Impact of organophosphates on blood serum enzymes of Indian major carps

Abstract

The present study was carried out to envisage the impact of malathion, chlorpyrifos and dimethoate on the levels of blood serum enzymes of Labeo rohita and Cirrhinus mrigala. Increase upto 22.17%, 23.92%, 26.6% and 50.3% have been observed in the levels of LDH of C. mrigala exposed to D (0.001 ppm), C (0.001 ppm), M (0.001 ppm) and OPs in combination respectively. L. rohita fishes were exposed to D, C, M (0.001 ppm) and D+C+M exhibit increase in LDH level upto 18.95%, 20.6%, 25.6% and 44.8% has been observed respectively. Maximum increase i.e. 44.2% and 45% in levels of ALP was recorded in fishes exposed to D+C+M (0.001 + 0.001 + 0.001 ppm) in L. rohita and C. mrigala respectively. Decrease in ALP upto 23% and 33.1% have been observed in fishes exposed to D+C+M (0.001 + 0.001 + 0.001 ppm) in L. rohita and C. mrigala respectively.
