Sublethal concentration of bisphenol A induces hematological and biochemical responses in an Indian major carp Labeo rohita

This study aimed to determine the median lethal concentration (96-h LC50), acute and sublethal effects of malathion, an organophosphorus pesticide on hematological and biochemical responses in an Indian major carp, Labeo rohita. In this study, the LC50 value of malathion for 96 h was found to be 3.4 ppm. During acute (3.4 ppm) and sublethal [1/10th of 96 h LC50 value (0.34 ppm) studies, all the hematological parameters except WBC were significantly decreased (p<0.05). Besides, when compared with the control group, a significant (p<0.05) decrease in biochemical activity was also observed in malathion treated fish during acute and sublethal exposure periods. These results suggest that the tested concentrations of malathion could have significant adverse effects on the hematological and biochemical parameters of fish, Labeo rohita. The changes in the parameters can be effectively used to determine the impact of malathion in the aquatic ecosystem.

In the present study freshwater commercially cultivable Indian major carp Labeo rohita fingerlings was used to evaluate the synergistic effect of chlorpyrifos, an organophosphate insecticide and cypermethrin , a synthetic pyrethroid insecticide widely used in agricultural fields. The fishes were maintained at sublethal concentration for a period of 14 and 21 days. Histological examination was carried out in gills, liver and muscle at the end of exposure period to study the extent of damage at safe concentration.
