Summary

Researchers exposed zebrafish (Danio rerio) to microplastics (10 µg/L) and copper (45 µg/L) individually and in combination, finding that fish exposed to both stressors simultaneously exhibited higher oxidative stress across multiple body organs than those exposed to either contaminant alone.

This study investigates the combined effects of microplastics and copper on oxidative responses in zebrafish. Fish were exposed to 10 µg/L microplastics and 45 µg/L copper, both individually and in combination. Oxidative responses were measured in various body organs, revealing that fish exposed to both stressors simultaneously exhibited higher oxidative stress compared to those exposed to either microplastics or copper alone.
