ClearMicroplastics meet invasive plants: Unraveling the ecological hazards to agroecosystems
This study examined how microplastic contamination in soil combines with invasive plant species to affect rice crops. The combination of both stressors caused greater changes in rice metabolism and antioxidant responses than either stressor alone. These findings highlight how microplastic pollution in agricultural soil can interact with other environmental challenges to threaten food safety and crop health.
Combined Inhibitory Effect of Canada Goldenrod Invasion and Soil Microplastics on Rice Growth
Researchers found that the combination of invasive Canada goldenrod plants and soil microplastics reduced rice biomass and disrupted antioxidant enzyme activity more severely than either stressor alone, suggesting that microplastic pollution can amplify the agricultural harm caused by invasive plant species.
Combined Impact of Canada Goldenrod Invasion and Soil Microplastic Contamination on Seed Germination and Root Development of Wheat: Evaluating the Legacy of Toxicity
Researchers studied the combined effects of invasive Canada goldenrod and microplastic contamination on wheat seed germination and root growth. They found that both stressors individually and together impaired wheat development, with their combined impact being particularly concerning for agricultural productivity. The study highlights how multiple environmental stressors can interact to compound threats to food crops.
Phenotypic and transcriptomic shifts in roots and leaves of rice under the joint stress from microplastic and arsenic
This study examined how rice plants respond when exposed to both microplastics and heavy metal cadmium at the same time. Researchers found that the combination caused distinct changes in root and leaf gene expression and growth patterns compared to either pollutant alone. The findings suggest that microplastics may alter how plants take up and respond to heavy metals, potentially affecting crop safety.
Microplastics and Invasive Alien Plants: A Change in Soil Ecology Deliberately Impacts the Aboveground Productivity of the Crops
This study examines how microplastic contamination and invasive plant species can jointly harm crop productivity and soil health. Evidence indicates that when both stressors are present in farmland, they significantly disrupt soil carbon cycling, microbial activity, and plant growth, creating a compounding problem that may indirectly affect food safety.
Polyvinyl chloride microplastics and drought co-exposure alter rice growth by affecting metabolomics and proteomics
Researchers investigated how PVC microplastics combined with drought stress affect rice growth using advanced protein and metabolite analysis. They found that both stressors individually harmed rice development, but together they caused even greater damage to plant metabolism and growth. The study reveals that microplastic contamination in agricultural soils may worsen the effects of drought on crop production.
The effects of multifactorial stress combination on rice and maize
This review examines how plants cope with multiple simultaneous environmental stresses — including drought, heat, flooding, and pollutants like microplastics — finding that combined stressors often cause more harm than individual stresses acting alone.
Microplastics promote the invasiveness of invasive alien species under fluctuating water regime
Researchers found that microplastic pollution in soil can enhance the invasiveness of alien plant species, particularly under fluctuating water conditions that simulate extreme rainfall events. The microplastics altered soil properties in ways that gave invasive plants a competitive advantage over native species. The study highlights a previously overlooked interaction between two major environmental threats: microplastic contamination and biological invasions.
Interactive impacts of heat stress and microplastics contamination on the growth and biochemical response of wheat (Triticum aestivum) and maize (Zea mays) plants
Researchers investigated how heat stress combined with polyethylene microplastic contamination in soil affects wheat and maize growth. They found that the combination significantly reduced plant height, root length, leaf area, and chlorophyll content more than either stressor alone. The findings highlight that microplastic pollution in agricultural soils could worsen the damage already caused by rising temperatures to food crops.
The more microplastic types pollute the soil, the stronger the growth suppression of invasive alien and native plants
Researchers grew 16 plant species in soil contaminated with varying numbers of microplastic types and found that plant growth declined more as the diversity of microplastics increased. Invasive species were particularly affected, losing their typical growth advantage over native plants when exposed to multiple microplastic types. The study suggests that real-world soil contamination, which typically involves a mix of different plastics, may suppress plant growth more than single-plastic experiments have shown.
