Sonochemically synthesized CuO-NPs: individual and synergistic toxicity assessment with sodium arsenite in adult zebrafish.

ABSTRACT: Sodium arsenite (NaAsO₂) and sonochemically synthesized copper oxide nanoparticles (CuO-NPs) pose escalating risks to aquatic animals due to their bio-accumulative potential, persistence, and interaction; when co-occurring, their combined effects represent a new class of emerging contaminants (ECs) with heightened ecological relevance. We synthesized CuO-NPs and characterized them using powder X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy and UV-visible spectroscopy. Zebrafish (Danio rerio) were exposed to NaAsO₂, CuO-NPs, and their combination for 28 days, and they were subjected to comprehensive histopathological analysis of muscle tissues and biochemical and genotoxic examinatio
