Abstract:
This experiment was carried out to investigate whether there are any inhibitions of bovine liver catalase (CAT) activity by deltamethrin and alpha cypermethrin pesticides. CAT activity was inhibited by increasing deltamethrin and alpha cypermethrin pesticide concentrations from 0 to 500 ppm. Under the exposure of 25, 50, 100, 250 and 500 ppm deltamethrin concentrations, % CAT enzyme activity decreases were calculated as 7.3; 16.9; 25.5; 40.7 and 62.7%, respectively. Under the exposure of 25, 50, 100, 250 and 500 ppm alpha cypermethrin concentrations, % CAT enzyme activity decreases were calculated as 2.3, 3.0, 10.2, 13.8 and 16.3%, respectively. Deltamethrin and alpha cypermethrin inhibited CAT non-competitively.
