Bk. Das et Sc. Mukherjee, Chronic toxic effects of quinalphos on some biochemical parameters in Labeo rohita (Ham.), TOX LETT, 114(1-3), 2000, pp. 11-18
The effect of exposure to sublethal concentrations of the organophosphate p
esticide, quinalphos (1.12, 0.22 mg/l) on biochemical parameters of muscle
and enzyme activities in brain, liver and kidney of the Indian major carp,
Labeo rohita was studied after 15, 30 and 45 days. The muscle protein and R
NA levels decreased whereas DNA levels and acid phosphatase were elevated.
Similarly, alkaline phosphatase was depleted. The brain acetyl cholinestera
se activity was decreased most (- 75.43%) in 1.12 mg/l concentration over a
period of 45 days. Lactic dehydrogenase levels in brain and liver were ele
vated whereas in the kidney they were inhibited. Succinic dehydrogenase and
adenosine triphosphatase activities were depleted in brain, liver and kidn
ey. The effects have been discussed for different organ tissues in relation
to the pesticide. (C) 2000 Elsevier Science Ireland Ltd. All rights reserv
