Description
Summary:The purpose of the investigation was to study the effect of inorganic mercury on the morphology of erythrocytes in a freshwater fish Anabas scandens. An enlargement of red blood cells and striking differences in morphology were seen in exposed fish within 7 days when compared to control fishes. After 28 days the red cell membrane was ruptured with disintegration of nucleus and cell membrane in some cells . Complete haemolysis and disappearance of cell membrane was marked after 35 days exposure. The drastic depletion in haematocrit values and depletion in red cell count and haemoglobin percentage confirms the view that mercury is the cause of haemolysis.
