Histopathological and Ultrastructure Alteration Of Gills in Common Carp (Cyprinuscarpio L.) After Long Time Exposure to Zinc Oxide Nano particles .
This study aimed to assess the toxicity and severity of zinc oxide nanoparticle (ZnO-NPs) in the tissues of gills. Therefore, carp fish (Cyprinus carpio) were subjected to sub-lethal concentration of (ZnO-NPs) 9mg/l for periods of (7, 14, 21, 28, 35, 42) days that led to a histopathological and ultr...
