ClearInfluence of microplastic addition on glyphosate decay and soil microbial activities in Chinese loess soil
Adding polyethylene microplastics to soil influenced the degradation of the herbicide glyphosate and altered microbial activity, with effects depending on the concentration of both microplastics and glyphosate. The findings suggest that microplastic contamination in agricultural soils could affect how long pesticides persist and how soil microbes function.
Impact of co-occurrence of microplastics and lindane on lindane biodegradation and soil carbon cycling in flooding environments
The co-occurrence of microplastics and the pesticide lindane in soil affected the degradation rate of lindane by soil microorganisms, with microplastics either accelerating or inhibiting pesticide breakdown depending on conditions. This shows that microplastics can alter the environmental fate of co-present pesticides, complicating risk assessments for contaminated soils.

Researchers examined how the fungicide prothioconazole affects the degradation of microplastics derived from polyethylene mulch film and biodegradable PBAT film in agricultural soil, finding that the pesticide inhibited microbial communities responsible for plastic breakdown and slowed degradation rates. The study highlights an underappreciated interaction between agricultural chemical use and plastic persistence in soil.
Adsorption of azoxystrobin and pyraclostrobin onto degradable and non-degradable microplastics: Performance and mechanism
Researchers studied how two common fungicide pesticides attach to both biodegradable and conventional microplastics in soil environments. They found that non-degradable microplastics absorbed more pesticide and released it more slowly than biodegradable alternatives. The study suggests that microplastics in agricultural soil may act as reservoirs for pesticides, potentially prolonging their environmental presence and ecological impact.
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.
Insight into the effect of microplastics on the adsorption and degradation behavior of thiamethoxam in agricultural soils
Researchers found that microplastics in agricultural soil alter both the adsorption and degradation behavior of the pesticide thiamethoxam, with different plastic types showing varying effects on how the pesticide binds to soil and breaks down over time.
Different effects of polyethylene microplastics on bioaccumulation of three fungicides in maize (Zea mays L.)
Polyethylene microplastics in agricultural soil altered the sorption and dissipation of three fungicides and their accumulation in maize plants, with effects differing by fungicide type and plastic particle concentration.
Interaction effects and mechanisms of microorganisms and microplastics in soil environment
This review examines how microplastics and soil microorganisms interact: microplastics disrupt soil structure, reduce water retention, and impede plant root growth, while certain bacteria and fungi can colonize and partially degrade plastic particles through a multi-step process involving colonization, fragmentation, assimilation, and mineralization. Different polymer types (PE, PP, PS, PVC, PET) attract different microbial communities, and factors like temperature, moisture, and plastic additives affect degradation rates. Understanding these interactions is key to assessing long-term soil health impacts and developing microbial strategies to reduce plastic accumulation in agricultural soils.
Effect of propiconazole on plastic film microplastic degradation: Focusing on the change in microplastic morphology and heavy metal distribution
Researchers investigated how the fungicide propiconazole affects the degradation of PBAT and polyethylene plastic films in agricultural soils, examining changes in surface morphology and heavy metal adsorption and release characteristics at varying concentrations and soil pH values. The study found that propiconazole influenced microplastic degradation patterns and associated heavy metal distribution, with implications for contaminated agricultural soils.
Effects of co-loading of polyethylene microplastics and ciprofloxacin on the antibiotic degradation efficiency and microbial community structure in soil
Researchers studied how polyethylene microplastics and the antibiotic ciprofloxacin together affect soil microbial communities and antibiotic degradation. The study found that co-loading of microplastics with antibiotics altered microbial community structure and affected the rate of antibiotic degradation in soil, suggesting microplastic contamination may influence how soils process pharmaceutical pollutants.

[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
Adaptation of the metolachlor-degrading fungus Trichoderma harzianum to the simultaneous presence of low-density polyethylene (LDPE) microplastics
When LDPE microplastics and the herbicide metolachlor were both present in soil, the soil fungus Trichoderma harzianum showed altered membrane lipid composition but continued to break down the herbicide at normal rates. This suggests that while microplastics can stress soil microorganisms, they may not always impair the soil's ability to degrade agricultural chemicals — an important finding for understanding how plastic pollution affects farmland ecosystem function.
Microbial remediation of microplastic-contaminated soil, focusing on mechanisms, benefits, and research gaps
This systematic review examines microbial bioremediation of microplastic-contaminated soils, covering the sources and distribution of soil microplastics, their physicochemical interactions with soil microbiomes, and the mechanisms by which soil-dwelling bacteria and fungi degrade plastic polymers.
Influence of microplastic contamination on the dissipation of endocrine disrupting chemicals in soil environment
Researchers studied how the presence of microplastics in soil affects the breakdown of endocrine disrupting chemicals, finding that microplastic contamination can alter the dissipation rates of these harmful compounds. The study tested different types and concentrations of microplastics in alluvial soil environments. Evidence indicates that microplastics may slow the natural degradation of endocrine disruptors, potentially prolonging their presence and ecological impact in contaminated soils.
The Spatiotemporal Successions of Bacterial and Fungal Plastisphere Communities and Their Effects on Microplastic Degradation in Soil Ecosystems
Researchers tracked how bacterial and fungal communities colonize microplastic surfaces in soil over time, finding that the surrounding soil type had the strongest influence on which microbes grew on the plastics. The microbial communities on microplastics were less diverse and less stable than those in the surrounding soil, but they attracted microbes with a higher capacity to break down organic carbon. The study suggests that microplastic surfaces become hotspots for carbon metabolism in soil ecosystems.

Researchers tested whether bacterial and fungal isolates from landfill leachate could degrade polyethylene and polypropylene microplastics in artificially polluted agricultural soil, finding that the microbial isolates showed measurable degradation activity against both polymer types.
Interactions of microplastics with pesticides and anthelminthics mediate undesirable effects on microbial nitrogen cycling in agricultural soils
Researchers investigated how three microplastic types (LDPE, PBAT, and starch-based) interact with the fungicide pyraclostrobin and the anthelmintic fenbendazole in agricultural soils, measuring effects on soil microbiota. Combined exposures often produced non-additive or antagonistic effects on microbial communities, complicating risk assessments of MPs in agricultural settings.
Microplastic accumulation in soils: Unlocking the mechanism and biodegradation pathway
Researchers reviewed how microplastics accumulate in soil and break down biologically, finding that certain microorganisms can form biofilms on plastic surfaces and use enzymes to slowly degrade the polymers — though conditions like pH, temperature, and moisture must be optimized and new plastic-degrading microbes need to be identified before this approach can be widely applied.
Adsorption–desorption and leaching behavior of benzovindiflupyr in different soil types
This study examined how the fungicide benzovindiflupyr behaves in different soil types, finding that microplastics in soil can change how the pesticide is absorbed and moves through the ground. The type and size of microplastics influenced whether the fungicide stayed in place or leached toward groundwater. This is relevant because when microplastics and agricultural chemicals coexist in farmland, they can interact in ways that may increase groundwater contamination and human exposure.
