Relationship between toxicokinetics of carbaryl and effect on acetylcholinesterase activity in Pomacea patula snail.

The 96-h LC(50) value of carbaryl was 14.6 microg/mL for the snail Pomacea patula. Organisms were exposed for 72 h to a low sublethal concentration (0.1 of LC(50)) using a semistatic contamination system; bioconcentration and elimination experiments were performed evaluating simultaneously acetylcholinesterase (ACHase) activity. The inhibition of the… CONTINUE READING
