STUDY OF EFFECTS OF SILVER NANOPARTICLES ON OXIDATIVE STRESS LEVEL AND ANTIOXIDANT IN CYPRINUS CARPIO FISH UNDER SOME ECOLOGICAL FACTORSIbraheem A. Shabeeb, Mohammed Q. al-Ani and Adel M. RabeeAbstract The present study was aimed to investigate the median lethal concentration of silver nanoparticles (AgNPs) toward common carp (Cyprinus carpio) prepared by chemical methods. Then, treating fish with silver nanoparticles under different environmental conditions (heat and ventilation). Then to study the functional, physiological changes after acute and chronic exposure to these concentrations. Where the lethal concentration was found for half of the experimental fish (1763 ppm) and that concentration was used to calculate safety concentrations. The presence of significant at P < 0.05 in each of the values in vitamins (A, E and C), and well in (GSH, SOD, CAT). Where there was a marked increase in the values of each of (A, E, SOD), and decrease in the values of each of (GSH, CAT and vit C). While there were no significant differences in (MDA) comparing with the control group. |
