Abstract EN
The effect of residual concentrations of organophosphate pesticide chlorpyrifos (Lorsban 4E) on the activity of the acetylcholinesterase enzyme and oxygen : nitrogen ratio in the mussel Aulacomya ater was analyzed.
Toxicity tests show a sensitivity to the pesticide in the bivalve estimated at 16 μg L-1 (LC50-96 hours).
Concentrations between 0.2 and 1.61 μg L-1 were able to inhibit significantly the AChE activity, and concentrations between 0.8 and 1.61 μg L-1 stimulate ammonia excretion and decrease oxygen : ammonia-N (O : N) ratio, with respect to the control group.
A.
ater proved to be a species sensitive to pesticide exposure and easy to handle in lab conditions.
Thus, it is recommended as a bioindicator for use in programs of environmental alertness in the Eastern South Pacific coastal zone.
