Combined toxic effects of nanoplastics and norfloxacin on mussel: Leveraging biochemical parameters and gut microbiota
Researchers exposed mussels to nanoplastics and the antibiotic norfloxacin, both alone and together, and found that the combination caused greater biochemical stress than either pollutant alone. Nanoplastics appeared to carry the antibiotic into mussel tissues, increasing its bioavailability and impact on gut microbiota. The findings suggest that nanoplastics can amplify the toxicity of other contaminants in marine organisms.
Microplastics and co-pollutant with ciprofloxacin affect interactions between free-floating macrophytes
Researchers found that polyethylene microplastics and ciprofloxacin co-pollutants altered competitive interactions between free-floating macrophytes, with combined exposure affecting plant growth and physiological responses differently than individual pollutant exposure.
Single and combined effects of polystyrene nanoplastics and Cd on submerged plants Ceratophyllum demersum L.
Researchers studied the combined effects of nanoplastics and cadmium, a toxic heavy metal, on the aquatic plant Ceratophyllum demersum. They found that nanoplastics worsened cadmium's harmful effects on plant growth, photosynthesis, and cellular health, reducing growth rates by over 35%. The study suggests that when nanoplastics and heavy metals co-occur in water, their combined impact on aquatic plants may be more severe than either pollutant alone.
Interactive effects of selected pharmaceutical products (metronidazole, diclofenac, ibuprofen) and differently functionalized nanoplastics on marine algae Chlorella sp.
The combined toxicity of three pharmaceutical products (metronidazole, diclofenac, ibuprofen) and polystyrene nanoplastics with different surface functionalization (NH2 and COOH) was tested on marine algae Chlorella sp. Polystyrene nanoplastics at 1 mg/L caused substantial growth inhibition, while combining pharmaceuticals with nanoplastics reduced rather than amplified toxicity.
