Cover Story: Engineered ZnO nanoparticles are increasingly entering aquatic systems, yet their ecological impact remains poorly defined. Here, we show that silver doping, despite causing only minor structural shifts, dramatically alters toxicity dynamics in Artemia salina. Pure ZnO exhibited LC50 values of 358 ppm (24 h) and 64 ppm (48 h), whereas Ag-ZnO shifted to 607 ppm and a striking 28 ppm, respectively. This pronounced increase in 48 h lethality reveals how small compositional changes can amplify long-term biological effects, emphasizing the critical need for dopant-specific and time-resolved nanotoxicological evaluations.
