| Abstract: | The LC50-value of diazinon for Brachydanio rerio decreases from 2.3 to 2.12 mg/1 during the time from 24 to 96 h. In the course of exposure for 24 to 288 h against 0.26 to 2.08 mg/1 diazinon the activity of acetylcholinesterase as well as acid and alkaline phosphatases decreases to 20.… 30% as a minimum. The decrease of the enzymatic activities in the brain tissue is more time-dependent than concentration-dependent, which may de due to the respective metabolites of diazinon. |
