Abstract:

Titanium dioxide nanoparticles (TiO2 NPs) are widely used nanomaterials because of their photocatalytic characteristics and capacity to absorb ultraviolet light at specific wavelengths. This study investigated the toxicological effects of rutile TiO2 nanoparticles on Channa punctatus by assessing their influence on adult individuals. The adult toxicity test examined the effects of TiO2 NPs on oxidative damage in the gill tissue. The presence of antioxidant enzymes, namely superoxide dismutase (SOD), catalase (CAT), and glutathione S transferase (GSTs), was identified in gills of channa punctatus. The results suggested that extended exposure to TiO2 nanoparticles can cause oxidative damage to gills. Moreover, extended exposure to TiO2 nanoparticles can result in increased levels of catalase (CAT), superoxide dismutase (SOD), and glutathione S-transferases (GSTs) in gills of mature channa punctatus as a defensive reaction against adverse effects. The gill of mature channa punctatus displayed more prominent effects after prolonged exposure to TiO2 nanoparticles
