Acetylcholinesterase activity, antioxidant defenses, and lipid peroxidation in the clam Semele solida: Can this species be used as a bioindicator?

We analyzed the relationships between biochemical parameters: acetylcholinesterase activity (AChE); glutathione S-transferase activity (GST); glutathione concentration (GSH) and lipid peroxidation; in the bivalve mollusc Semele solida, with the effects of environmental stress (anthropogenic activity...

The biochemical parameters analyzed in specimens from Coliumo estuary, differed significantly from that in Andalién estuary, with lower AChE activity in gill tissue (2189.9 ± 189.6 µmol min¹mg protein¹) and intracellular GSH levels (59.8 ± 13.3 µM), and the highest lipid peroxidation (31.9 ± 7.4 nmol MDA mL¹) and GST activity (614.9 ± 92.3 µmol min¹mg protein¹).
