Summary

Researchers investigated the combined effects of amine-modified polystyrene nanoplastics and arsenic on a common freshwater cyanobacterium. They found that co-exposure intensified cellular stress, disrupted metabolic processes, and promoted the release of harmful toxins beyond what either pollutant caused individually. The findings reveal previously unrecognized risks to freshwater ecosystems when nanoplastics interact with heavy metal contaminants.

Polymers

This study uncovers how co-exposure to PSNPs-NH 2 and arsenic intensifies cyanobacterial stress, disrupts metabolism, and promotes toxin release, revealing new risks to aquatic stability and pollutant behavior.
