Abstract
This study was conducted to investigate the effect of exposure to fenitrothion thermal fogging on some biological and biochemical parameters in New Zealand white rabbits as a non-target organism. Fenitrothion 50EC, diluted with diesel (1: 39), was applied by thermal fogging at the recommended rate 10 L ha(-1). Rabbits, individually caged, were exposed to the pesticide for 30 days, day after day. The results showed a significant reduction in the body weight (13.34%) compared with the control; on the contrary, weights of liver, heart and lungs increased by 23.37, 20.23 and 14.76%, respectively. A reduction in brain, blood, plasma, and erythrocytes cholinesterase (ChE) activity was observed after 15 and 30 days of exposure. The blood, plasma and RBCs' ChE was more sensitive than the brain enzyme. After 30 days of recovery, all tested biological parameters returned to their normal values.
