An attempt to reveal endocrine disruption in bluegill fish (Lepomis macrochirus) upon exposure to diazinon was made. Fish blood serum was collected and estradiol levels were measured following times of exposure to 60 μg / L of diazinon. Samples were

An effect of diazinon on brain acetylcholinesterase (AChE) activity of juvenile largemouth bass Micropterus salmoides was observed. The exposure concentration started from 1/10 of the 24-h LC50 value, 90 micrograms/liter. The exposure duration was 24
