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.
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.

The findings highlight an underappreciated way that microplastic pollution in cities could contribute to the growing antibiotic resistance crisis.
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.
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.
Long-term application of organic fertilizer prompting the dispersal of antibiotic resistance genes and their health risks in the soil plastisphere
Scientists found that microplastics in farmland soil treated with organic fertilizer for over 30 years created a "plastisphere" that amplified the spread of antibiotic resistance genes by 1.5 times and increased the risk of these genes jumping between bacteria by 2.7 times. This is concerning for human health because antibiotic-resistant bacteria from agricultural soils can eventually reach people through food and water.
How micro-/nano-plastics influence the horizontal transfer of antibiotic resistance genes - A review
This review examines how micro- and nanoplastics help spread antibiotic resistance genes between bacteria -- a major global health threat. The tiny plastic particles can act as platforms where bacteria exchange DNA carrying drug-resistance instructions, potentially making infections harder to treat. The effect depends on the type, size, and concentration of plastics, and has been documented in sewage, livestock farms, and landfills.
Is the application of organic fertilizers becoming an undeniable source of microplastics and resistance genes in agricultural systems?
Organic fertilizers such as compost, manure, and biosolids are increasingly recognized as significant pathways for both microplastics and antibiotic resistance genes (ARGs) to enter agricultural soils. Microplastics in these fertilizers can carry and protect antibiotic-resistant bacteria, potentially spreading resistance through the food chain. The review identifies high-temperature composting as a partial solution for reducing ARGs but notes that effective methods for removing microplastics from organic fertilizers remain limited.
Source, occurrence, migration and potential environmental risk of microplastics in sewage sludge and during sludge amendment to soil
This review examines microplastics in sewage sludge and the risks of applying sludge as agricultural fertilizer, finding that sludge acts as both a sink for sewage microplastics and a source when spread on fields. Co-accumulated heavy metals, antibiotics, and antibiotic resistance genes on microplastics further complicate the environmental risks of sludge amendment to soils.

This review examines how water, soil, and air act as reservoirs for antibiotic-resistant bacteria, with microplastics highlighted as one of several agents that help spread drug-resistant genes across environments. The findings matter for human health because microplastics can carry antibiotic-resistant bacteria from wastewater and agricultural runoff into water supplies and food systems.
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.
A Review of Antibiotics, Antibiotic Resistant Bacteria, and Resistance Genes in Aquaculture: Occurrence, Contamination, and Transmission
This review examines how overuse of antibiotics in fish farming leads to antibiotic-resistant bacteria and resistance genes that spread through water, sediment, and the organisms themselves. This is relevant to microplastic pollution because microplastics in aquaculture environments can carry antibiotic-resistant bacteria, potentially transferring these dangerous genes to humans through the food chain.
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.

This chapter reviews how microplastics accumulate in agricultural soils via sewage sludge and compost applications, adsorb heavy metals, organic pollutants, and antibiotics, and transport these contaminants into farmland, posing risks to the food chain and human health.
Antibiotic Resistance Genes in Food Animal Production: Environmental Implications and One Health Challenges
This review examines how antibiotic use in livestock and aquaculture contributes to the spread of antimicrobial resistance genes across the human-animal-environment interface. Researchers found that a substantial proportion of resistance genes detected in farm environments are shared with those found in human clinical settings. The study emphasizes the need for a One Health approach to surveillance and highlights the role of environmental reservoirs, including those contaminated with microplastics, in disseminating resistance.
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.
Are microplastics in livestock and poultry manure an emerging threat to agricultural soil safety?
This review examines the overlooked problem of microplastics in livestock and poultry manure, which enters agricultural soil when manure is used as fertilizer. Manure processing can actually make microplastics smaller, rougher, and more numerous, and the particles often carry additional pollutants like heavy metals, antibiotics, and pathogens. This creates a concerning cycle where microplastics from animal feed and farm equipment contaminate manure, which then introduces these particles directly into cropland and the food supply.
