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.
pH-dependent effects of polystyrene microplastics on ciprofloxacin toxicity and uptake by ryegrass
This study found that the antibiotic ciprofloxacin accumulates more readily in plant shoots (leaves) under alkaline conditions, and that polystyrene microplastics at neutral and basic pH significantly worsen growth inhibition in ryegrass. The findings matter because much agricultural water and soil is neutral to slightly alkaline, meaning microplastic-antibiotic co-contamination may pose a greater risk to food crops than previously recognized.
Impact of polystyrene microplastics with combined contamination of norfloxacin and sulfadiazine on Chrysanthemum coronarium L.
Researchers examined the single and combined effects of polystyrene microplastics, norfloxacin, and sulfadiazine on the medicinal food crop Chrysanthemum coronarium. The study found that combined exposure altered nutrient element accumulation and caused ultrastructural damage to plant cells, suggesting that the co-occurrence of microplastics and antibiotics in soil may pose compounded threats to crop safety.
Combined toxic effects of enrofloxacin and microplastics on submerged plants and epiphytic biofilms in high nitrogen and phosphorus waters
Researchers studied the combined effects of the antibiotic enrofloxacin and microplastics on the submerged plant Myriophyllum verticillatum in nutrient-rich water.
