ClearMicrobial metabolism in wormcast affected the perturbation on soil organic matter by microplastics under decabromodiphenyl ethane stress
Researchers examined how microplastics combined with a brominated flame retardant affect soil health through earthworm activity. They found that microplastics altered the microbial communities in earthworm castings, which in turn changed how soil organic matter was processed. The study suggests that co-pollution from microplastics and flame retardants can disrupt important soil ecosystem functions that depend on earthworm-microbe interactions.
Microbiomes of coastal sediments and plastispheres shaped by microplastics and decabrominated diphenyl ether
This two-year study examined how microplastics and a common flame retardant pollutant interact in coastal sediments and found that microplastics accelerated the breakdown of the flame retardant while creating specialized communities of bacteria on their surfaces. The findings show that microplastics in the environment do not act alone but change how other pollutants behave and spread, potentially affecting the broader ecosystem and food web.
The impact of microplastic and sulfanilamide co-exposure on soil microbiota
This study investigated what happens when microplastics and the antibiotic sulfanilamide are present together in soil, finding that the combination significantly altered soil microbial communities compared to either pollutant alone.

Effect of flumetsulam alone and coexistence with polyethylene microplastics on soil microbial carbon and nitrogen cycles: Elucidation of bacterial community structure, functional gene expression, and enzyme activity
Researchers tested how the herbicide flumetsulam interacts with polyethylene microplastics in soil and found that both individually and together they reduced bacteria and fungi populations. When microplastics were present alongside the herbicide, the soil bacterial community shifted more dramatically, though carbon and nitrogen cycling remained largely unchanged. The study suggests that the combined presence of herbicides and microplastics in agricultural soil creates distinct effects on microbial life compared to either contaminant alone.
[Effect of Microplastics and Phenanthrene on Soil Chemical Properties, Enzymatic Activities, and Microbial Communities].
A 300-day experiment tested how polyethylene and polypropylene microplastics, alone and combined with the PAH pollutant phenanthrene, affected soil chemistry, enzyme activity, and microbial communities. The results showed that microplastics and phenanthrene interacted to reshape soil microbial composition and function in ways that neither contaminant produced alone, suggesting that co-contamination by microplastics and organic pollutants poses compounded risks to soil ecosystem health.
Independent and combined effects of microplastics pollution and drought on soil bacterial community
Researchers studied how polyethylene and polylactic acid microplastics, combined with drought conditions, affect soil bacteria. Very small (20 micrometer) biodegradable PLA microplastics significantly reduced bacterial diversity by over 17%, while conventional polyethylene had less impact. The results suggest that the combined stress of microplastic pollution and drought could meaningfully alter soil microbial communities that are essential for healthy ecosystems and agriculture.

Responses of microbial communities to the addition of different types of microplastics in agricultural soils
Researchers conducted a 90-day soil incubation study to examine how four types of microplastics — polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate — affect agricultural soil properties and microbial communities. They found that all four types significantly altered soil enzyme activities, nutrient content, and the diversity of microbial populations. The study indicates that microplastic contamination in farmland can disrupt soil health in ways that may affect agricultural productivity.
Accumulation of microplastics and Tcep pollutants in agricultural soil: Exploring the links between metabolites and gut microbiota in earthworm homeostasis
Researchers investigated the co-occurrence of polyethylene microplastics and the flame retardant TCEP in agricultural soils and their combined effects on earthworm health. The study found that co-exposure disrupted earthworm gut microbiota and metabolic homeostasis, suggesting that the interaction between microplastics and chemical additives in agricultural soil may pose greater ecological risks than either contaminant alone.
Time-dependent effects of microplastics on soil bacteriome
Researchers studied how six common types of microplastics affect soil bacteria over time at realistic contamination levels. The effects were slow to appear due to the chemical stability of plastics, but over time, microplastics altered bacterial community structure and soil functions in ways that differed by plastic type. This matters because changes to soil bacteria can affect nutrient cycling and crop health, with potential downstream effects on food quality.
The effects of single and combined pollution of PE microplastics and antibiotics in soil on wheat (Triticum aestivum L.) seedlings
This study examined the combined effects of polyethylene microplastics and antibiotic exposure on soil organisms, finding that mixture exposure altered soil microbial community structure and promoted antibiotic resistance gene abundance more than either stressor alone. Co-exposure to microplastics and antibiotics poses compounded risks for soil microbiomes.
Microplastics in heavy metal-contaminated soil drives bacterial community and metabolic changes
Researchers found that adding common microplastics to soil already contaminated with heavy metals significantly changed the bacterial communities and their metabolic processes. The microplastics increased competition among bacteria and shifted how they process energy, while Proteobacteria became more abundant as a stress response. This matters because when microplastics and heavy metals combine in agricultural soil, they may disrupt the microbial ecosystems that keep soil healthy for growing food.

Microplastics change soil properties, heavy metal availability and bacterial community in a Pb-Zn-contaminated soil
This study found that adding six different types of microplastics to soil contaminated with lead and zinc changed the soil's chemistry, increased the availability of those toxic metals, and shifted the bacterial communities living in the soil. Higher doses of microplastics caused greater disruption, reducing microbial diversity and altering nutrient cycling. The findings suggest that microplastics in contaminated soil could make heavy metals more likely to enter plants and the food chain.
