Lead nitrate toxicity on haematological changes in a live fish species Channa punctatus (Bloch)


Author(s): Beauty Dutta, Shikha Rani Sarma, Parag Deka

Abstract: The present investigation deals with the effect of lead nitrate on the haematological parameters on the model fish organism Channa punctatus. Most of the physicochemical parameters of experimental aquarium are maintained at optimal level. Although the concentration of FCO2 exceed beyond 15 mg.l-1 in certain time of experimental period, but is not act as a toxic substance under high concentration of DO (7.27±0.88 mg.l-1). Moreover, the effect of high concentration of FCO2 is minimal as the model organism is a live fish. The LC50 concentration where 50% death of the fishes occur is experimentally carried out which is found to be 600 mg.l-1. The fishes were treated at sub lethal concentration of LC50 (1/5th of LC50 concentration i.e. 120 mg.l-1) of lead nitrate for a period of 24hrs, 48hrs, 72hrs, and 96hrs to get haematological variations. The result shows that RBC and Hb% is decreased significantly following the exposure of lead nitrate in connection with time of exposure. Unlike RBC and Hb%, WBC is found to be increased with time. The examination of DLC shows that lymphocytes, basophil and eosinophil are increased as a function of time of exposure at sub lethal concentration; however, in neutrophil and monocytes the reversed phenomenon is discerned with significant variation.
