ClearAntibiotic sorption onto MPs in terrestrial environment: a critical review of the transport, bioaccumulation, ecotoxicological effects and prospects
This review examines how microplastics in soil absorb and transport antibiotics, creating complex pollutants that can spread antibiotic resistance genes through the environment. When antibiotic-carrying microplastics are taken up by plants or soil organisms, the resistance genes can eventually reach humans through the food chain. The authors highlight the need for better strategies to reduce microplastic contamination in soil to help slow the growing crisis of antibiotic resistance.
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.
Distribution and major driving elements of antibiotic resistance genes in the soil-vegetable system under microplastic stress
Researchers investigated how microplastic contamination in agricultural soil affects the distribution and spread of antibiotic resistance genes through the soil-vegetable system. The study found that microplastic treatment promoted the enrichment of antibiotic resistance genes and mobile genetic elements in lettuce tissues, with higher polyethylene concentrations driving the spread of sulfonamide resistance genes from roots to leaves, suggesting microplastics may facilitate antibiotic resistance entering the food chain.
Fate and abundance of antibiotic resistance genes on microplastics in facility vegetable soil
This study found that microplastics in vegetable farm soils serve as hotspots for antibiotic resistance genes (ARGs), potentially amplifying the spread of antibiotic-resistant bacteria in agricultural environments. The co-presence of microplastics and ARGs in food-producing soils raises concerns about pathways for resistance genes to enter the food chain.
Interaction of Microbes with Microplastics and Nanoplastics in the Agroecosystems—Impact on Antimicrobial Resistance
This review examines how microplastics and nanoplastics in agricultural soil serve as hotspots for spreading antibiotic resistance genes between bacteria. The plastic particles provide surfaces where bacteria exchange genetic material, potentially accelerating the spread of drug-resistant microbes. This is a public health concern because resistant bacteria from farm soil can enter the food chain and make infections harder to treat.
Antibiotics and Antibiotic Resistance Genes in Animal Manure – Consequences of Its Application in Agriculture
This review examines how antibiotic resistance genes spread from animal manure used as fertilizer into agricultural soil and food crops. The widespread use of antibiotics in livestock creates resistant bacteria that survive in manure and can transfer their resistance to soil microbes and eventually to pathogens that affect humans. While focused on antibiotics rather than microplastics, this is relevant because microplastics in soil can also carry and spread antibiotic-resistant bacteria, compounding the risk to human health.
Food safety risks from soil-borne microplastics and antibiotic resistance across vegetable production and consumption pathways
This review examines how microplastics enter agricultural systems through plastic mulch degradation, wastewater irrigation, and organic amendments, and subsequently translocate into plant tissues. The study highlights that microplastics can also carry antibiotic resistance genes that persist through the food chain into human digestion, raising concerns about food safety from soil-borne microplastic contamination.
An Overview of Antibiotic Resistance and Abiotic Stresses Affecting Antimicrobial Resistance in Agricultural Soils
This systematic review found that soil contaminants from organic and chemical fertilizers, heavy metals, hydrocarbons, and untreated sewage sludge significantly promote antimicrobial resistance by increasing the abundance of antibiotic resistance genes in agricultural soils. Abiotic stresses like salinity and drought further amplify this effect. The findings connect to microplastic research because microplastics have been shown to serve as vectors for antibiotic-resistant bacteria and resistance genes in soil environments.
Antibiotic resistance in urban soils: Dynamics and mitigation strategies
This review examines how urban soils act as reservoirs for antibiotic-resistant bacteria, with microplastics identified as one of the sources spreading antibiotics and resistance genes through soil. The resistant bacteria can transfer to humans through direct contact, food, and water. The findings highlight an underappreciated way that microplastic pollution in cities could contribute to the growing antibiotic resistance crisis.
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.
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.
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.
Alteration of the migration trajectory of antibiotic resistance genes by microplastics in a leachate activated sludge system
This study found that microplastics in wastewater treatment systems actively promote the spread of antibiotic resistance genes (ARGs) by acting as a surface for resistant bacteria to colonise and as a vehicle that carries those genes from sludge into the liquid effluent. Adding microplastics to a leachate treatment system increased tetracycline resistance gene abundance and made them harder to eliminate. This matters because wastewater treatment plants are a critical barrier against antibiotic resistance spreading into the environment and ultimately into human communities.
