ClearCombined 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.
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.
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.
Co-existence of polyethylene microplastics and tetracycline on soil microbial community and ARGs
This study examined how polyethylene microplastics and the antibiotic tetracycline interact in soil. When present together, they altered soil microbial communities and increased the abundance of antibiotic resistance genes more than either contaminant alone. The findings raise concerns that microplastics in agricultural soil may worsen the spread of antibiotic resistance, a growing public health challenge.
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.
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.
Microplastics combined with tetracycline in soils facilitate the formation of antibiotic resistance in the Enchytraeus crypticus microbiome
Soil invertebrates (Enchytraeus crypticus) were exposed to microplastics and tetracycline alone and in combination; combined exposure promoted greater shifts in gut microbiome composition and higher levels of antibiotic resistance genes than either stressor alone, suggesting microplastics exacerbate antibiotic resistance spread in soil.
The combined effect of microplastics and tetracycline on soil microbial communities and ARGs
Researchers studied how simultaneous exposure to microplastics and tetracycline affects soil microbial communities, finding that the combination disrupted microbial diversity, altered functional gene expression, and promoted horizontal transfer of antibiotic resistance genes beyond the effects of either pollutant alone.
Metagenomics reveals combined effects of microplastics and antibiotics on microbial community structure and function in coastal sediments
A metagenomic study of coastal sediments exposed to combined microplastic and antibiotic pollution found that co-exposure altered microbial community composition and significantly elevated the abundance and diversity of antibiotic resistance genes compared to either pollutant alone.
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.
Response of wheat (Triticum aestivum L. cv.) to the coexistence of micro-/nanoplastics and phthalate esters alters its growth environment
Researchers studied how wheat responds to co-existing stressors of microplastics and another soil contaminant, finding that combined exposure altered plant growth, physiological parameters, and grain quality compared to single-stressor exposures. The results highlight the importance of testing contaminant mixtures in agricultural soils.
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.
Stress response to oxytetracycline and microplastic-polyethylene in wheat (Triticum aestivum L.) during seed germination and seedling growth stages
Researchers investigated the combined effects of the antibiotic oxytetracycline and polyethylene microplastics on wheat seed germination and seedling growth. The study found that while oxytetracycline caused direct toxicity to plant growth, the presence of microplastics modified the antibiotic's effects in complex ways, reprogramming metabolic profiles in wheat leaves differently than either contaminant 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.
Impact of Abiotic Stressors on Soil Microbial Communities: A Focus on Antibiotics and Their Interactions with Emerging Pollutants
This review examines how environmental stressors, especially antibiotics, affect the microbial communities that keep soil healthy and fertile. It also covers how antibiotics interact with other emerging pollutants like microplastics and heavy metals in soil. When microplastics carry antibiotics into soil, the combination can promote the spread of antibiotic-resistant bacteria, which is a growing concern for human health.
Coupling polyethylene microplastics with other pollutants: Exploring their combined effects on plant health and technologies for mitigating toxicity
This review summarizes how polyethylene microplastics interact with other common soil pollutants like heavy metals and antibiotics in agricultural fields. Microplastics can absorb these pollutants and carry them into plants, making the combined exposure more harmful than either pollutant alone. The findings raise concerns about the safety of crops grown in microplastic-contaminated soil.
Integrated Effects of Polyamide Microplastics and Three Abundant Antimicrobials and Reclaimed Water On The Growth of Lettuce and Soil Bacterial Communities
Researchers investigated the combined effects of polyamide microplastics and three common antimicrobials -- sulfamethoxazole, ciprofloxacin, and triclosan -- alongside reclaimed water irrigation on lettuce growth and soil bacterial community composition. The study examined how simultaneous exposure to microplastics and pharmaceutical contaminants alters soil microbial ecology in agricultural settings.
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.
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.
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.
