Abstract

The widespread use of zinc oxide nanoparticles (ZnO NPs) in various products raises significant ecological concerns due to their potential toxic effects in aquatic environments. This study employed the Asian green mussel (Perna viridis) as a model to explore the molecular and ecological risks of ZnO NP exposure using transcriptomics. Mussels exposed to ZnO NPs (5, 10, and 15 mg/L) for 28 days showed significant gene expression changes in gill tissues, affecting immune response, calcium homeostasis, and cellular stress. Disrupted pathways such as FOXO, Wnt, and TGFβ reveal complex toxicity mechanisms. These findings provide crucial insights into the environmental impact of nanoparticle pollution, emphasizing the need for stringent regulations. Furthermore, the shared molecular pathways suggest that similar mechanisms may occur in humans, highlighting potential health risks associated with nanoparticle exposure.
