ClearImpact of microplastics aerial deposition on rhizosphere soil ecology: the case study of tomato (Solanum lycopersicum) exposed to polyethylene
Researchers investigated the impact of aerial polyethylene microsphere deposition on tomato plants at concentrations of 10, 100, and 1000 mg/L, finding that while shoot biomass was unaffected, exposure significantly altered root metabolite profiles (increasing amino acids, decreasing fatty acids and organic acids) and shifted rhizosphere bacterial and fungal community composition.
The short-term effect of microplastics in lettuce involves size- and dose-dependent coordinate shaping of root metabolome, exudation profile and rhizomicrobiome
Researchers exposed lettuce plants to polyethylene plastic particles of four different sizes and concentrations, finding that the plastics altered root chemistry, changed what the roots released into the soil, and shifted the bacteria living around them. The effects depended strongly on particle size, with smaller particles causing different metabolic changes than larger ones. This study shows that microplastics in farm soil can change the biology of food crops from the roots up, potentially affecting both crop health and nutritional quality.

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.
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.

The study highlights that plastic pollution in soil threatens not only plant health but also the broader rhizosphere ecosystem that supports agriculture.

This review synthesizes current knowledge on how microplastics affect soil health and plant growth in agricultural systems, with insights from advanced omics technologies. Researchers found that microplastics degrade soil structure, disrupt nutrient cycles, alter microbial communities, and can be taken up by plant roots, triggering oxidative stress and impaired growth. The study highlights how transcriptomics, metabolomics, and proteomics are revealing the molecular-level stress responses plants mount against microplastic exposure.

A new quantitative insight: Interaction of polyethylene microplastics with soil - microbiome - crop
Researchers developed a new method to track and measure how polyethylene microplastics move through soil and into crops, and for the first time demonstrated that micron-sized particles can accumulate in plant tissues, with the highest concentrations found in roots. Weathered microplastics significantly reduced soil nutrients and inhibited plant growth in maize, while fresh microplastics had different effects on soil chemistry. The findings suggest that aging microplastics in agricultural soil may pose a greater risk to crop productivity than previously understood.

Researchers used a root-box system to examine how nanoplastics and the plasticizer DEHP interact in the rhizosphere of tomato plants, finding that DEHP dominated the plastic pollution risk to plants and that nanoplastic co-exposure did not mitigate DEHP toxicity to soil microorganisms but increased it for food safety.
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.
