ClearInfluence of microplastics on the availability of antibiotics in soils
Researchers tested how three common types of microplastics affect the availability of antibiotics in different soil types. They found that microplastics significantly reduced the amount of antibiotics accessible in soil by providing extra binding sites and altering soil chemistry. The findings suggest that microplastic contamination in agricultural soils could change how antibiotics move through the environment.
Insights into behavior and mechanism of tetracycline adsorption on virgin and soil-exposed microplastics
Researchers studied how common microplastics absorb the antibiotic tetracycline, finding that soil-exposed plastics absorbed significantly more than fresh ones, with polylactic acid showing the greatest increase at 88%. The study revealed that environmental weathering changes how microplastics interact with antibiotics through different physical and chemical mechanisms. These findings are important for understanding how microplastics may carry and spread antibiotic contamination in soil environments.
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.

[Research Progress on Adsorption, Migration, and Compound Toxicity of Microplastics and Antibiotics in Soil].
This review examined how microplastics adsorb antibiotics in soil, drive their co-migration, and produce combined toxic effects on soil fauna, plants, and microorganisms. Hydrophobic partitioning, electrostatic interactions, and hydrogen bonding are the primary adsorption mechanisms, and co-exposure often amplifies toxicity to soil ecosystems.
Enhance in mobility of oxytetracycline in a sandy loamy soil caused by the presence of microplastics
Researchers used batch and column experiments to study how the presence of polyamide (PA) microplastics affects the sorption and transport of the antibiotic oxytetracycline (OTC) in sandy loamy soil. They found that PA microplastics increased soil pH and reduced overall OTC sorption, leading to enhanced mobility of the antibiotic through the soil column, raising concerns about accelerated antibiotic transport to groundwater in microplastic-contaminated agricultural soils.
Antibiotic 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.
Comparison of adsorption and desorption of triclosan between microplastics and soil particles
Researchers compared adsorption and desorption of triclosan on polyethylene and polystyrene microplastics versus soil particles, finding that PE had the highest adsorption rate and equilibrium capacity while PS and soil showed similar profiles. The results suggest that microplastics in soil environments can compete with soil particles for triclosan binding, potentially altering the contaminant's mobility and bioavailability.
Adsorption of antibiotics on microplastics
This study examined the adsorption of antibiotics onto different microplastic types, finding that sorption capacity depended on both the antibiotic's chemical properties and the plastic's surface characteristics, with implications for antibiotic transport in aquatic environments.
Adsorption interactions between typical microplastics and enrofloxacin: Relevant contributions to the mechanism
This study investigated how common microplastics (polyethylene, PVC, and polystyrene) absorb the antibiotic enrofloxacin from the environment. The researchers found that microplastics can effectively bind antibiotics through multiple chemical mechanisms, with the strength of binding depending on water conditions like acidity. This is concerning because microplastics carrying antibiotics could transport them into the food chain, potentially contributing to antibiotic resistance and affecting human health.
A contrasting alteration of sulfamethoxazole bioaccessibility in two different soils amended with polyethylene microplastic: In-situ measurement using diffusive gradients in thin films
Researchers found that polyethylene microplastics altered the bioaccessibility of the antibiotic sulfamethoxazole differently in two soil types, increasing it in sandy soil but decreasing it in clay soil, demonstrating that soil composition critically mediates microplastic-antibiotic interactions.
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.
Investigation of antibiotic clarithromycin adsorption potential on microplastics
Researchers investigated the adsorption potential of the antibiotic clarithromycin onto various microplastic types under controlled laboratory conditions, examining how surface properties and environmental factors influence pharmaceutical-microplastic interactions. The study found that microplastics can adsorb clarithromycin, raising concern about microplastics acting as vectors for antibiotic transport and spread in aquatic environments.

Researchers investigated how aging affects the adsorption of the antibiotic ciprofloxacin on polylactic acid and polyethylene microplastics, finding that aged plastics showed significantly enhanced adsorption capacity due to physicochemical surface changes.
Effects of heavy metals on the adsorption of ciprofloxacin on polyethylene microplastics: Mechanism and toxicity evaluation
Researchers studied how heavy metals in water affect the ability of polyethylene microplastics to absorb the antibiotic ciprofloxacin. They found that heavy metals competed with the antibiotic for binding sites on the microplastic surface, changing how much of each pollutant the plastic could carry. This is important because it shows microplastics in real-world environments may transport different combinations of pollutants, potentially delivering both antibiotics and heavy metals into the food chain.

The findings indicate microplastics can act as vectors transporting antibiotics through aquatic environments.
Aged polyamide microplastics enhance the adsorption of trimethoprim in soil environments
This study found that aged polyamide microplastics in soil significantly enhanced the adsorption of the antibiotic trimethoprim — more than 20 times greater than soil alone — through both surface sorption and pH alteration effects. This "enrichment effect" means that microplastics in agricultural soil can concentrate antibiotics, potentially increasing the risk of antibiotic resistance development and reducing the effectiveness of soil as a natural buffer against pharmaceutical contamination.
Microplastics play a minor role in tetracycline sorption in the presence of dissolved organic matter
Researchers studied the sorption of the antibiotic tetracycline onto microplastics in the presence of dissolved organic matter, finding that dissolved organics competed strongly for binding sites on microplastics, meaning real-world conditions substantially reduce microplastic uptake of tetracycline.
