Phenolic industrial wastes of the Bhilai Steel plant (Chhattisgarh,India)

Haematological indices are important parameters to evaluate the general physiological status of fishes and may be considered as stress indicators for estimation of the response reactions of the fish to various environmental conditions (Docan et al., 2010). It may be considered useful in assessing the health of fish subjected to changing environmental conditions (Blaxhall, 1972 and Nair et al, 1984) and have proven useful in monitoring stress responses as bio-indicators (Bridges et al, 1976; Soivio & Oikari, 1976) The phenolic industrial wastes generated from the cock oven of steel plants and dumped in river are changed the nature of aquatic environment and pose serious threats to aquatic life. The present study describes the daily changes in the haematological parameters (TEC, TLC and % of Hb) of the Indian Murrell Channa punctatus (Bloch) upon long term exposure to high concentration of phenolic effluents of Bhilai steel plant. Commercial available phenol was also taken in Same concentration for comparison. During experiment over all % increase in TEC was found, highest augmentation in TLC and % changes in Hb was occurred.
