Resumen:
No ecotoxicological information exists on phenanthrene (Phe) exposure in
cephalopods, animals of commercial and ecological importance. This study
investigated the effect of Phe on two B-esterases, Acetylcholinesterase
(AChE) and Carboxylesterases (CbE), in Octopus maya embryos. Octopus
embryos were exposed to different treatments: control (seawater),
solvent control (seawater and DMSO 0.01%), 10 and 100 mu g/L of Phe.
AChE and CbE activities were measured at different developmental stages
(blastula, organogenesis, and growth). B-esterase activities increased
in control and solvent control as the embryos developed, showing no
statistically significant differences between them. On the other hand,
the embryos exposed to Phe had significant differences from controls,
and between the high and low concentrations. Our results indicate that
B-esterases are sensitive biomarkers of exposure to Phe in O. maya.
Still, complementary studies are needed to unravel the toxicodynamics of
Phe and the implications of the found inhibitory effect in hatched
organisms.
