ClearAging-mediated selective adsorption of antibiotics by tire wear particles: Hydrophobic and electrostatic interactions effects
Tire wear particles (a major form of microplastic pollution on roads) become more porous and adsorptive after aging through freeze-thaw cycles or ozone exposure, increasing their capacity to carry certain antibiotics by up to 28-fold for fluoroquinolones. However, the same aging process reduces adsorption of sulfonamide and tetracycline antibiotics, reflecting how the chemistry of both the particle and the antibiotic interact. This shows that weathered tire particles on roadways and in waterways can act as vehicles for antibiotic transport, with implications for antibiotic resistance spread in the environment.
Adsorption and desorption behaviors of antibiotics by tire wear particles and polyethylene microplastics with or without aging processes
A comparison of antibiotic adsorption on tire wear particles (TWP) versus polyethylene microplastics found that UV-aged TWP had greater surface area increase and stronger adsorption of chlortetracycline and amoxicillin than aged PE, due to differences in surface chemistry and degradation susceptibility.
Adsorption of emerging micropollutants on tire wear particles
Researchers examined how tire wear particles (TWP) adsorb two common water pollutants—bisphenol A and 1H-benzotriazole—and how aging processes (photo, chemical, biological) affect that adsorption. TWP showed stronger adsorption of bisphenol A than benzotriazole, and aging altered sorption behavior, highlighting TWP as a significant carrier of micropollutants in aquatic environments.
Evolution of Microplastic Properties and Tetracycline Adsorption During Aging in Laboratory and Natural Environments
Researchers aged polyethylene, PET, and polystyrene microplastics under both laboratory UV and natural outdoor conditions and tracked how aging changed their physicochemical properties and tetracycline antibiotic adsorption capacity. Aging consistently increased surface oxidation and adsorption of tetracycline, with outdoor-aged particles showing different property profiles than lab-aged ones, highlighting the importance of using environmentally realistic aging conditions.
Desorption behavior of antibiotics by microplastics (tire wear particles) in simulated gastrointestinal fluids
Researchers investigated how antibiotics carried by tire wear particles are released in simulated human and fish digestive fluids. The study found that environmentally aged tire particles had more surface features that enhanced pollutant attachment, and that desorption rates were higher in human gastrointestinal fluid than in fish intestinal fluid, suggesting microplastic-carried antibiotics may pose a risk when ingested.
Biofilm-Colonized versus Virgin Black Microplastics to Accelerate the Photodegradation of Tetracycline in Aquatic Environments: Analysis of Underneath Mechanisms
Researchers found that biofilm-colonized tire wear particles accelerated the photodegradation of tetracycline in aquatic environments compared to virgin particles, revealing how microbial biofilms on microplastics can alter contaminant fate.
A study on the aquatic degradation of tire wear particles: Impact of environmental factors and material formulations
This study assessed how tire wear particles degrade in freshwater environments under varying environmental conditions including UV radiation and water chemistry. The degradation process alters particle properties in ways that may increase toxicity to aquatic organisms.
Impact of sequential UV-aging of microplastics on the fate of antibiotic (tetracycline) in riverine, estuarine, and marine systems
Researchers studied how sequential UV aging of polystyrene, polypropylene, and polyethylene microplastics, which mimics natural weathering, affects their ability to adsorb the antibiotic tetracycline under different water chemistry conditions. They found that aged microplastics adsorbed significantly more tetracycline than pristine particles, with the effect varying by water type and plastic polymer. The study suggests that as microplastics weather in the environment, they may become increasingly effective at carrying antibiotic contaminants.
A study on the aquatic degradation of tire wear particles: Impact of environmental factors and material formulations
This study investigated how tire wear particles degrade in aquatic environments, examining the effects of environmental factors such as UV exposure and water chemistry on particle breakdown. The results showed that aquatic degradation alters tire wear particles in ways that may increase their ecotoxicological risk.
Tetracycline adsorption trajectories on aged polystyrene in a simulated aquatic environment: A mechanistic investigation
Researchers found that aging of polystyrene microplastics in simulated aquatic environments progressively altered their surface properties and enhanced tetracycline antibiotic adsorption over time, with pseudo-second-order kinetics best describing the process, highlighting how weathered microplastics may increase antibiotic transport in aquatic systems.
When and how leachate toxicity of tire wear particles peaks: quantifying its dynamics using dose-response analysis
Researchers quantified how leachate toxicity from tire wear particles (TWP) changes with weathering over time, using aging experiments and toxicity bioassays to map the temporal dynamics of toxic compound release. Toxicity peaked during early weathering as soluble compounds leached rapidly, then declined, providing data relevant to risk assessment of TWP in stormwater runoff.

Researchers compared how different types of aged microplastics, including tire wear particles and biodegradable polylactic acid, adsorb the heavy metal lead from water.

Enhanced adsorption of oxytetracycline to weathered microplastic polystyrene: Kinetics, isotherms and influencing factors
Researchers compared how weathered and new polystyrene foam particles absorb the antibiotic oxytetracycline from water. They found that beached foam that had been exposed to environmental conditions absorbed roughly twice as much of the drug as virgin material, due to increased surface area and chemical changes from weathering. The study suggests that aged microplastics in the environment are more effective at picking up and transporting pharmaceutical contaminants.
A hidden route of exposure: adsorption of endocrine disrupting compounds and chemicals of emerging concern on tire rubber
Researchers investigated how tire wear particles, a major source of microplastics in the environment, adsorb endocrine-disrupting compounds and other emerging contaminants. Using batch experiments and LC-MS/MS analysis, they found that sorption was rapid and compound-specific, with tire rubber efficiently retaining antibiotics, hormonal compounds, and hydroxylated PAHs, indicating tire particles may serve as hidden transport vectors for these pollutants.

Researchers investigated how tire wear particles affect freshwater biofilms, which are communities of microorganisms that play important roles in aquatic ecosystems. They found that reactive chemical compounds on the surface of fresh tire particles caused significant toxicity, reducing photosynthesis and biological activity in the biofilms. The study suggests that aging in sewage environments reduces the toxicity of tire wear particles by breaking down these harmful surface chemicals.
