Clear[Effects of Polystyrene Microplastics on Growth, Physiology, Biochemistry, and Canopy Temperature Characteristics of Chinese Cabbage Pakchoi (Brassica chinensis L.)].
Hydroponic experiments showed that polystyrene microplastics at 100 nm and 1,000 nm sizes significantly inhibited the growth, photosynthesis, and nutrient quality of Chinese cabbage while increasing oxidative stress markers and elevating leaf temperature. These findings demonstrate that microplastic contamination poses a direct threat to crop production and food quality, with potential implications for human dietary exposure through contaminated vegetables.
[Effects of Polyethylene Microplastics on the Growth and Quality of Brassica campestris L. in a Three-season Consecutive Cultivation].
Researchers investigated how polystyrene microplastics of four particle size fractions (under 25, 25-48, 48-150, and 150-850 micrometers) affect the growth, development, and nutrient quality of Chinese cabbage (Brassica campestris L.) across three consecutive cultivation seasons in pot experiments, finding significant size-dependent inhibitory effects on plant growth and soil nutrient supply.
Influences of different source microplastics with different particle sizes and application rates on soil properties and growth of Chinese cabbage (Brassica chinensis L.)
Researchers tested how two types of microplastics at different sizes and concentrations affect soil properties and the growth of Chinese cabbage. They found that smaller particles at higher concentrations altered soil enzyme activity and reduced plant growth, though the effects depended on the specific plastic type. The study suggests that microplastic contamination in agricultural soils could meaningfully impact crop productivity and soil health.
Effects of Different Mulch Types on Farmland Soil Moisture in an Artificial Oasis Area
Not relevant to microplastics — this study compares how different mulch materials (including conventional polyethylene plastic films) affect soil moisture retention in an arid farming region of China, focusing on water management rather than plastic fragmentation or microplastic contamination.
The toxicological effect on pak choi of co-exposure to degradable and non-degradable microplastics with oxytetracycline in the soil
This study tested how microplastics and the antibiotic oxytetracycline, both common contaminants in farmland soil, affect pak choi (a leafy vegetable). Both types of microplastics harmed root growth, photosynthesis, and plant metabolism, and surprisingly, biodegradable PLA microplastics caused more damage than conventional polyethylene ones. The findings suggest that microplastic contamination in agricultural soil could reduce crop quality and nutritional value, with so-called eco-friendly plastics potentially being worse for plants.
Natural Aging Intensifies Microplastic Phytotoxicity in Brassica chinensis
Researchers compared the effects of pristine and naturally aged polyethylene and polystyrene microplastics on Chinese cabbage growth and soil health over a 45-day experiment. They found that aged microplastics with oxidized surfaces caused significantly more plant damage, reducing biomass and chlorophyll content more than their pristine counterparts. The study suggests that as microplastics weather in agricultural soils, they may become increasingly harmful to crops.
Stress of polyethylene and polylactic acid microplastics on pakchoi（Brassica rapa subsp. chinensis） and soil bacteria: Biochar mitigation
Researchers compared the effects of conventional polyethylene and biodegradable polylactic acid microplastics on pakchoi (a leafy vegetable) and found that both types harmed plant growth and disrupted soil bacteria. Adding biochar to the soil helped reduce these negative effects, suggesting it could be a practical way to protect crops from microplastic contamination in agricultural settings.
Natural Aging IntensifiesMicroplastic Phytotoxicityin Brassica chinensis
Researchers compared pristine and artificially aged polyethylene and polystyrene microplastics applied to pak choi (Brassica chinensis) in soil over 45 days. Aged MPs with oxidised surfaces caused stronger phytotoxicity than pristine MPs, reducing plant biomass and disrupting soil enzyme activity, demonstrating that environmental weathering worsens MP impacts on crops.
The effects of microplastics on crop variation depend on polymer types and their interactions with soil nutrient availability and weed competition
Researchers investigated how different types of microplastics interact with soil nutrient availability and weed competition to affect crop growth. The study found that the effects of microplastics on plant performance depend on the polymer type and are modulated by fertilization levels and competition from weeds, suggesting that real-world agricultural impacts of microplastic pollution may be more complex than laboratory studies indicate.
Microplastic pollution in organic farming development cannot be ignored in China: Perspective of commercial organic fertilizer
Researchers found that commercial organic fertilizers used across China contain high levels of microplastics, ranging from thousands to tens of thousands of particles per kilogram, with most being very small particles under 100 micrometers. After five years of fertilizer application, enormous quantities of microplastics are predicted to accumulate in orchard soils. This means that organic farming, often considered the healthier choice, may actually be introducing significant microplastic contamination into food-producing soil.
Single and combined effect of polyethylene microplastics (virgin and naturally aged) and cadmium on pakchoi (Brassica rapa subsp. chinensis) under different growth stages
Researchers examined the single and combined effects of polyethylene microplastics and cadmium on pakchoi vegetables at different growth stages. The study found that naturally aged microplastics had different effects than virgin ones, and that the combination of microplastics and cadmium could worsen oxidative stress and nutrient disruption in plants, particularly during early growth.
