After estimating the LC50 of fly ash, fishes were exposed to different concentration of fly ash (200g/l, 400g/land 600 g/l) for a period of one week. The haematological parameters like haemoglobin (Hb), total erythrocyte count (TEC), packed cell volume (PCV) and total leucocyte count (TLC) were estimated. The absolute values like mean cell haemoglobin (MCH), mean cell haemoglobin concentration (MCHC) and mean cell volume (MCV) were calculated from the above parameters. There was significant alteration in all the haematological parameters on exposure to fly ash. Erythrocyte indices showed decrease from the control value whereas there was significant increase in total leucocyte count indicating stressful condition.
