Abstract

The aim of this study was to investigate the effects of chlorpyrifos (CPF), atrazine (ATR) and the mixture of them on acetylcholinesterase (AChE) and carboxylesterase (CbE) in brain and muscle of common carp, respectively. 220 carps were averagely divided into 11 groups according to the different treatments and concentration, including the exposure and recovery experiments. The activities of AChE and CbE of the brain and muscle were determined at the end of the exposure and the recovery. The results showed that in the control group, the specific enzymatic activities in the brain were higher than that in the muscle. The activities of AChE and CbE in the exposure groups were significantly lower than that in the control group except for the CbE activity in the ATR low-dose group. There was a negative dose-response relationship between the activities of AChE and CbE and the pesticides concentration. The activities of AChE and CbE in the recovery groups were significantly higher than that in the exposure group except for the CbE activity in the ATR low-dose group, AChE activity in the high-dose group of the mixture of ATR and CPF, and AChE activity of the brain in the CPF high-dose group. The results suggested that: (1) brain AChE may be considered as a very sensitive and early biomarker of exposure to CPF, ATR, or the mixture of ATR and CPF, (2) brain CbE may be used as a secondary biomarker for evaluating the exposure to CPF, ATR, or the mixture of ATR and CPF and (3) the change of the AChE and CbE activities caused by the mixture of ATR and CPF was more sensitive than that caused by the ATR or CPF alone.
