Abstract
An effect of diazinon on brain acetylcholinesterase (AChE) activity of juvenile largemouth bass Micropterus salmoides was observed. The expo sure concentration started from 1/10 of the 24-h LC50 value, 90 mu g/l iter. The exposure duration was 24 h. Statistically significant and do se-dependent reductions in the mean AChE activities we seen at 90, 180 , 270, 360, and 450 mu g/liter. The results show that juvenile brain a cetylcholinesterase activities were significantly inhibited by subleth al doses of diazinon. Inhibition of brain AChE will definitely cause p hysiological and behavioral modifications that reduce survival ability of the animals at an early stage Of growth. (C) 1998 Academic Press.
