ClearCombined effects of mulch film-derived microplastics and pesticides on soil microbial communities and element cycling
Researchers studied how microplastics from agricultural plastic mulch film interact with commonly used pesticides in cotton field soil. When present together, the pesticides had a stronger impact on soil bacteria than the microplastics alone, and the combination disrupted important nutrient cycling processes for carbon, nitrogen, and phosphorus. This matters because farmland contaminated with both microplastics and pesticides may experience compounding damage to soil health, ultimately affecting food production.
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. Both conventional polyethylene and biodegradable polylactic acid microplastics interacted with the antibiotic to change bacterial diversity and soil chemistry. The results show that microplastics and antibiotics in agricultural soil can have compounding effects on soil health, potentially affecting the crops grown in it.
Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
Interactions of microplastics with pesticides and anthelminthics mediate undesirable effects on microbial nitrogen cycling in agricultural soils
This study examined how microplastics (LDPE, PBAT, and starch-based) interact with pesticides and veterinary medicines to affect soil microbiota. The co-exposure of MPs with these agricultural chemicals produced undesirable effects on microbial communities beyond those of each contaminant alone.
Impacts of the coexistence of polystyrene microplastics and pesticide imidacloprid on soil nitrogen transformations and microbial communities
Researchers investigated the combined effects of polystyrene microplastics and the pesticide imidacloprid on soil nitrogen cycling and microbial communities over 28 days. They found that both pollutants individually and together significantly altered nitrogen transformation processes and shifted microbial community composition. The study suggests that the co-presence of microplastics and pesticides in agricultural soils can create compounding disruptions to essential nutrient cycling.
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.
Effects of co-exposure of antibiotic and microplastic on the rhizosphere microenvironment of lettuce seedlings
Researchers examined how the combination of antibiotics and polyethylene microplastics in agricultural soil affects lettuce seedling growth and the microbial community around plant roots. They found that combined exposure altered soil bacterial diversity, changed the chemical profile of root-zone metabolites, and affected nutrient cycling differently than either contaminant alone. The study highlights the compounding environmental risks when antibiotics from animal manure and microplastics from plastic films co-exist in farmland soils.
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.
Polyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality
Researchers studied how polyethylene microplastics at different concentrations affect soil microbial communities and overall ecosystem function in a maize growing system. They found that higher concentrations of microplastics shifted microbial community composition, reduced beneficial bacteria involved in nutrient cycling, and impaired multiple soil ecosystem functions simultaneously. The study suggests that microplastic contamination in agricultural soils can undermine the biological processes that support healthy crop growth.
Polyethylene microplastics distinctly affect soil microbial community and carbon and nitrogen cycling during plant litter decomposition
Researchers measured how polyethylene microplastics affect soil microbial communities and carbon cycling in agricultural soils, finding that microplastic addition shifted microbial diversity and suppressed key carbon mineralization processes. The results suggest microplastic accumulation in farmland could impair soil carbon storage.
Effects of hexabromocyclododecane and polyethylene microplastics on soil bacterial communities
Researchers examined how the flame retardant hexabromocyclododecane and polyethylene microplastics, both separately and combined, affect bacterial communities in agricultural soil over four months. They found that microplastics and the combined exposure significantly altered bacterial diversity, while the flame retardant alone had less impact at low concentrations. The study suggests that the interaction between microplastics and chemical pollutants in soil can reshape microbial communities in ways that may affect soil function.
Influence 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.
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.

Researchers investigated how conventional and biodegradable microplastics alter soil nutrient balances and the resulting effects on microbial metabolism, community diversity, and species interactions. The study found that microplastic-induced nutrient imbalances significantly influenced soil microbial processes, with different types of microplastics producing distinct effects on carbon and nitrogen cycling.
Microplastics Trigger Soil Dissolved Organic Carbon and Nutrient Turnover by Strengthening Microbial Network Connectivity and Cross-Trophic Interactions
This study found that polyethylene and PVC microplastics in agricultural soil significantly altered the microbial communities responsible for breaking down organic carbon and recycling nutrients. The microplastics strengthened connections between bacteria, fungi, and other microorganisms in ways that accelerated carbon and nutrient turnover. These changes to fundamental soil processes could affect crop nutrition and long-term soil health on farms contaminated with microplastics.
Dissipation of penthiopyrad in polyethylene microplastics coexisting soils: Roles of soil properties and microbial communities
Researchers studied how polyethylene microplastics affect the breakdown of the fungicide penthiopyrad in soil and found that the plastics modified dissipation rates through adsorption and desorption but did not significantly alter the fungicide's ultimate persistence. Specific bacterial and fungal genera, including Sphingomonas and Trichocladium, played key roles in degrading the fungicide. The study highlights that soil microorganisms could serve as natural remediation agents for co-contamination by microplastics and pesticides.
