacteria, enzymes, and nutrient levels, with nitrogen availability explaining nearly 88% of the changes in plant growth. This suggests that microplastic pollution in agricultural soil could reduce crop yields by starving plants of essential nutrients.
Polyethylene microplastic modulates lettuce root exudates and induces oxidative damage under prolonged hydroponic exposure
Researchers grew lettuce in water containing polyethylene microplastics for 28 days and found that the plastics changed the chemical signals the roots released and caused oxidative damage in the leaves. While the plants looked mostly normal on the outside, the microplastics altered the root chemistry in ways that could affect nutrient uptake and plant defense. This is relevant to human health because lettuce is widely consumed and may be grown in microplastic-contaminated water or soil.
Physiological analysis and transcriptome profiling reveals the impact of microplastic on melon (Cucumis melo L.) seed germination and seedling growth
Researchers examined how polyvinyl chloride microplastics affect melon seed germination and seedling development. They found that low to medium concentrations of microplastics significantly reduced germination rates and stunted young root growth, while also disrupting gene expression related to plant stress responses. The study provides early evidence that microplastic contamination in agricultural soils may impair the growth of economically important crop plants.
Biochar-derived dissolved and particulate matter effects on the phytotoxicity of polyvinyl chloride nanoplastics
Researchers investigated how dissolved and particulate matter released from biochar affects the toxicity of PVC nanoplastics to lettuce plants. They found that biochar-derived dissolved matter reduced nanoplastic toxicity by coating the plastic particles and limiting their uptake by roots, while particulate matter had a more complex effect. The study helps explain why biochar can protect plants from nanoplastic damage and provides insight into developing soil amendments for contaminated agricultural land.
Morphological, physiological, and molecular responses of Perilla frutescens to copper stress alleviated by PVC microplastics
Researchers discovered that low concentrations of PVC microplastics can actually reduce the harmful effects of copper on perilla plants, an important crop. The microplastics appeared to help by improving cell membrane function, suppressing stress hormones, and adjusting fat metabolism pathways. While this does not mean microplastics are beneficial overall, the study reveals surprisingly complex interactions between plastic pollution and heavy metals in agricultural environments.
