Abstract
The issue of water pollution by nanometals in aquatic bodies has become of increasing concern since the rapid development of metal nanoparticles (NPs). Despite the usage of these nanoparticles, they also have negative impacts on fish. This study sought to assess the acute combined effect of Aluminium and Zinc Oxide nanoparticles on Superoxide Dismutase and Malondialdehyde activities of x catfish (Clarias garienpinus) embryo/lavae The Organization for Economic Development (OECD) Fish Embryo Acute Toxicity Test (OECD 236) was employed. Superoxide Dismutase and Malondialdehyde activities were assessed using standard procedures. Fertilized embryos were exposed to different concentrations of Aluminium and Zinc Oxide nanoparticles (0, 0.5, 1, 10 μg/L) for 48 h. The results showed a significant (p < 0.05) dose-dependent decrease in MDA and SOD activities in fish embryo/larvae, indicating that nanoparticles-induced a significant reduction in MDA and SOD activities. The findings suggest that Aluminium Oxide and Zinc Oxide nanoparticles could potentially impact the MDA and SOD activities of fish which could invariably affect the survival of aquatic life, especially catfish'
