The copper accumulation in liver and gill tissues of Oreochromis niloticus, exposed to 2 ppm Cu and 1g/L clinoptilolite singly and to the same concentrations of their mixture over 24, 48, 72 and 96 hours was studied. ICP-AES spectrophotometer techniques were applied in determining tissue copper levels. Statistical evaluation of the experimental data was carried out by Student Newman Keul’s procedure. No mortality was observed during the experiments. Copper accumulation was lower in metal-clinoptilolite mixture group than metal singly group in gill tissue while no accumulation in both experimental groups in liver tissue (P

Effects of sub-lethal concentrations of copper and lead on hematocrit and mean cell volume (MCV) levels and on erythrocyte numbers, erythrocyte and erythrocyte nucleus areas were determined after exposing Oreochromis niloticus to 4 ppm Cu and 0.2 ppm Pb over 7, 15 and 30 days. Micro-hematocrit methods were adopted in determining hematocrit levels and microscopic methods were used to determine MCV, erythrocyte numbers, erythrocyte and erythrocyte nucleus areas. Hematocrit and MCV levels and erythrocyte and nucleus areas increased significantly (P
