Abstract - Issue Jul 2010, 31 (4) BackAnalysis of AchE and LDH
in mollusc, Lamellidens
marginalis after exposure to chlorpyrifos P.G.
Department of Zoology, Jamal (Received: Abstract: The enzymes Acetylcholinesterase
(AchE) and Lactatedehydrogenase
(LDH) are used as biological markers in the present study.? Enzymes are highly sensitive and used to
evaluate the biological effects of organophosphate pesticide chlorpyrifos in freshwater mussel Lamellidens
marginalis. The test organisms were exposed to
sub-lethal concentration (5 ppm) of chlorpyrifos? for 30 days and allowed to recover for
seven days.? A distinct reduction of the
enzyme AchE (34 + 3.3 U l-1) was
found in the treated hepatopancreas. A significant
increase in LDH activity in gill, hepatopancreas and
muscle was observed.? There was a
significant recovery in AchE and LDH? in the different tissues, after seven
days recovery period..? Hence, the
changes in the enzymes are found as the best biomarkering
tool to evaluate the effect of organophosphate pesticide chlorpyrifos
on the aquatic biota. Key words: Biomarker, LDH, Acetylcholinesterase,
