EFFECTS OF COPPER AND LEAD ON SOME HEMATOLOGICAL PARAMETERS OFn Oreochromis niloticus

摘要

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.n Micro-hematocrit methods were adopted in determining hematocrit levels and microscopic methods were used to determine MCV, erythrocyte numbers, erythrocyte and erythrocyte nucleus areas.n Hematocrit and MCV levels and
