Abstract |
To determine if brain-acetylcholinesterase (AChE) inhibition in a marine teleost Lagodon rhomboides (pinfish) by an organophosphate pesticide (naled) is specific enough to diagnose anticholinesterase poisoning, brain-AChE inhibition by sublethal exposure in seawater was compared to brain-AChE inhigition caused by lethal exposure. A sublethal exposure did not inhibit brain-AChE as much as lethal exposure in periods of 24, 48, and 72 hr. Consistent levels of inhibition (84-89% inhibition) occurred when 40-60% of an exposed populaion of pinfish was killed. This correlation of brain-AChE inhibition with exposure and death in a fish population shows that brain-AChE measurements are of value in diagnosing anticholinesterase poisoning in a marine fish. |
