ClearThe co-presence of polystyrene nanoplastics and ofloxacin demonstrates combined effects on the structure, assembly, and metabolic activities of marine microbial community
Researchers examined the combined effects of polystyrene nanoplastics and the antibiotic ofloxacin on marine microbial communities. They found that the two pollutants together had a greater impact on bacterial community structure and metabolic activity than either one alone. The study suggests that nanoplastics and antibiotics co-occurring in the ocean may work together to disrupt the microorganisms that support marine ecosystem health.

Unraveling the combined impacts of pristine and aged polyethylene microplastics and the ciprofloxacin antibiotic on sediment microbial communities and ecological functions
Researchers examined how polyethylene microplastics — both fresh and environmentally weathered — interact with the antibiotic ciprofloxacin to affect the microbial communities living in aquatic sediments. They found that microplastics, especially in combination with the antibiotic, disrupted microbial community structure and simplified the ecological networks that microbes rely on for stable functioning. This is concerning because healthy sediment microbe communities underpin nutrient cycling and ecosystem health, and their disruption by combined plastic-antibiotic pollution could have cascading effects.

Impacts of nano- and micro-plastics exposure on zooplankton grazing, bacterial communities, and dimethylated sulfur compounds production in the microcosms
Researchers investigated how nano- and microplastics affect zooplankton grazing, bacterial communities, and the production of climate-relevant dimethyl sulfide compounds. The study found that plastic particle exposure reduced zooplankton feeding rates and disrupted dimethyl sulfide production in a dose- and size-dependent manner, with nanoplastics showing greater toxicity than larger microplastics.
Effects of micro- and nano-plastics on community assemblages and dimethylated sulfur compounds production
Researchers conducted a field microcosm experiment to study how micro- and nanoplastics affect marine plankton communities and the production of climate-relevant sulfur compounds. They found that medium and high concentrations of polystyrene, polyethylene, and polyamide particles disrupted zooplankton grazing and altered the production of dimethyl sulfide. The study suggests that plastic pollution could interfere with marine biogeochemical cycles that play a role in climate regulation.
