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.
Microplastics in terrestrial ecosystem: Exploring the menace to the soil-plant-microbe interactions
This review summarizes existing research on how microplastics affect the complex relationships between soil, plants, and soil microbes. Microplastics alter soil structure, change the makeup of microbial communities, and disrupt beneficial partnerships between plants and helpful fungi and bacteria. These disruptions can reduce plant growth and nutrient cycling, which could ultimately affect crop yields and the quality of food produced on microplastic-contaminated farmland.
A critical review of co-pollution of microplastics and heavy metals in agricultural soil environments
This review examines how microplastics and heavy metals frequently occur together in agricultural soil, where they interact in ways that can increase the toxicity of both. These co-contaminants can harm soil organisms, reduce crop productivity, and potentially enter the human food chain, making their combined presence in farmland a growing concern for food safety and health.

Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
This review examines how microplastics affect soil microbial communities and plant systems in agricultural settings, documenting impacts on soil health, microbial diversity, and crop physiology. As microplastics accumulate in farmland soils through irrigation, sludge application, and plastic mulches, their effects on the soil ecosystem that underpins food production are a growing concern.
Microplastics in Agricultural Soils: An Emerging Threat to Soil Health, Microbial Ecology, Crop Productivity, and Food Safety
This review examines how microplastics accumulate in agricultural soils from sources like plastic mulch, sewage sludge, and atmospheric deposition. Researchers found that these particles can disrupt soil microbial communities, harm plant health, and potentially enter the human food chain. The study highlights the urgent need for mitigation strategies to address this growing but often overlooked form of pollution in farmland.
Micro and nano-plastics on environmental health: a review on future thrust in agro-ecotoxicology management
This review examines the growing body of evidence on how microplastics and nanoplastics affect plant health, soil microbial communities, and agricultural productivity. The study highlights that plastic accumulation in agricultural soils can alter crop growth and yield while disrupting soil ecosystem dynamics, and calls for greater attention to agro-ecotoxicology management to address these emerging threats to food production.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
Invisible threats in soil: Microplastic pollutionand its effects on soil health and plant growth
This review summarizes current knowledge about microplastic contamination in agricultural soil, covering where the plastics come from, how they move through soil, and what they do to soil health and plant growth. Microplastics can alter soil structure, disrupt microbial communities, and interfere with nutrient cycles that plants need to grow. The findings raise concerns that widespread microplastic pollution in farmland could quietly reduce crop quality and productivity, ultimately affecting the food supply.
The effect of soil microplastics on Oryza sativa L. root growth traits under alien plant invasion
Researchers studied how microplastics in soil interact with an invasive weed species to affect rice root growth. Both stressors individually harmed rice roots, but their combination produced complex interactive effects that altered root architecture and nutrient uptake. This suggests that microplastic pollution in farmland may compound the damage caused by invasive plants, creating compounding threats to crop productivity.
[Adverse Effects and Underlying Mechanisms of Soil Microplastics on Crops and Its Preventive Strategies].
This review summarizes the pollution status of microplastics in agricultural soils and their adverse effects on crops, including mechanical damage, oxidative stress, and genotoxicity leading to disrupted plant growth and metabolism. Researchers also examined how hazardous substances released from microplastics and contaminants adsorbed onto their surfaces contribute to soil ecosystem harm. The study identifies source control and biodegradation as the most promising strategies for reducing microplastic risks to crop production.
Toxicological complexity of microplastics in terrestrial ecosystems
This review summarizes how microplastics interact with other pollutants like heavy metals and pesticides in soil, creating combined toxic effects that threaten ecosystems and agriculture. The paper highlights that microplastics can change soil structure and disrupt the communities of microorganisms that keep soil healthy, with ripple effects on crop yields and food security.
Coupled effects of microplastics and heavy metals on plants: Uptake, bioaccumulation, and environmental health perspectives
This review examines how microplastics and heavy metals work together to harm plants when both are present in soil. Microplastics can absorb heavy metals like lead, cadmium, and arsenic, and when plants take up these contaminated particles, the combined toxic effect is worse than either pollutant alone. This is concerning for human health because crops grown in contaminated soil could carry both microplastics and concentrated heavy metals into the food supply.
Silent Alienation of Soils through Microplastic in the Anthropocene – A Constraint for Soil Productivity?
This review examines how microplastics accumulate in soils and alter their physical properties and biological communities over time. Microplastics resist biodegradation and can reduce soil porosity, alter water retention, and harm soil organisms. The authors argue that ongoing plastic accumulation in farmland poses a long-term threat to soil productivity and global food security.

Microplastics in agroecosystems: A review of effects on soil biota and key soil functions
This review examines how microplastic and nanoplastic contamination in agricultural soils affects soil organisms and ecological functions. Researchers found that plastics enter farmland through multiple pathways including plastic mulch, sewage sludge, and irrigation water, and once present they alter soil properties and exhibit toxic behavior toward soil biota. The study identifies significant knowledge gaps about the long-term impacts of microplastic accumulation on agricultural productivity and food safety.

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.
