The current study has determined the toxicity effects of copper nanoparticles on the some vital organs such as gill, liver and kidney of Caspian Roach; Rutillus rutillus caspicus. For this purpose, 120 fishes were used as experimental samples and exposed to 0.1, 0.2 and 0.5 mg/L of Cu nanoparticles for 21 days, and 30 fishes assumed as the experiment control. The mean water temperature...

This study was conducted to evaluate the tissue of liver, gills and kidney Rutillus caspicus exposed to concentrations of 50, 100, 150 mg of Methyl tert-butyl ether, for 7, 14, 21 days. Average water temperature of 19±1 °C, water oxygen of 7.6 ± 0.2 mg/l and zero salinity were measured. A total of 156 fishes were studied in this experiment. In the first, second and third week of the test, three...