Effects of composite microplastics on soil properties and the physiological and biochemical characteristics of Chinese cabbage
A pot experiment exposing Chinese cabbage to combinations of polyethylene, polypropylene, PVC, and polyolefin microplastics found that composite microplastic mixtures altered soil properties and disrupted plant physiological and biochemical processes more than individual plastics alone.
[Effect of Organic Fertilizers on the Accumulation and Distribution of Polystyrene Nanoplastics in Cotton Plants].
This pot experiment found that cotton plants absorb polystyrene nanoplastics through their roots and transport them into stems, but adding organic fertilizer reduced the amount transferred upward, with most nanoplastics retained in roots. While nanoplastics alone reduced plant growth indicators, organic fertilizer partially offset these negative effects. The results suggest that organic soil amendments could help reduce the uptake and spread of nanoplastics in food crops, which has implications for agricultural food safety.
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.
Biodegradable microplastics reduce the effectiveness of biofertilizers by altering rhizospheric microecological functions
Researchers found that biodegradable microplastics from PBAT mulch films significantly reduced the growth-promoting effects of biofertilizers on Chinese cabbage, cutting above-ground biomass by up to 53%. The microplastics altered soil enzyme activity, increased organic carbon levels, and reshaped the bacterial communities in the root zone. The study suggests that accumulation of biodegradable plastic residues in agricultural soils could undermine the effectiveness of biofertilizer-based farming strategies.
Unveiling the effect of microplastics on agricultural crops – a review
This review examines how microplastics affect agricultural crops, covering impacts on seed germination, root growth, photosynthesis, and overall plant health. Most studies focused on polystyrene and polyethylene under controlled lab conditions, and the effects varied widely depending on plastic type, size, and concentration. The authors stress that more field-based research is needed to understand how microplastics actually behave in real farming environments.
Micro/Nanoplastics in plantation agricultural products: behavior process, phytotoxicity under biotic and abiotic stresses, and controlling strategies
This review examines how microplastics and nanoplastics from sources like plastic mulch and wastewater contaminate agricultural crops, harming plant growth, photosynthesis, and food quality. The findings matter for human health because these plastic particles can accumulate in the fruits and vegetables we eat, carrying toxic chemicals along with them into our diet.
Effects of Organic Fertilizer Mixed with Food Waste Dry Powder on the Growth of Chinese Cabbage Seedlings
Adding food waste dry powder to bio-fertilizer mixtures at 30% concentration was tested on Chinese cabbage seedlings. Results showed effects on growth, chlorophyll, and mineral content, with implications for sustainable use of food waste in agriculture.
Novel insights related to soil microplastic abundance and vegetable microplastic contamination
Researchers analyzed microplastic contamination in farmland soils and the vegetables grown in them, finding that polyethylene and polypropylene were the most common plastic types in soil. Chinese cabbage had the highest vegetable contamination levels, and there was a moderate correlation between soil and vegetable microplastic concentrations. The study provides real-world evidence that microplastics in agricultural soil can transfer into the food crops people eat.
Occurrence and distribution of microplastics in organic fertilizers in China
Researchers surveyed microplastic contamination in organic fertilizers across China, finding widespread plastic particles in compost, manure, and biosolids, identifying fertilizer application as an emerging pathway for microplastic accumulation in agricultural soils.
Transport Dynamicsand Physiological Responses ofPolystyrene Nanoplastics in Pakchoi: Implications for Food Safetyand Environmental Health
Researchers tracked the transport and physiological responses of polystyrene nanoplastics in pakchoi (bok choy) plants, finding that nanoplastics were absorbed through roots and translocated to shoots where they disrupted chlorophyll production and reduced plant growth.
Effects of different mulch materials on the photosynthetic characteristics, yield, and soil water use efficiency of wheat in Loess tableland
Not relevant to microplastics — this agricultural study compares different mulching materials (including plastic film) on wheat yield and water use efficiency in the Loess Plateau of China, with no focus on microplastic pollution from plastic mulch.
Physiological responses of lettuce (Lactuca sativa L.) to microplastic pollution
PVC microplastics of two different size ranges had contrasting effects on lettuce roots, with smaller particles stimulating root growth and larger particles having no effect, and smaller particles also reduced photosynthetic efficiency at moderate concentrations. The study suggests that microplastic size is a key variable determining whether effects on crops are stimulatory or inhibitory.
Multifaceted effects of microplastics on soil-plant systems: Exploring the role of particle type and plant species
Researchers tested how three different types of microplastics — fibers, fragments, and spheres — affect soil properties and vegetable growth. The effects varied significantly depending on both the type of plastic and the plant species, with some microplastics actually promoting root growth in certain vegetables. These mixed results highlight that the impact of microplastic contamination on food crops is complex and depends on the specific conditions in each field.