Root traits and rhizosphere responses as emerging bioindicators of microplastic pollution in agricultural soils: A review
This review examines how microplastic pollution in agricultural soils disrupts root growth, nutrient uptake, and the beneficial interactions between plant roots and soil microbes. Researchers found that microplastics can alter root exudation patterns, change soil structure, and shift microbial communities around roots in ways that may impair crop productivity. The study proposes that root traits and rhizosphere responses could serve as early warning indicators of microplastic contamination in farmland.
Oxidative Damage in Roots of Rice (Oryza sativa L.) Seedlings Exposed to Microplastics or Combined with Cadmium
Rice seedlings exposed to polystyrene microplastics and cadmium showed combined toxic effects on root growth, fresh and dry weight, and antioxidant enzyme activities, with combined exposure producing greater oxidative damage than either pollutant alone. The study highlights synergistic phytotoxicity in a staple crop relevant to food security in microplastic-contaminated paddy soils.
Microplastic particles increase arsenic toxicity to rice seedlings
Researchers studied how polystyrene and polytetrafluoroethylene microplastics interact with arsenic to affect rice seedling growth. They found that microplastics alone reduced plant biomass and inhibited photosynthesis, while the combination with arsenic at higher concentrations amplified the toxic effects on root activity and cell membranes. The study reveals that microplastic contamination in agricultural settings may worsen the impact of other pollutants on food crops.
The effect of microplastic pollution on rice growth, paddy soil properties, and greenhouse gas emissions: A global meta-analysis
This global meta-analysis of 40 studies found that microplastics reduce rice biomass by inducing oxidative stress and inhibiting photosynthesis, while depleting soil nitrogen, phosphorus, and organic carbon. Microplastics also stimulate nitrous oxide emissions from paddy soils, posing a dual threat to food security and climate through impaired rice production and increased greenhouse gas output.
Ecological and physiological risks of micro- and nanoplastics in rice agroecosystems: Challenges and engineering-based mitigation approaches
Researchers reviewed how micro- and nanoplastics harm rice — a staple crop feeding billions — by disrupting root growth, reducing photosynthesis, altering soil microbes, and making heavy metals more available to plants. The review proposes that ecological engineering strategies like microbial bioremediation and organic soil amendments could help protect agricultural land from plastic contamination.
Cascading effects from soil to maize functional traits explain maize response to microplastics disturbance in multi-nutrient soil environment
Researchers found that microplastics in agricultural soil can dry out the soil and disrupt nutrient availability for maize plants, but the crop partially compensates by growing longer, more efficient roots to forage for nutrients. This adaptive response — more pronounced in nutrient-rich soils — means microplastic impacts on crop yields depend heavily on soil conditions, complicating efforts to predict food security risks from plastic pollution.
Co-exposure to microplastics and soil pollutants significantly exacerbates toxicity to crops: Insights from a global meta and machine-learning analysis
A large-scale analysis of 68 studies found that when microplastics combine with other soil pollutants, the harm to crops is significantly worse than from the other pollutants alone. Microplastics intensified damage to plant growth, increased oxidative stress, and reduced photosynthesis efficiency. Interestingly, microplastics did reduce the amount of other pollutants that accumulated in the crops, but the overall toxic effects on plant health were still greater.
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 combined microplastics and heavy metals pollution on terrestrial plants and rhizosphere environment: A review
This review summarizes how microplastics and heavy metals interact in soil to affect plant growth and the surrounding ecosystem. When present together, these pollutants cause significantly more harm than either alone, reducing plant weight by up to 87.5% and altering how heavy metals accumulate in crops -- raising concerns about food safety and human exposure through contaminated agricultural products.
Influence of soil microplastic contamination and cadmium toxicity on the growth, physiology, and root growth traits of Triticum aestivum L.
Researchers grew wheat plants in soil contaminated with polyethylene microplastics, the toxic heavy metal cadmium, or both, finding that combined exposure caused the worst damage — shrinking root area, reducing gas exchange in leaves, and lowering key growth indicators. These findings raise concerns about crop yields in farmland where plastic pollution and heavy metal contamination overlap, which is increasingly common.
