ClearAdsorption 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.
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 behaviors and mechanisms of antibiotic norfloxacin on degradable and nondegradable microplastics
Researchers investigated how degradable and nondegradable microplastics adsorb the antibiotic norfloxacin, comparing polybutylene succinate with conventional plastics to understand the environmental behavior and interaction mechanisms between these co-occurring pollutants.
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.
Adsorption of antibiotics on different microplastics (MPs): Behavior and mechanism
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.
Study of microplastics as sorbents for rapid detection of multiple antibiotics in water based on SERS technology
Researchers used polyethylene microplastics as sorbents combined with surface-enhanced Raman scattering (SERS) technology to rapidly detect multiple antibiotic residues in water, demonstrating that microplastics' tendency to adsorb contaminants can be repurposed as a tool for environmental monitoring.
The fate and risk of microplastic and antibiotic sulfamethoxazole coexisting in the environment
Researchers investigated sulfamethoxazole antibiotic adsorption onto polyamide microplastics and found that pH significantly influenced uptake, with adsorbed antibiotics more readily released in natural water than ultrapure water, posing environmental risks.
Sorption of selected pharmaceutical compounds on polyethylene microplastics: Roles of pH, aging, and competitive sorption
Researchers found that polyethylene microplastics adsorb pharmaceutical compounds including an antibiotic, a beta-blocker, and an antidepressant, with sorption capacity influenced by pH, aging of the plastic, and competition between compounds — raising concern about microplastics as carriers of pharmaceuticals in aquatic environments.

The occurrence of microplastic in specific organs in commercially caught fishes from coast and estuary area of east China
Researchers studied how polyethylene microplastics interact with the antibiotic ciprofloxacin in aquatic environments and found that the plastic particles can absorb and concentrate the drug on their surface. The adsorption capacity increased with weathering of the plastic, suggesting that aged microplastics in the environment are more effective carriers of pharmaceutical pollutants. The findings raise concerns that microplastics could transport antibiotics through water systems, potentially contributing to antimicrobial resistance.

Modeling of multicomponent adsorption equilibria of phenol and ciprofloxacin on pristine, acid-modified and thermo-oxidatively-aged polyethylene terephthalate microplastics
PET microplastics — both fresh and weathered — strongly adsorb the pharmaceutical antibiotic ciprofloxacin and the industrial chemical phenol from water, with adsorption in mixtures exceeding single-contaminant levels and a neural network model outperforming classical isotherms in predicting outcomes. This demonstrates that microplastics act as carriers concentrating multiple pollutants simultaneously, potentially delivering higher toxic doses to aquatic organisms than the individual chemicals would cause alone.
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.
