ClearAdsorption 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 of Macrolide Antibiotics and a Metabolite onto Polyethylene Terephthalate and Polyethylene Microplastics in Aquatic Environments
Researchers studied how four macrolide antibiotics and a metabolite adsorb onto polyethylene terephthalate and polyethylene microplastics in water. They found that antibiotic adsorption followed a linear model, with PET showing higher adsorption capacity than polyethylene. The study suggests that microplastics in aquatic environments may serve as carriers for antibiotics, potentially affecting how these pharmaceutical pollutants are distributed in water systems.

Researchers investigated how four common microplastic types adsorb three antibiotics, finding that adsorption follows pseudo-second-order kinetics and Freundlich isotherms, with polymer type and antibiotic structure influencing sorption capacity and mechanism.
Adsorption characteristics of antibiotics on microplastics: The effect of surface contamination with an anionic surfactant
Researchers found that the common anionic surfactant SDBS coating polystyrene and polyethylene microplastics significantly altered their adsorption of the antibiotics oxytetracycline and norfloxacin. SDBS changed the surface charge and hydrophobicity of MPs in ways that increased antibiotic binding, suggesting surfactant-contaminated MPs pose a greater risk as antibiotic vectors 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.
Sorption of antibiotics onto aged microplastics in freshwater and seawater
Aged microplastics were found to sorb antibiotics from fresh and saltwater, with aging processes altering the surface properties of the plastic and increasing antibiotic binding capacity in some cases. The adsorption of antibiotics onto aged microplastics could facilitate their transport and delivery to aquatic organisms, potentially contributing to antibiotic resistance in environmental bacteria.
Sorption properties of tylosin on four different microplastics
This study tested the sorption of the antibiotic tylosin onto four types of microplastics, finding that sorption capacity varied significantly by plastic type, with implications for how microplastics may transport antibiotics through aquatic environments.
Sorption of pharmaceuticals on the surface of microplastics
Researchers tested the ability of four common microplastic types to adsorb nine pharmaceutical compounds frequently found as water pollutants. They found that sorption involved both hydrophobic and electrostatic interactions, but under natural environmental conditions the binding was relatively weak. The study suggests that while microplastics can interact with pharmaceutical residues, their role as carriers of these contaminants in real aquatic environments may be more limited than previously assumed.
Ecotoxicological effects of antibiotic adsorption behavior of microplastics and its management measures
This review summarizes research on how microplastics adsorb antibiotics from the environment, creating combined pollutant complexes with potentially greater ecological harm. Researchers found that factors like plastic type, aging, and environmental conditions strongly influence how much antibiotic a microplastic particle can carry. The study highlights that these microplastic-antibiotic combinations may contribute to the spread of antibiotic resistance in the environment.
Sorption of tetracycline antibiotics by microplastics, associated mechanisms, and risk assessments
Researchers systematically investigated how three common microplastic types adsorb tetracycline antibiotics. The study found that polystyrene had the highest adsorption capacity at 178.57 micrograms per gram, followed by PVC and polyethylene, and that PVC and polystyrene strongly retained the antibiotics with minimal desorption, raising concerns about compound pollution from microplastic-antibiotic combinations in the environment.
Microplastics as Potential Vector of Antibiotics in Aquatic Media: Environmental Implications
This review examined the role of microplastics as vectors for antibiotics in aquatic environments, highlighting how their small size, large surface area, and hydrophobicity enable them to concentrate organic pollutants. Co-exposure of microplastics and antibiotics can enhance bioaccumulation in organisms and amplify environmental risk.
Implications of polystyrene and polyamide microplastics in the adsorption of sulfonamide antibiotics and their metabolites in water matrices
Researchers found that polystyrene and polyamide microplastics can absorb sulfonamide antibiotics from water, with smaller particles and acidic conditions increasing absorption significantly. This means microplastics in the environment can act as carriers for antibiotics, potentially spreading antimicrobial resistance. The finding raises concerns because people may be exposed to both microplastics and the drugs they carry through contaminated water and food.

The impact of chlorination on the tetracycline sorption behavior of microplastics in aqueous solution
Researchers found that chlorination, a common disinfection step in wastewater treatment, alters the surface chemistry of microplastics and changes their capacity to adsorb tetracycline antibiotics, with chlorinated microplastics showing modified sorption behavior that affects their role as antibiotic carriers.
Interaction between antibiotics and microplastics: Recent advances and perspective
This review examines how microplastics in water can absorb antibiotic pollutants onto their surface, especially as the plastics age and develop bacterial biofilms. This interaction is concerning for human health because microplastics carrying antibiotics could promote antibiotic-resistant bacteria in waterways, making infections harder to treat.