Dynamic impact of polyethylene terephthalate nanoplastics on antibiotic resistance and microplastics degradation genes in the rhizosphere of Oryza sativa L.
This study found that PET nanoplastics in rice paddy soil boosted the spread of antibiotic resistance genes in soil bacteria by up to significant levels. The plastics provided surfaces for bacteria to grow on and produced toxic byproducts that sped up gene sharing between microbes. This means microplastic pollution in agricultural soil could make antibiotic-resistant infections harder to treat in people.
Effects and mechanisms of polystyrene micro- and nano-plastics on the spread of antibiotic resistance genes from soil to lettuce
Researchers investigated how polystyrene micro- and nanoplastics affect the spread of antibiotic resistance genes from soil into lettuce plants. They found that these plastic particles significantly increased the transfer of resistance genes by damaging root cell membranes and altering the microbial community in the soil around the roots. The study suggests that microplastic contamination in agricultural soils could make it easier for antibiotic-resistant bacteria to reach the food we eat.
Effects of coexistence of tetracycline, copper and microplastics on the fate of antibiotic resistance genes in manured soil
Researchers investigated how the co-presence of tetracycline, copper, and microplastics in manured agricultural soil affects antibiotic resistance gene (ARG) abundance, finding that microplastics amplified ARG spread when combined with the other stressors.
Microplastics as carriers of antibiotic resistance genes and pathogens in municipal solid waste (MSW) landfill leachate and soil: a review
This review examines how microplastics in landfill leachate and soil can serve as carriers for antibiotic resistance genes and disease-causing bacteria. Researchers describe how microplastic surfaces create favorable environments for bacterial colonization and gene transfer, potentially spreading antimicrobial resistance. The study highlights an underappreciated pathway through which plastic waste in landfills may contribute to the broader antibiotic resistance crisis.
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.
Effects of microplastics on dissipation of oxytetracycline and its relevant resistance genes in soil without and with Serratia marcescens: Comparison between biodegradable and conventional microplastics
This study found that biodegradable plastic (PBAT) microplastics actually slowed the breakdown of the antibiotic oxytetracycline in soil more than conventional polyethylene microplastics did, and both types promoted the spread of antibiotic resistance genes. This matters for human health because antibiotic-resistant bacteria from contaminated soils can eventually reach people through food or water.
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.
Nanoplastics promote the dissemination of antibiotic resistance genes and diversify their bacterial hosts in soil
Nanoplastics in soil were found to promote the spread of antibiotic resistance genes far more than larger microplastics, even at very low concentrations. The nanoplastics changed which bacteria carried resistance genes and enabled some bacteria to develop resistance to multiple antibiotics simultaneously. This is a significant concern for human health because nanoplastics in agricultural soil could accelerate the spread of drug-resistant bacteria that make infections harder to treat.
[Influencing Factors and Mechanisms of Antibiotic Resistance Gene Enrichment by Microplastics in the Environment].
This review examines how microplastics in the environment serve as carriers for antibiotic resistance genes, enriching and spreading resistant bacteria across air, soil, water, and sediments. Researchers found that the type, surface characteristics, and aging of microplastics all influence how effectively they accumulate resistance genes and facilitate horizontal gene transfer. The findings highlight the need to consider microplastics as an important vector in the environmental spread of antibiotic resistance.
Effects of microplastic degradability and concentrations on antibiotic resistance genes between soil and phyllosphere
Researchers investigated how biodegradable polyglycolic acid and non-degradable high-density polyethylene microplastics at varying concentrations affected antibiotic resistance gene distribution and transfer between soil and phyllosphere in a greenhouse germination experiment. They found that biodegradable microplastics had a more pronounced effect on antibiotic resistance gene abundance in the phyllosphere, while soil antibiotic resistance genes were jointly regulated by both microplastic type and concentration.
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.
