Abstract

The current study examines the effects of vitamin C nanoparticles on fish health as well as the acute and long-term toxic effects of Fe2+ and Mn2+ combination on Nile tilapia, Oreochromis niloticus. The metal mixture under study has a detected 96-hour LC50 of 2.7% TU (Toxic unit). Fish were divided into four groups: Group 1, which served as the control group; Groups 2, 3, and 4 were exposed to 20% of the 96-hour LC50 for 30 days and fed on a conventional diet. Fish of Group 3 were supplemented with 20% vitamin C while fish of Group 4 were supplemented with 20% vitamin C as nanoparticles. The metals, levels in tissues of the liver and gills were examined, as well as the biochemical markers of metabolic processes in blood plasma. Fish from Group 2 displayed noticeable deteriorating conditions, followed by those from Group 3, whereas fish from Group 4 demonstrated noticeable good conditions across all examined criteria. Results showed that, while vitamin C nanoparticle proved to be more efficient, both vitamin C and its nanoparticles supplements had a positive impact on reducing the harmful effects of the studied metal mixture by chelating metal ions and scavenging free radicals. © (2024), (Japan Society on Water Environment).
