Haematotoxicity of integrated textile mill effluent to an air-breathing fish Heteropneustes fossilis (Bloch).

ABSTRACT

The effect of integrated textile mill effluent on the haematological characteristic of the fish Heteropneustes fossilis was studied. LC50 values were found to be 34%-38% on 96-24 h duration. Four sub-lethal concentrations were selected for this study. Exposure to effluent caused an increase in large lymphocytes, monocytes, neutrophils and basiphil granulocytes and decrease in small lymphocytes in H.fossilis.
