ClearPotential impact of polyethylene microplastics on the growth of water spinach (Ipomoea aquatica F.): Endophyte and rhizosphere effects
Researchers studied how polyethylene microplastics affect the growth of water spinach, a widely consumed vegetable. The microplastics altered both the root-zone soil bacteria and the beneficial microbes living inside the plant, with effects varying by particle size. The study suggests that microplastic contamination in agricultural soil could indirectly affect crop health by disrupting the microbial communities plants depend on.
Lettuce seed germination in the presence of microplastic contamination
This study examined the effects of microplastic contamination on lettuce seed germination, finding that microplastics in soil altered physiological processes such as water retention and chlorophyll production, with implications for food safety and agricultural ecosystems.
The Effects of Microplastics and Heavy Metals Individually and in Combination on the Growth of Water Spinach (Ipomoea aquatic) and Rhizosphere Microorganisms
Researchers tested how combinations of microplastics and heavy metals (cadmium and lead) affect the growth of water spinach and the microbial communities in its root zone. They found that all three stressors individually inhibited plant growth, and combining microplastics with heavy metals intensified the toxic effects while reducing the availability of essential soil nutrients. The study suggests that microplastic-heavy metal interactions in agricultural soils may pose compounding risks to both crop health and soil ecosystem function.
Water Spinach (Ipomoea aquatica F.) Effectively Absorbs and Accumulates Microplastics at the Micron Level—A Study of the Co-Exposure to Microplastics with Varying Particle Sizes
Researchers discovered that water spinach plants can absorb and accumulate micron-sized polystyrene microplastics in their leaves when the particles are taken up through the roots. The plastic particles traveled from roots through the plant's transport system to accumulate in leaf tissue, and high concentrations stunted plant growth. This finding is directly concerning for food safety because it shows that leafy vegetables people eat can contain microplastics absorbed from contaminated soil or water.
Microplastics contamination on spinach (Spinacia oleracea): influence of plastic polymers, growing media, and copper co-exposure
A pot experiment tested how different microplastic polymers (LDPE, PBAT, starch-based) and copper co-contamination affected spinach grown in two soil types, finding that microplastic effects on plant growth and copper uptake varied significantly by polymer type and soil characteristics.
Effects of Microplastics on Growth and Physiological Characteristics of Tobacco (Nicotiana tabacum L.)
Researchers found that low-density polyethylene microplastics inhibited tobacco plant growth in hydroponics, with high concentrations (1,000 mg/L) reducing chlorophyll content, disrupting antioxidant defenses, and lowering overall biomass.
Effects of microplastics polluted soil on the growth of Solanum lycopersicum L.
This study tested how microplastic-contaminated soil affects tomato plant growth, finding that higher concentrations of plastic particles in soil reduced plant height, root development, and overall crop health. The results suggest that microplastic pollution in farmland could reduce food crop yields and potentially affect the quality of the produce we eat.
Effects of Soil Microplastics on Plant Growth and Soil Health
A greenhouse experiment found that polyethylene and polypropylene microplastics at increasing concentrations reduced lettuce biomass, altered soil microbial activity, and changed soil structure and water retention, with effects more pronounced at higher MP concentrations.
From the rhizosphere to plant fitness: Implications of microplastics soil pollution
Researchers exposed strawberry plants to low-density polyethylene microplastics in soil and found significant harm, including reduced chlorophyll levels, altered nutrient uptake, and increased stress responses. The microplastics also shifted the soil microbiome toward potentially harmful fungi and bacteria. These findings show that microplastics in agricultural soil can damage crop health and change the microbial community that plants depend on.
Effect of High-Density Polyethylene, Polyvinyl Chloride and Low-Density Polyethylene Microplastics on Seeding of Paddy
This study tested how three common types of plastic microparticles affect rice seedling growth, finding that they can interfere with early plant development. The results matter for food safety because rice is a staple crop for billions of people, and microplastic contamination in agricultural soil could affect crop yields and potentially introduce plastic particles into the food supply.
The effect of microplastic contaminated compost on the growth of rice seedlings
Researchers found that adding PET microplastics to compost significantly harmed rice seedling growth, reducing root length by 38%, plant height by 25%, and chlorophyll content by up to 55%. The microplastics appeared to interfere with nutrient uptake and photosynthesis. This is concerning because compost used in agriculture is often contaminated with plastic waste, which could reduce crop yields and potentially affect food quality.
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.
Polystyrene nanoplastics' accumulation in roots induces adverse physiological and molecular effects in water spinach Ipomoea aquatica Forsk
Researchers exposed water spinach to polystyrene nanoplastics in a hydroponic experiment and tracked where the particles accumulated in the plant. They found that nanoplastics built up primarily in the roots, causing reduced growth, impaired photosynthesis, and disrupted antioxidant defense systems. The study raises concerns about nanoplastic uptake by edible aquatic vegetables and the potential implications for food safety.
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.
Assessment of microplastic pollution on soil health and crop responses: Insights from dose-dependent pot experiments

Field soils showed measurable microplastic contamination, and pot experiments demonstrated dose-dependent effects on soil enzyme activity, water retention, and plant growth metrics.
Phytotoxicity of polystyrene, polyethylene and polypropylene microplastics on tomato (Lycopersicon esculentum L.)
Researchers tested the effects of polystyrene, polyethylene, and polypropylene microplastics on tomato plant growth using hydroponic experiments at various concentrations. The study found that all three types of microplastics negatively affected seed germination, root growth, and plant development, with effects varying by plastic type and concentration. These findings suggest that microplastic contamination in agricultural settings could interfere with crop growth and food production.
[Effect of Low-density Polyethylene Microplastics on Soybean-soil-microbial System].
A pot experiment explored how different concentrations of low-density polyethylene microplastics affect soybean plants, the soil they grow in, and the microbial communities in that soil. Higher microplastic concentrations inhibited soybean growth, reduced soil enzyme activity, and altered microbial diversity in ways that could impair soil fertility. As microplastic contamination of agricultural soils continues to grow, these findings suggest real risks to food crop productivity and soil ecosystem health.
Assessment of physiological stress on plants grown in soil contaminated with microplastics
Researchers tested how three types of microplastics (PET, HDPE, and polyester) affect the growth and health of spring onion and okra plants. They found that all microplastic types reduced chlorophyll levels, increased oxidative stress, and stunted plant growth, with HDPE and polyester causing the most damage. The study highlights the potential ecological risks microplastics pose to vegetable crops grown in contaminated soil.
