Polystyrene Microplastics as a Trojan Horse for Cadmium: Synergistic Apoptosis, Oxidative Stress, and Incomplete Recovery in Oreochromis niloticus

Summary

Scientists found that when tiny plastic particles (microplastics) and cadmium, a toxic heavy metal, team up, they cause more cell damage and stress in fish than either one does alone, acting like a "Trojan horse" that helps the metal get into the body. Even after exposure stopped, the fish didn't fully recover. This matters because it suggests microplastics in our environment could be secretly carrying and worsening the effects of other pollutants, raising questions about the combined risks we face from eating contaminated fish or being exposed to both pollutants together.
