Toxicological effect of Al 2 O 3 nanoparticles on histoarchitecture of the freshwater fish Oreochromis mossambicus

In the present study, freshwater fish Oreochromis mossambicus were exposed to sub lethal concentrations (120, 150 and 180 ppm) of Aluminium oxide nanoparticles (Al O NPs) for 96 h. Histological abnormalities were not observed in the organs of control fishes whereas severe damages and extensive archi...

Description
Summary:In the present study, freshwater fish Oreochromis mossambicus were exposed to sub lethal concentrations (120, 150 and 180 ppm) of Aluminium oxide nanoparticles (Al O NPs) for 96 h. Histological abnormalities were not observed in the organs of control fishes whereas severe damages and extensive architectural loss was found in the brain, gill, intestine, kidney and muscle tissues of treated fishes with more pronounced effects in 180 ppm. The results showed that the acute exposure to Al O NPs altered the histoarchitecture in various fish tissues.
