Insight into combined pollution of antibiotics and microplastics in aquatic and soil environment: Environmental behavior, interaction mechanism and associated impact of resistant genes
This review examines the combined pollution created when microplastics absorb antibiotics in water and soil environments. Researchers found that microplastics can concentrate antibiotics on their surfaces, and this combination promotes the spread of antibiotic-resistant genes in microbial communities. The study highlights that the interaction between these two emerging pollutants may pose greater environmental and health risks than either one alone.
Effect of polyethylene microplastics on antibiotic resistance genes: A comparison based on different soil types and plant types
This study compared how polyethylene microplastics affect antibiotic resistance genes across different soil types and found that contaminated soils and the presence of certain plants influenced which resistance genes proliferated. The results suggest that microplastics in agricultural soil can help spread antibiotic resistance, which is a serious concern for human health because resistant bacteria can enter the food supply through crops.
Combined effects of oxytetracycline and microplastic on wheat seedling growth and associated rhizosphere bacterial communities and soil metabolite profiles
Researchers examined how the antibiotic oxytetracycline combined with polyethylene microplastics affects wheat seedling growth and soil microbial communities. They found that high concentrations of the antibiotic combined with microplastics significantly reduced seedling growth and altered the bacterial communities around the roots. The study reveals that the co-presence of antibiotics and microplastics in agricultural soils may create compounding negative effects on crop health.
Varying characteristics and driving mechanisms of antibiotic resistance genes in farmland soil amended with high-density polyethylene microplastics
A 60-day soil experiment found that high-density polyethylene microplastics containing phthalate additives significantly enhanced antibiotic resistance gene abundance in farmland soil compared to plastics without phthalates, identifying phthalate release as a key driver of microplastic-associated ARG enrichment.
Characteristics of tetracycline antibiotic resistance gene enrichment and migration in soil–plant system
This review examines how tetracycline antibiotic resistance genes spread through soil and into plants, with microplastics identified as one of the factors that accelerate this process. Resistance genes can transfer from soil bacteria into plant tissues through root absorption, ultimately accumulating in edible parts like leaves and fruits. This means microplastic-contaminated agricultural soil could help spread antibiotic resistance to humans through the food they eat.
Assessment of the Effects of Biodegradable and NonbiodegradableMicroplastics Combined with Pesticides on the Soil Microbiota
This study investigated how biodegradable (PLA) and non-biodegradable (PET) microplastics interact with glyphosate and imidacloprid pesticides in soil, finding that PLA increased microbial diversity while both microplastic types amplified the spread of antibiotic resistance genes when combined with pesticides.
The Individual and Combined Effects of Microplastics and Antibiotics on Soil Microbial Metabolic Limitation and Carbon Use Efficiency
Researchers tested how polyethylene microplastics, biodegradable polylactic acid microplastics, and the antibiotic oxytetracycline individually and together affect soil microbial metabolism. When microplastics and antibiotics were combined, they shifted the nutrient limitation of soil microbes from nitrogen to phosphorus and reduced the efficiency with which microbes use carbon. The study suggests that the combined presence of microplastics and antibiotics in agricultural soils could disrupt fundamental nutrient cycling processes.
Microplastics inhibit oxytetracycline degradation in soils: Insights into biofilm-enhanced adsorption and microbial community shifts
Researchers examined how polyethylene and polylactic acid microplastics affect oxytetracycline degradation in organic fertilizer-amended paddy soil, finding that both plastic types significantly inhibited antibiotic degradation by lowering degradation rates 11.1-20.2%. Biofilm formation on microplastic surfaces enhanced oxytetracycline adsorption and shifted microbial community composition, reducing the abundance of antibiotic-degrading microorganisms.

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.
Assessment of the Effects of Biodegradable and Nonbiodegradable Microplastics Combined with Pesticides on the Soil Microbiota
This study compared how biodegradable PLA and conventional PET microplastics, combined with common pesticides, affect soil microbial communities. Researchers found that PLA microplastics significantly increased microbial diversity but also enriched potentially harmful bacteria and elevated antibiotic resistance gene abundance more than PET, suggesting biodegradable plastics may pose underappreciated ecological risks in agricultural soils.
Combined contamination of microplastic and antibiotic alters the composition of microbial community and metabolism in wheat and maize rhizosphere soil
A study found that when soil is contaminated with both microplastics and antibiotics together, the damage to wheat and maize seedlings is worse than from either contaminant alone, with increased root oxidative stress and disrupted soil bacterial communities. This combined contamination, common in agricultural soils treated with plastic mulch and livestock manure, could affect crop health and food quality.
Microplastic-mediated interactions with antibiotics and antibiotic resistance genes in sludge: combined effects and environmental implications
This review summarized the co-occurrence and interactions of microplastics, antibiotics, and antibiotic resistance genes (ARGs) in sludge environments, finding that their interactions are primarily controlled by hydrogen bonding, hydrophobic forces, and electrostatic interactions, with biofilm formation playing a critical role. The combined ecological risks of these three pollutants in soil were shown to negatively affect soil microorganisms, plants, animals, and biogeochemical element cycling.
Sources, interactions, influencing factors and ecological risks of microplastics and antibiotic resistance genes in soil: A review
Microplastics in soil serve as hotspots for antibiotic resistance genes, with the plastisphere — the microbial community colonizing plastic surfaces — facilitating horizontal gene transfer of resistance markers. Key factors driving this interaction include microplastic properties, soil chemistry, and agricultural practices, though research in soil environments is still at an early stage compared to aquatic systems.
Unraveling the combined impacts of pristine and aged polyethylene microplastics and the ciprofloxacin antibiotic on sediment microbial communities and ecological functions
Researchers examined how polyethylene microplastics — both fresh and environmentally weathered — interact with the antibiotic ciprofloxacin to affect the microbial communities living in aquatic sediments. They found that microplastics, especially in combination with the antibiotic, disrupted microbial community structure and simplified the ecological networks that microbes rely on for stable functioning. This is concerning because healthy sediment microbe communities underpin nutrient cycling and ecosystem health, and their disruption by combined plastic-antibiotic pollution could have cascading effects.
Microplastic diversity increases the abundance of antibiotic resistance genes in soil
When different types of microplastics accumulate together in soil, they increase the spread of antibiotic resistance genes in bacteria. The more diverse the mix of microplastic shapes, colors, and types, the greater the increase in these resistance genes. This is concerning for human health because antibiotic-resistant bacteria in soil can potentially transfer to people through food and water.
Changes in tetracycline partitioning and bacteria/phage-comediated ARGs in microplastic-contaminated greenhouse soil facilitated by sophorolipid
This study investigated how the soil surfactant sophorolipid influences the fate of tetracycline and antibiotic resistance genes (ARGs) in greenhouse soil that is also contaminated with microplastics. The findings highlight that microplastics can complicate antibiotic dissipation by affecting how bacteria and bacteriophages interact with both antibiotics and resistance genes.
